Beckhoff BK7520 original Bus Terminal System

The Beckhoff BK7500 is a SERCOS II Bus Coupler that connects the SERCOS fiber-optic fieldbus system to Beckhoff's modular Bus Terminal system. It allows a station consisting of the coupler, up to 64 Bus Terminals, and an end terminal to function as a SERCOS slave, with the coupler automatically recognizing connected terminals and mapping I/O to the process image.
