B&R X20DI8371 Digital Input IO Module

X20DI8371 is an eight‑channel digital input module for BR’s X20 I/O system. It provides eight 24 VDC digital input channels in a sink configuration for 1‑wire field connections, with a software‑configurable input filter that applies to the entire module to help reject EMI and noise. Designed to pair with the X20BM11 bus module, the unit accepts 24 V signals with a voltage tolerance of -15% to +20% and is specified for rugged industrial environments, including a transport temperature range from -40 to 85°C. This module is commonly used to read 24 V sensors such as proximity switches, limit switches, and pushbuttons in distributed automation layouts, enabling straightforward expansion of a BR X20 I/O system without impacting controller logic.
