B&R Industrial Automation X20DI9371 Digital Input Module

The B&R X20DI9371 is a 12-channel digital input module for the X20 fieldbus I/O family that accepts 24 V DC signals via 1-wire connections. The inputs are sinking type, each channel has a per-channel LED indicator, and the device supports a software-configurable input filter that can be applied across the entire module to suppress noise and false triggers. Electrical ratings specify a nominal 24 VDC input with -15% to +20% tolerance and a typical input current of about 3.75 mA per channel; the module is designed for X20 systems and carries certifications including CE, cULus, cCSAus, with HazLoc Class 1 Division 2 and ATEX Zone 2 approvals. Common applications include digital signal acquisition from sensors and switches in automation, machine control, and process lines, where distributed 24 V signals need reliable, scalable I/O; the X20DI9371 integrates with other X20 modules to extend I/O capacity in industrial environments.
