The Weidmuller UR20-4AI-RTD-DIAG is a high-performance analog input module designed for the modular u-remote I/O system. It is specifically engineered for precise temperature measurement using a wide range of resistance temperature detectors (RTDs). This module features four channels, each capable of connecting to 2-, 3-, or 4-wire RTD sensors such as Pt, Ni, and Cu types. With a 16-bit resolution, it delivers highly accurate readings essential for process control and monitoring applications. Integrated diagnostic functions, including wire-break and short-circuit detection, enhance system reliability and simplify troubleshooting. Its slim 11.5 mm design saves valuable space in the control cabinet, making it an ideal solution for modern, compact automation systems.
