B&R Industrial Automation X20AT6402 Temperature Input Module for X20 System

The B&R Industrial Automation X20AT6402 (X20AT6402) is a four-channel analog temperature input module designed for precision thermal monitoring in the B&R X20 System automation environment. This module is engineered to interface directly with resistance temperature detectors (RTDs), supporting both PT100 and PT1000 sensor types across 2-wire and 3-wire connection configurations. It translates analog resistance measurements into high-resolution 16-bit digital temperature values, providing accurate and stable feedback to X20 bus controllers and programmable logic controllers. Commonly deployed in packaging machinery, plastics processing, process automation, HVAC systems, and general industrial manufacturing equipment, the module facilitates reliable closed-loop temperature control. Operating with bus-powered internal electronics and galvanic isolation between the channels and the internal I/O bus, the unit ensures signal integrity and noise immunity in electrically demanding factory environments. The slice-based modular design mounts seamlessly on standard X20 terminal blocks and bus modules, allowing fast installation, pre-wiring, and hot-swappable module replacement during scheduled maintenance.
