A-B 1746-NT8 Module Overview SLC500 Thermocouple/mV Analog Input Module

General Description

This module mounts into 1746 I/O chassis for use with SLC 500 fixed

and modular systems. The module stores digitally converted

thermocouple/mV analog data in its image table for retrieval by all

fixed and modular SLC 500 processors. The module supports

connections from any combination of up to eight thermocouple/mV

analog sensors.

Input Ranges

The following tables define thermocouple types and associated

temperature ranges and the millivolt analog input signal ranges that

each of the module’s input channels support. To determine the

practical temperature range of your thermocouple, refer to the

specifications in Appendix A.

Each input channel is individually configured for a specific input

device, and provides open-circuit, over-range, and under-range

detection and indication.
