Description
Overview
Opto 22 offers a complete line of SSRs, from the rugged 120/
240/380-volt AC Series to the small footprint MP Series,
designed for mounting on printed circuit boards. All Opto 22
SSRs feature 4,000 volts of optical isolation, and most are UL
and CSA recognized. The innovative use of room-temperature
liquid epoxy encapsulation, coupled with Opto 22’s unique
heat-spreader technology, are key to mass producing the
world’s most reliable solid state relays.
In 1974, Opto 22 introduced the first liquid epoxy-filled line of
power solid-state relays (SSR). This innovation in SSR design
greatly improved the reliability and reduced the cost of
manufacturing. At that time, we also incorporated into our
manufacturing process 100% testing under full load
conditions of every relay we produced.
By 1978, Opto 22 had gained such a reputation for reliability
that we were recognized as the world’s leading manufacturer
of solid-state relays. Through continuous manufacturing
Every Opto 22 solid state relay is subjected to full load test and
six times the rated current surge both before and after

encapsulation. This double testing of every part before it
leaves the factory means you can rely on Opto 22 solid state
relays. All Opto 22 SSRs are guaranteed for life.
MP Series
The MP Series packaging is designed with a minimum
footprint to allow maximum relay density on the printed
circuit board.
Accessories for the Power-Series SSRs include a safety cover,
heatsink, and a matching thermal conductive pad. See page 3.
P Series
The P Series power relays provide low-profile [0.5 in.
(12.7 mm)] center mounting on printed circuit boards.
Power Series SSRs
Opto 22 provides a full range of
Power Series relays with a wide
variety of voltage (120–575 volts)
and current options (3–45 amps).
All Power Series relays feature 4,000
volts of optical isolation and have a
high PRV rating. Some Power Series
relays include built-in LEDs to
indicate operation.
HS Series SSRs
The HS Series features an integrated
heatsink, which makes them so cool.
These relays have less thermal
resistance inside, so heat dissipates
more easily than in a standard SSR
mounted to the same heatsink. With
the heatsink built-in, you don't have
to select one from a catalog, and
installation is much easier. See
page 13.
See page 4.
DC Series
The DC Series delivers isolated DC control to large OEM
customers worldwide. All DC control SSRs are LS TTL
compatible.

HS Series Specifications
The HS Series features an integrated heatsink, which makes them so cool. Because there is less thermal resistance internal to the
unit than in a standard SSR mounted to the same heat sink, heat dissipates more easily. The built-in heatsink means you don't
have to select a heatsink, and installation is much easier. Each HS-series SSR has built-in hardware for screw mounting and a built-
in DIN-rail adapter clip for mounting to a 35mm DIN rail.

Solid-State Relays
Applications: Tips
Heat Sink Calculation
Like all semiconductor devices, SSR current ratings must be based on maximum internal junction temperature. All Opto 22 SSRs
operate conservatively at maximum internal junction temperatures of 110 °C. Use the equation below to calculate the maximum
allowable heat sink thermal resistance for your application. It is good engineering practice to provide a margin for error instead of
running the application right at the limits. If your application is near the thermal limit, it can be helpful to add a fan to move air
across the heat sink.
IMPORTANT: Thermally conductive grease must be used between the relay base and the heat sink.
Sample Calculation 1
120-volt, 20-amp load; 50 °C ambient air temperature
Model: 120D25 SSR.
See the last two columns of the table on page 4 for thermal resistance and dissipation values for the 120D25. Also, see the note at
the bottom of the table.
Dissipation: 1.3 watts/amp
Thermal resistance: 1.2 °C/watt
Maximum junction temperature: 110 °C
The calculation would be as follows:
This calculation indicates that you
should select a heat sink with a thermal
resistance of less than 1.1 °C/watt.

