B&R X20cCS1020

RS232 interface for serial, remote connection of complex devices to the X20 system In addition to the standard I/O, complex devices often need to be connected. The X20CS communication modules are intended precisely for cases like this. As normal X20 electronics modules, they can be placed anywhere on the remote backplane.
