OUTPUT SPECIFICATIONS
■ Control Output: SSR (zero-crossing); 20 - 240 V AC 0.1 -
Low Voltage Directive
EN 61010-1, EN 61010-2-201
1 A
Measurement Category II (control output)
Pollution degree 2
Leakage current at OFF: Approx. 10 mA @ 240 V AC
Output operation at loss of communication: When a
communication error occurs in the middle of an output
operation, the operation continues toward until reaching
target position most recently set by Host device.
Position feedback 1 or position feedback 2 to control
output 1 to control output 2: Reinforced insulation (300 V)
RoHS Directive
FUNCTIONS
• SSR (Solid State Relay)
Output Operation: (terminal No. in parentheses)
Deadband
0
▼
SSR consists only of semiconductor elements, and thus SSR
is free from arc discharge and chattering which are typical
with electromagnetic relays.
(2 – 11) ON to min.
–
(1 – 11) ON to max.
+
Deviation
SSR has excellent durability against vibration, physical
impact, and environmental influences.
• Zero-Cross Function
Deadband
0
(7 – 16) ON to min.
–
(6 – 16) ON to max.
+
▼
Deviation
SSR with zero-cross function turns on when AC power
voltage is near zero.
When input is provided in the middle of a wave cycle, SSR
delays switching until the next time the voltage becomes
near zero, thus limiting transient switching noise voltage
and rush current.
INSTALLATION
Operating temperature: -10 to +55°C (14 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Atmosphere: No corrosive gas or heavy dust
Mounting: Installation Base (model: R3-BSx)
Weight: 190 g (0.42 lb)
PERFORMANCE
■ POSITION FEEDBACK INPUT
Conversion accuracy: ±0.4 %
The conversion accuracy is defined against the
potentiometer's full span.
Conversion rate: 10 msec.
Data range: 0 – 1000
Data allocation: 4
Current consumption: Approx. 50 mA
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F)
Temperature coefficient is defined against the
potentiometer's full span.
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength:
2000 V AC @1 minute (control output 1 to control output 2
to position feedback 1 or position feedback 2 or internal bus
or internal power)
2000 V AC @1 minute (power input to FG; isolated on the
power supply module)