See the last two columns of the table on page 4 for thermal resistance and dissipation values for the 240D45. Also, see the note at
the bottom of the table.
Dissipation: 0.9 watts/amp
Thermal resistance: 0.67 °C/watt
Maximum junction temperature: 110 °C
The calculation would be as follows:
This calculation indicates that you should
select a heat sink with a thermal resistance
of less than 4.6 °C/watt.
Duty Cycle Calculation
When solid-state relays are operated in an on/off mode, it may be advantageous to calculate the RMS value of the current through
the SSR for heat sinking or determining the proper current rating of the SSR for the given application.
IRMS = RMS value of load or SSR
T1 = Time current is on
I RMS
=
(ION)2 x T1
T1 + T2
T2 = Time current is off
ON = RMS value of load current during on period

Solid-State Relays
Transformer Loads
Control Current Calculation
Careful consideration should be given to the selection of the
proper SSR for driving a given transformer. Transformers are
driven from positive saturation of the iron core to negative
saturation of the core each half cycle of the alternating
voltage. Large inrush currents can occur during the first half
cycle of line voltage if a zero-voltage SSR happens to turn on
during the positive half cycle of voltage when the core is
already in positive saturation. Inrush currents greater than 10
times rated transformer current can easily occur. The following
table provides a guide for selecting the proper SSR for a given
transformer rating.
All Opto 22 DC-controlled SSRs have a control circuit
consisting of 1000 ohms in series with an Optocoupler LED.
The LED will drop 1 volt, so the voltage across the internal
resistor will be 1 volt less than the control voltage.
The control current (IC ) can be calculated from the control
voltage (VC ) as follows:
IC = (VC - 1)/1000
Examples:
3 VDC control voltage:
IC = (3 - 1)/1000 = 0.002 A (2 mA)
32 VDC control voltage:
IC = (32 - 1)/1000 = 0.031 A (31 mA)
For control voltages above 32 VDC, an external resistor can be
added in series with the SSR to limit the control current. Also, if
the device driving the control current to the SSR is limited, you
can limit the control current by using an external resistor (R ).
e
I = (V - 1)/ (R + 1000)
e
C
C
R = [(V - 1)/(I )] -1000

To limit the control current to 2 mA, this simplifies to:
R = 500 (V - 3)

Solenoid Valve and Contactor Loads

In applications requiring higher voltage, two Opto 22 SSRs
may be operated in series for double the voltage rating. The
built-in snubber in each SSR assures proper voltage sharing of
the two SSRs in series. In the following diagram, two 240-volt,
45-amp SSRs are connected in series for operation on a 480-

Heater Loads
Single-Phase Reversing Motor Control (cont.)
Care should be taken in selecting a SSR for driving a heater
load if the load is cycled on and off in a continuous manner as
might occur in a temperature control application. Constant
cycling can cause thermal fatigue in the thyristor chip at the
point where the chip bonds to the lead frame. Opto 22
employs a thick copper lead frame for mounting the SCR chips
in the power series SSRs to eliminate thermal fatigue failures.
In addition, Opto 22 recommends operating any SSR at 75%
rated current for cycling heater loads to ensure complete
reliability.
The following table is a guide to selecting the proper SSR for a
given heater load.
The resistors are unnecessary if the control circuit is designed
to ensure that one SSR is off before the other SSR is on.

The circuit diagram below illustrates a typical 1 Ø motor
winding inductance and the phase shift capacitor can cause
twice-line voltage to appear across the open SSR. A 240-volt
SSR should be used for a 120-volt line. During the transition
period when one SSR is turned on and the other SSR is going
off, both SSRs may be on. In this case, the capacitor may
discharge through the two SSRs, causing large currents to
flow, which may destroy the SSRs. The addition of RL as shown
will protect the SSRs from the short circuit capacitor discharge
current.
Three-phase motors may be controlled by solid-state relays as
shown. A third SSR as shown is optional, but not necessary.
The control windings may be connected in series or parallel.
Care should be taken to ensure that the surge current drawn
by the motor does not exceed the surge current rating of the
SSR.

