B&R Industrial Automation X20DI6371 DC Input Terminal Block

The X20DI6371 is a six‑channel digital input module in B&R's X20 I/O system, delivering six 24 V DC inputs for 1‑ or 2‑wire wiring configurations. It supports sink inputs and wires through X20 terminal blocks, with the X20 6‑pin terminal block available for universal 1‑line wiring. The module draws 0.15 W from the backplane bus and 0.88 W for its own I/O, and provides per‑channel LEDs and diagnostics in the software for quick status checks. It is CE and UKCA marked with UL/cULus listings and carries hazardous‑location approvals (ATEX Zone 2, II 3G Ex nA nC IIA T5) as well as process control equipment certifications; IP20 enclosure with Ta operating range applies to standard X20 devices. In practice, the DI6371 is used to monitor digital sensors, switches, and other 24 V DC inputs in automated machinery, feeding reliable real‑time input data to the control system via the X20 bus. This module integrates with B&R Automation Studio for configuration, diagnostics, and online monitoring, enabling scalable expansion of centralized I/O across industrial applications.
