SNAP Analog Input Modules

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.

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

Specifications begin on

drawings, see pages 28–36.

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 Control

commands “Calculate and Set Offset” and

“Calculate and Set Gain.” For other Ethernet-

based I/O units, you can also use PAC Manager

software to calculate and set offset and gain.
