B&R Industrial Automation X20AT2402 IO Module

The X20AT2402 is a two‑channel thermocouple input module for the B&R X20 I/O system, designed for precise temperature measurement in industrial control cabinets. It provides two thermocouple inputs that support Type J, K, N, S, B and R sensors, each mapped to a 16‑bit ADC with an INT output format and software‑diagnostic capability. Configurable filter time ranges from 1 ms to 66.7 ms, with conversion times of 80.4 ms for a single channel and 120.6 ms for two channels when using a 50 Hz filter, allowing a balance of speed and noise rejection. Power consumption is specified as 0.72 W for internal I/O and 0.01 W for the bus, and the module is identified in software by the B&R ID‑code 0x1BA8. Housed for cabinet I/O in the X20 system, the X20AT2402 carries multiple international certifications (CE, UKCA, UL/cULus, ATEX Zone 2 II 3G Ex nA nC IIA T5 Gc IP20, among others) and is designed for integration with B&R software to support diagnostics and monitoring of temperature‑critical processes, such as heat treatment, furnaces, and other industrial temperature‑monitoring applications.
