Beckhoff BK7420 RS232 Bus coupler

The Beckhoff BK7420 is a Fipio "Economy plus" Bus Coupler that connects the Fipio fieldbus system (based on the WorldFIP standard) to Beckhoff's modular Bus Terminal system (KLxxxx series). It allows a station consisting of the coupler, up to 64 Bus Terminals, and an end terminal to function as a Fipio slave, with the coupler automatically recognizing connected terminals and activating the relevant transfer profile.
