Built‑in function

X20DI4371 digital input module collects on‑site sensor switching signals for X20 control system. 3‑wire wiring provides local sensor power output,simplify field wiring work. Built‑in counter function realizes low‑frequency pulse acquisition without additional hardware. Adjustable software input filter suppresses field interference signals,galvanic isolation improves system anti‑interference capability. Channel‑level LED and software diagnosis realize fast fault positioning,support local X20 I/O and distributed X2X‑Link remote stations.

Product Brief

X20DI4371 belongs to B&R X20 I/O system family,it is 4‑channel sink digital input module with counter function for general automation equipment. X20BM11 bus module and X20TB12 terminal block need to be ordered separately. Widely used for original B&R automation equipment maintenance and renovation. Before purchase,please verify input signal type and counter frequency requirement. ESD anti‑static protection shall be followed during installation
