Product Overview

The 1769-IR6 is a high-precision analog input module designed for the Allen-Bradley CompactLogix and MicroLogix 1500 series. Featuring six isolated-to-bus channels, this module provides accurate temperature monitoring and resistance measurements in demanding industrial environments. It supports a wide array of RTD types and direct resistance configurations, making it essential for thermal processing, HVAC systems, and precision cooling applications.

With integrated diagnostic capabilities, the 1769-IR6 ensures system reliability by detecting hardware faults before they impact production.

Diagnostic and Performance Features

The 1769-IR6 provides comprehensive onboard diagnostics to maintain peak system performance. Each of the six channels monitors:

Open-Circuit Detection: Detects broken field wiring with response time as low as 6 ms.
Short-Circuit Detection: Protects the module and alerts the CPU if an input is shorted.
Range Indication: Visual LED and software bit alerts for Over-range and Under-range status.
Data Conversion: Analog signals are digitally converted and stored as 16-bit integers, easily scaled in Studio 5000 or RSLogix 500.

Mounting and Field Wiring

Removable Terminal Block (RTB): Allows module replacement without disturbing existing field wiring.
Sensor Support: Compatible with 2-wire, 3-wire, and 4-wire RTD configurations. (3-wire and 4-wire recommended for maximum accuracy over long cables).
Stability: Low power dissipation (1.5 W) reduces heat buildup, extending the life of adjacent components.

Common Technical Questions

Can I mix different RTD types on the same 1769-IR6 module?
Yes. Each channel is individually configurable. You can have a Pt100 sensor on channel 0 and a 1000 Ω resistance sensor on channel 1 simultaneously.
How does the 1769-IR6 handle cable resistance compensation?
With 3-wire or 4-wire sensors, the module automatically measures and cancels the resistance of the lead wires (up to 25 Ω per wire), ensuring the reading reflects only the sensor element's value.
