Allen-Bradley 1762-IR4 RTD Resistance Input Module

Allen-Bradley 1762-IR4 RTD Resistance Input Module provides RTD resistance signal conditioning and input acquisition for MicroLogix 1200 controllers, delivering precise temperature readings for industrial process control. It is rack-mounted in a MicroLogix chassis and connects via the backplane to the MicroLogix PLC, supporting multiple RTD channels with model-dependent configuration and 2-, 3-, or 4-wire RTD sensors for high-accuracy resistance-to-temperature conversion. Common applications include manufacturing production lines, water and wastewater facilities, food and beverage processing, chemical plants, HVAC temperature control panels, and material handling systems where dependable RTD sensing improves regulation, safety, and efficiency. Operating under industrial-rated conditions and installed within a control enclosure, this module serves as a dedicated RTD input solution for temperature measurement and process control.
