Function Overview
The 1769-IR6 is a temperature input module specifically designed for CompactLogix and MicroLogix 1500 systems (based on the 1769 series). This module accepts resistance temperature detector (RTD) signals and converts them into digital values, enabling precise temperature monitoring and control.
Equipped with six independent input channels, it is particularly suited for applications requiring stable multi-point temperature measurement, such as process equipment, machine enclosures, and thermal monitoring systems.
Practical Usage Notes
The sensor type must be selected in the controller configuration.
A three-wire RTD connection is recommended for improved accuracy.
Shielded cables are advised in high-interference environments.
Ensure cold junctions are properly handled according to the RTD type.

Model-Specific FAQ
Common Problem
How many temperature sensors can the 1769-IR6 module process simultaneously?
This module supports up to six RTD sensors operating concurrently, with one sensor per channel.
Does it support both two-wire and three-wire RTDs?
Yes. Both wiring configurations are supported depending on accuracy requirements.
Which controller series can use this module?
It is compatible with CompactLogix systems and MicroLogix 1500 controllers utilizing 1769 I/O.
Do all channels require the same type of RTD?
No. Each channel can be independently configured within the controller software.