Q : What is a solid-state relay?
A: A solid-state relay (SSR) is a semiconductor device that can
be used in place of a mechanical relay to switch electricity to a
load in many applications. Solid-state relays are purely
electronic, normally composed of a low current “control” side
(equivalent to the coil on an electromechanical relay) and a
high-current load side (equivalent to the contact on a
conventional relay). SSRs typically also feature electrical
isolation to several thousand volts between the control and
load sides. Because of this isolation, the load side of the relay is
actually powered by the switched line; both line voltage and a
load (not to mention a control signal) must be present for the
relay to operate.
Three-Phase Reversing Motor Control
Three-phase reversing motor control can be implemented
with four SSRs as shown in the connection diagram. The SSRs
work in pairs with SSR1 and SSR3 operated for rotation in one
direction and SSR2 and SSR4 operated for rotation in the
reverse direction. The resistor R1 as shown in the connection
diagram protects against line-to-line shorts if SSR1 and SSR4
or SSR3 and SSR2 are on at the same time during the reversing
transition period. Use the following table as a guide to the
proper selection of an SSR for this application.
Q : What are the advantages of using an SSR over a
mechanical relay?
A: There are many applications that require a moderate
amount of power (W to kW) to be switched on and off fairly
rapidly. A good example would be the operation of a heater
element in a controlled-temperature system. Typically, the
amount of heat put into the system is regulated using pulse-
width modulation turning a fixed-power heating element on
and off for time periods ranging from seconds to minutes.
Mechanical relays have a finite cycle life, as their components
tend to wear out over thousands to millions of cycles. SSRs do
not have this problem; in the proper application, they could
be operated almost infinitely.

Q : What are the limitations of using an SSR?
8-Amp
A: SSRs have a few limitations when compared to the
capabilities of their mechanical counterparts. First, because
the relay is semiconductor-based, it will never turn all the way
on, nor off. This means that in the “on” state, the relay still has
some internal resistance to the flow of electricity, causing it to
get hot. When in the “off” state, the relay will exhibit a small
amount of leakage current, typically a few mA. This leakage
can conspire to keep some loads, especially ones with a high
impedance, from turning off! Additionally, SSRs are more
sensitive to voltage transients; while Opto 22 relays are very
well transient-protected, if a relay gets hit hard enough a
sufficient number of times, it will die or degrade. This makes
SSRs less ideal for driving highly inductive electromechanical
loads, such as some solenoids or motors. SSRs should also
never be used for applications such as safety power

.25 ohm 150 W .5 ohm 150 W

disconnects, because even in the off state, leakage current is
present. Leakage current through an SSR also implies the
presence of a potentially high voltage. Even though the relay
is not conducting a large amount of current, the switched
terminal will still be “hot,” and thus dangerous.

Solid-State Relays
Q : Do you make multi-pole or multi-throw SSRs?
voltages and currents. Use a mechanical relay; it will work
much better.
A: Opto 22 manufactures only single-pole, single-throw SSRs.
If multi-phase operation is required, just use a relay on each
phase. Because of the limitations on semiconductor devices of
the type used in SSRs, it is not practical to build single-device
multi-throw SSRs. However, an alternative to multi-throw
operation may be accomplished with multiple relays.
Q : What agency approvals do your SSRs carry?
A: In general, Opto 22 relays carry UL, CSA, and CE approval.
See http://support.opto22.com. Additionally, some SSRs
contain VDE-approved optocouplers; contact Opto 22 for
more information.
Q : Can I hook up SSRs in parallel to achieve a higher
current rating?
FAQ: SSR Troubleshooting
A: No. There is no way to guarantee that two or more relays
will turn on simultaneously when operated in parallel. Each
relay requires a minimum voltage across the output terminals
to function; because of the optical isolation feature, the
“contact” part of the SSR is actually powered by the line it
switches. One relay turning on before the other will cause the
second relay to lose its turn-on voltage, and it won’t ever turn
on, or at least not until the first relay fails from carrying too
much current.
Q : My SSR does not function anymore. What may
have happened?
A: There is no “normal” mode of failure for SSRs. They just stop
working, by refusing to turn on or off. An improper installation
is often to blame for an SSR failure, as these are very simple,
reliable devices. If you have a failed SSR, it is important to look
at the normal operating parameters of that relay within the
larger system to make sure that the relay being used is
appropriate to the application, and that the relay is being
properly installed in the system. The three most common
causes of SSR failure are as follows:
Q : What does a “zero-crossing” turn-on circuit refer
to?
A: An AC sine wave will be positive for the first half of each
cycle and negative for the second half of each cycle. The
voltage will cross through zero when the sine wave changes
from the positive half-cycle to the negative half-cycle, and vice
versa. So the voltage crosses through zero twice with each full
AC sine wave cycle. “Zero-crossing” turn-on means that the
SSR will only turn on when the AC sine wave passes through
zero voltage. The actual turn-on will occur at or near zero
voltage. All Opto 22 AC output solid-state relays are designed
with a zero-crossing turn-on circuit. Zero-voltage turn-on has
the benefit of minimizing electrical noise. All Opto 22 AC
output solid-state relays use a zero-current turn-off circuit as
well.
•
SSR improperly matched to load. The relay was
destroyed by overheating from carrying too much
current too long.
•
SSR insufficiently protected. Remember, a
semiconductor is less tough than a simple metal contact.
Reverse voltages exceeding the PRV rating of the relay
will cause damage. Voltage spikes on the switched line,
perhaps from inductive kickback, may have destroyed
one or more of the internal switching devices.
Remember to use snubbers, transorbs, MOVs, and/or
commutating diodes on highly inductive loads.
•
SSR improperly installed. The SSR was not mounted to
a large enough heat sink, or no thermal compound was
used, causing the relay to overheat. Also, insufficient
tightening of the load terminals can cause arcing and
ohmic heating of the relay. Opto 22 recommends 18
inch-pounds of torque on the load screw terminals.
Similar failures have also been attributed to the use of
crimp-on terminal lugs or spades; make sure such
terminals are tightly crimped, and even drip some solder
into the joint to ensure good electrical contact and
protection from corrosion.
Q : Can I use an AC SSR to switch DC?
A: No. Because of the zero-crossing circuit described above,
the relay will most likely never turn on, and even if it is on, it
will most likely not be able to be turned off.
Q : Can I use a DC SSR to switch AC?
A: No. The semiconductor device used in Opto 22’s DC SSRs is
polarized. It may break down and conduct for the portion of
the waveform that is reversed in polarity.
Q : How can I test my SSR?
Q : Can a DC SSR be used to switch an analog signal?
A: It is not possible to test an SSR by the same methods used
to test mechanical relays; a typical SSR will always show an
infinite impedance to a resistance meter placed across the
output terminals. There are a few reasons for this. First, the SSR
A: This is not recommended at all. First, the voltage drop across
the relay will cause signal loss. Second, the conduction
characteristics of the SSR are very non-linear at low operating

