MPN: BK1120 — industrial control spare part, in stock at TGK Parts.
The Beckhoff BK1120 is the classic EtherCAT bus coupler — the head unit of a Beckhoff terminal station that links the EtherCAT network to the K-bus extension bus. Tested used units are in stock.
It is one of the most widely deployed Beckhoff components in the field, which means spare demand is constant: when a coupler's network port or bus logic fails, the whole terminal station goes dark. A tested BK1120 restores the station without reconfiguring the terminal chain.
