The Weidmüller UR20-4AI-RTD-DIAG Analog Remote Input Module is a part of Weidmüller’s UR20 series, designed for industrial  process control applications.

This  UR20-4AI-RTD-DIAG module provides a remote interface for acquiring analog signals from field sensors, specifically handling RTD (Resistance Temperature Detector) inputs and other standard analog input types. It is part of a distributed I/O system, ideal for systems that require remote monitoring and control of analog signals over long distances or in complex industrial environments.

The Weidmüller UR20-4AI-RTD-DIAG is an analog input module with a diagnostic feature that can interface with RTD sensors (for temperature measurement) and provide high-accuracy analog-to-digital conversion.
