Specification

The Allen-Bradley 1769-IR6 is a high-performance RTD/Resistance input module designed for the CompactLogix platform, offering six fully isolated differential channels for accurate temperature sensing in demanding industrial processes. This module supports a wide range of RTD types (including Pt100, Pt1000, Ni100, and Cu10) and resistance measurements from 0 to 4000 ohms, making it versatile for both temperature and linear resistance applications. With 16-bit resolution and integrated diagnostics, the 1769-IR6 ensures reliable data acquisition for control systems in oil and gas, chemical, and manufacturing sectors. It communicates directly via the 1769 backplane without requiring additional wiring, and its compact form factor saves valuable panel space. The module is engineered for long-term stability and compliance with global safety standards.
