B&R Industrial Automation X20DI6371 Digital Input Module

The B&R X20DI6371 is a six-channel digital input module for the X20 I/O system that provides 24 VDC digital inputs for 1- or 2-wire wiring. Its inputs are sink-configured and designed for direct connection of standard 24 V sensors and switches in industrial automation. A software-configurable input filter can be applied to the entire module to tailor debouncing and noise immunity to the application, improving signal reliability in electrically noisy environments. The X20DI6371 is part of the X20 digital input family and integrates with B&R controllers via the X20 bus architecture, enabling straightforward input acquisition for discrete signals and machine status monitoring. Typical use cases include reading the state of pushbuttons, limit switches, and other 24 V field devices, or consolidating multiple sensors into a single six-channel module for scalable input expansion within a B&R automation system.
