B&R Industrial Automation X20DI2377G0 Input Module

The B&R X20DI2377G0 two‑channel digital input module for the X20 I/O system accepts 24 VDC signals on 3‑wire inputs in a sink configuration, making it suitable for field devices that switch to ground. It offers a software‑configurable input filter and two event counters up to 50 kHz, with built‑in I/O diagnostics and standard X20 bus interfacing through X20BM power modules and X20TB terminal blocks. Electrical characteristics include nominal 24 VDC input (−15%/+20%), bus power around 0.15 W and internal I/O consumption about 0.82 W, and broad certifications (CE, UL/cULus, UKCA, ATEX Zone 2 II 3G Ex nA nC IIA T5 Gc IP20) for operation in demanding industrial environments from 0 to 55°C.
