B&R X20CS2770
2 CAN bus interfaces for serial, remote connection of complex devices to the X20 system Integrated terminating resistors In addition to the standard I/O, complex devices often need to be connected. The X20 CS communication modules are intended precisely for cases like this. As normal X20 electronics modules, they can be placed anywhere on the remote backplane.
