Beckhoff BK1120 RS232 Bus coupler

The Beckhoff BK1120 is an EtherCAT Bus Coupler that connects standard K-bus Bus Terminals (KLxxxx) to a 100BASE-TX EtherCAT network. It converts passing Ethernet telegrams into the internal, fieldbus-independent terminal bus, allowing a station consisting of the coupler, up to 64 Bus Terminals, and a bus end terminal to function as an EtherCAT slave.