Solid-State Relays
requires a small amount of power to operate, derived from
whatever voltage source is placed on the load terminals. A
typical multimeter will not supply sufficient voltage to cause
the relay to change state. Second, AC SSRs contain zero-
voltage turn-on and zero-current turn-off circuits. The SSR will
not be able to turn on unless there is AC voltage connected to
the output terminals. Most test equipment will supply a DC
voltage to the relay, so it will never see the zero-voltage
transition it requires to turn on. To test an SSR, it is best to
operate it at the actual line voltage it will be used at, driving a
load such as a large light bulb.
Q : I have an SSR driving a load. The load turns on
okay, but never seems to turn off, unless I remove
power from the relay entirely. What might be hap-
pening?
A: This is normally a problem when using an SSR with a high-
impedance load, such as a neon lamp or a small solenoid.
Loads like these often have relatively large initial currents, but
relatively small “hold in” currents. The result is that the off-state
leakage current through the relay (see previous section) is
insufficient to cause the load to turn on to start with, but
sufficient to keep it on, once started. The solution is to place a
power resistor, sized for 8–10 times the rated maximum
leakage current for the SSR in parallel with the load. Make sure
that this resistor has a high enough power rating for the
application. For example, for a 5 mA leakage current at 120
VAC, a resistor drawing 50 mA would be desirable. Using
Ohm’s Law, the resistor value becomes 2,400 ohms. This
resistor will dissipate 6 watts, so a 7.5 or 10-watt size power
resistor should be used.
Q : I have a new AC SSR driving a solenoid. It turns on
okay once, but will not turn on again. What is going
on?
A: Some solenoids, some types of halogen lights, and some
types of strobe lights incorporate a diode in series with the coil
or filament. This causes the light to behave as a half-wave
rectifier. Opto 22 SSRs have a built-in R-C snubber circuit in
parallel with the output. The capacitor in this circuit charges
up but cannot discharge through the series diode, causing a
voltage to appear across the SSR terminals. Because the SSR
must detect the AC waveform cross through zero volts on the
load terminals, it will not be able to turn on again. The solution
here would be to put a high-value resistor (several tens of
Kohms) across the terminals of the relay, to allow the capacitor
to drain its charge.
