Description

SNAP I/O analog input modules are part of

Opto 22’s SNAP PAC System. All of these

modules mount on a SNAP PAC rack with a

SNAP PAC brain or R-series controller, either

a standard wired model or a

A minimum number of SNAP module types

support a full range of analog input

requirements. These software-configurable

modules handle a wide variety of signal

levels. They provide high resolution (0.004%

of nominal range) for precise signal levels, as

well as multiple-channel packaging. All

SNAP analog modules are factory calibrated

and individually tested. Part numbers

ending in -FM are Factory Mutual approved.

SNAP analog input modules have an on-

board microprocessor to provide module-

level intelligence, which makes them an

ideal choice for Original Equipment

Manufacturers (OEMs). For additional

information about the standalone operation

of SNAP analog modules, see Opto 22 form

#0876, SNAP I/O Module Integration Guide.

Notes for legacy hardware: Some of these

modules also work with older Opto 22 I/O

processors (brains or on-the-rack

controllers) and M-series or B-series racks. To

check processor compatibility, see the table

on page 3.

Specifications begin on page 4. For

dimensional drawings, see pages 35–45.

IMPORTANT: Any system using analog

sensors and input modules should be

calibrated annually for analog signals. For

I/O units on a SNAP PAC System, use the PAC

Offset” and “Calculate and Set Gain.” For

other Ethernet-based I/O units, you can also
