- Provides four 24 VDC sink inputs with 3-wire sensor connections
- Allows each channel to operate as a 16-bit event counter up to 1 kilohertz
- Includes short-circuit-protected 24 VDC and GND connections for sensor supply
X20DI4371 is a B&R digital input and counter module designed for X20 System I/O stations.
It integrates the documented I/O channels, electrical behavior, diagnostics, and model-specific functions into a compact X20 station slice.
Before installation or replacement, verify the complete material number, sink or source topology, terminal and bus modules, field supply, wiring, software configuration, and installed-system requirements.
Availability, condition, price, and shipping time for X20DI4371 are confirmed during quotation.
