Built‑in function

X20DC4395 multi‑function counter module supports mixed configuration of SSI absolute encoder and 24VDC incremental encoders for X20 control system. It integrates event counting and PWM signal generation,realizes position acquisition,time measurement and pulse output in single module. 500Veff galvanic isolation enhances anti‑interference performance. Supports local X20 I/O and distributed X2X‑Link remote stations deployment.

Product Brief

X20DC4395 belongs to B&R X20 I/O system family,it is universal multi‑function counter module for complex motion measurement applications. X20BM11 bus module and X20TB12 terminal block need to be ordered separately. Shielded cables are required for encoder wiring. Widely used for original B&R automation equipment maintenance and renovation. Before purchase,please verify encoder type and function configuration requirement. ESD anti‑static protection shall be followed during installation
