BK7520 | SERCOS II Bus Coupler

The BK7520 Bus Coupler connects the SERCOS bus system with the electronic terminal blocks, which can be extended in modular fashion. One unit consists of one Bus Coupler, any number from 1В to 64В terminals and one end terminal. The BK7520 allows, with the K-bus extension technology, the connection of up to 255В Bus Terminals to one Bus Coupler. The Bus Coupler recognizes the connected terminals and automatically generates the affiliations of the inputs/outputs to the bytes of the process image.
