B&R Industrial Automation X20AT4222 Temperature Input Module for X20 System

The B&R Industrial Automation X20AT4222 is an analog temperature input module designed for integration within the modular X20 control and I/O system. Engineered for precise thermal monitoring in industrial automation architectures, this compact slice module provides four channels for resistance temperature detectors such as PT100 and PT1000 sensors. It operates within standard B&R PLC environments, communicating through X20 backplane bus modules to transfer high-resolution digitized sensor data to the central processing unit. The module features integrated sensor supply circuits, configurable filter times, and support for multi-wire RTD configurations to compensate for line resistance. Common applications include process temperature monitoring, heating control loops, plastics processing machinery, packaging lines, and environmental chambers. Designed for space-saving DIN rail installation when paired with compatible X20 terminal blocks and bus modules, the X20AT4222 delivers reliable performance across demanding industrial operating conditions.
