gain.

and below zero. An example of this is the SNAP-AIV module,

which has a range of -10 to +10 VDC.

Some modules are considered unipolar, which means the

range starts or ends at zero. For example, the SNAP-AIVRMS

module has a range of 0 to 250 VAC because AC current

cannot be negative.

Isolation

All SNAP analog input modules are isolated from all other

modules and from the SNAP I/O processor. The modules in

this data sheet do not have channel-to-channel isolation,

however. (If you need isolated analog modules, see Opto 22

form #1182.)

Nominal Range and Over-range Limits

All SNAP analog input modules have a nominal range for the

field signal and most support a 10% over-range limit. The

nominal range is the normal range of the field signal for the

module or point configuration. The over-range limit is the

maximum valid field signal the module or point configuration

can read outside of the nominal range. For example, the over-

range limits for the SNAP-AIV are -11 and +11 VDC, and for the

SNAP-AIVRMS, the over-range limit is 275 VAC.

Transformer isolation prevents ground loop currents from

flowing between field devices and causing noise that

produces erroneous readings. Ground loop currents are

caused when two grounded field devices share a connection,

and the ground potential at each device is different.

Isolation also protects sensitive control electronics from

industrial field signals.

Some modules or point configurations do not support field

signals outside of the nominal range. For example, points

configured as temperature inputs (thermocouple, RTD, ICTD)

do not support over-range readings.

IMPORTANT: Since these analog input modules provide

multiple single-ended input channels with a common

reference, the channels are not isolated from each other. (See

Opto 22 form #1182 for isolated modules.)

When the field signal is outside of the over-range limits of the

module, the brain will not be able to determine if the value is

too high or too low, so it will return an "out of range" value of -

32768.0

Bipolar and Unipolar Input Modules

Most SNAP analog input modules are considered to be

bipolar, which means the range extends equal amounts above

Over-range limits only apply to input modules. Output

modules are limited to their nominal ranges.

are right-side up, with zero on the left, as shown in the

diagram above. (If your rack has screw connectors, the

screw connectors will be at the bottom.)

fibus); B3000-HA; B6

2. Position the module over the module connector,

aligning the small slot at the base of the module with

the retention bar on the rack. When positioning modules

next to each other, be sure to align the male and female

module keys at the tops of the modules before snapping

a module into position.

All modules can be used with SNAP PAC rac ks and can be

placed in any position on the rack. Two- and four-channel

modules (except the SNAP-AIRTD-10 and SNAP-AIRTD-1K) can

also be used with legacy SNAP M-series and B-series

mounting racks. (For more information on using legacy

hardware, see form #1688, the SNAP PAC System Migration

Technical Note.)

3. With the module correctly aligned, push on the module

to snap it into place.

Modules snap securely into place in the row of connectors on

the mounting rack. Each module connector has a number.

Analog input modules and other types of SNAP I/O modules

are mounted on the module connectors starting at module

position zero.

4. (Optional) Use standard 4-40 x 1/4 truss-head Phillips

hold-down screws to secure both sides of each module.

CAUTION: Do not over-tighten screws.

5. Follow the wiring diagrams beginning on page 4 to

attach modules to the devices they monitor. Most

modules accept 22 to 14 AWG wire; the SNAP-AITM-8

accepts a maximum of two solid 18 AWG wires.

Modules require a special tool (provided) for removal.

For faster, easier field wiring installation and maintenance,

use SNAP TEX cables and breakout boards. See Opto 22 form

#1756, the SNAP TEX Cables & Breakout Boards Data Sheet, for

compatibility and specifications.

Variable resistance device

SNAP PAC brains and PAC Control provide direct temperature

readings for four popular thermistors using the Steinhart-Hart

equation (see page 16). You may also enter custom

coefficients for unsupported thermistor curves.

The simple two-wire connections are made to the pluggable

terminal strip on top of the module.

IMPORTANT: The mounting rack connector has 24 pins; the module

connector has 20 pins. The extra pins on the mounting rack

connector prevent misalignment of the module during installation.

NOTE: The eight input channels must be electrically isolated from

each other and earth ground. The transducer resistor element

must be isolated from any electrically conducting probe tube

housing.

Description

The SNAP-AIR400K-8 module has eight channels of analog to

digital conversion that convert resistance to temperature or to

Ohms. The module is ideal for NTC thermisters commonly used

in HVAC, refrigeration, and process control applications. It may

also be used with PTC thermisters in resistance sensing

applications. See the table on page 3 for I/O processor

compatibility.

See page 15 for module specifications.

Wiring Information

Unshielded 24 AWG wire (minimum) is recommended.

SNAP Analog Input Modules

Thermistor Input Module 0–400 K (continued)

Choose a 2-wire thermistor value with a resistance over the

target temperature range that is much larger than the lead

resistance for your application

Auto-range Curves

The following table shows temperatures in °C and °F that

correlate with resistance values in Ohms for the generic curve

types for four popular thermistors using the Steinhart-Hart

equation. Choose the curve type for your application in

PAC Control or PAC Manager when you configure a SNAP-

AIR400K-8 module.

Lower value curves (2252 or 3K) work best at cooler

temperatures (< 25 °C or 77 °F) because long lead wire

resistance can add significant errors to the measurement.

SNAP-AIRTD-1K Two-channel 1000 ohm platinum RTD input

SNAP-AIRTD

Two-channel 100 ohm platinum RTD input

SNAP-AIRTD-10 Two-channel 10 ohm copper RTD input

Wiring

RTD input modules are designed for three-wire connections,

shown in the diagram below.

If you use a four-

wire connection

(shown at the

bottom right),

DO NOT connect

the fourth wire,

as it will cause

errors in the

readings.

Two-wire

connections

are not

recommended,

as they will

degrade

accuracy and

stability.

IMPORTANT: The mounting rack connector has 24 pins; the

module connector has 20 pins. The extra pins on the

mounting rack connector prevent misalignment of the

module during installation.

Description

The SNAP-AIRTD and SNAP-AIRTD-1K platinum and the

SNAP-AIRTD-10 copper modules are usually used for

temperature inputs. They can also be used to make high-

resolution resistance measurements.

On all three modules, the two inputs share the same

reference terminal. Make sure you use isolated RTD probes.

The SNAP-AIRTD-10 and SNAP-AIRTD-1K require a SNAP

PAC brain or R-series controller.

SNAP PAC Brains

While SNAP PAC controllers provide central control and data

distribution, SNAP PAC brains provide distributed intelligence for

I/O processing and communications. Brains offer analog, digital,

and serial functions, including thermocouple linearization; PID

loop control; and optional high-speed digital counting (up to 20

kHz), quadrature counting, TPO, and pulse generation and

measurement.

Founded in 1974, Opto 22 has established a

worldwide reputation for high-quality products.

All are made in the U.S.A. at our manufacturing

facility in Temecula, California. Because we

test each product twice before it leaves our

factory, rather than only testing a sample

of each batch, we can guarantee most

solid-state relays and optically isolated I/O

modules for life.

SNAP PAC Controllers

Programmable automation controllers

(PACs) are multifunctional, modular controllers based on open

standards.

Opto 22 has been manufacturing PACs for over two decades. The

standalone SNAP PAC S-series, the rack-mounted SNAP PAC R-

series, and the software-based SoftPAC™ all handle a wide range

of digital, analog, and serial functions for data collection, remote

monitoring, process control, and discrete and hybrid

manufacturing.
