Product Brief

X20AT4222 belongs to B&R X20 I/O module family,it is four‑channel RTD temperature spare part,different from 2‑channel X20AT2222 module. Bus module and terminal block need to be ordered separately for field wiring. Widely used for original B&R automation equipment maintenance and renovation. Before purchase,please confirm X20 hardware version and backplane compatibility requirement. ESD anti‑static protection shall be followed during installation
