Allen-Bradley 1762-IR4 4-Point RTD Input Module

Allen-Bradley 1762-IR4 is a four-channel RTD input module designed for MicroLogix controllers, providing four RTD temperature input channels for monitoring thermal processes in automation systems. It mounts on a DIN rail and communicates via the MicroLogix expansion I/O bus, compatible with MicroLogix 1100, 1200, and 1400 controllers. The module supports RTD sensors (Pt100, Pt200, Pt500, Pt1000 depending on configuration) and offers high-resolution temperature measurement across an operating range of 0°C to 55°C. Typical applications include process control systems, HVAC equipment, food and beverage production lines, water treatment facilities, and general temperature monitoring in manufacturing. Common replacements include Allen-Bradley 1762-IF4, 1769-IR6, and Siemens 331-7PF01-0AB0.
