Chapter 6
Temperature-measuring Analog Modules
(1756-IR6I, 1756-IT6I, and 1756-IT6I2)
Introduction
This chapter describes features specific to temperature-measuring
ControlLogix analog modules. These units linearize their respective sensor
inputs into a temperature value. The 1756-IR6I uses ohms for temperature
conversions and the two thermocouple modules (1756-IT6I, 1756-IT6I2)
convert millivolts.
These modules also support features described in
Chapter 3 . See the table for
some of these features.
