Compact coupler
January 1, 2008
Beckhoff’s BK1250 compact coupler acts as a seamless gateway between its original bus terminal I/O line and high-speed EtherCAT I/O terminals. The coupler converts EtherCAT’s E-bus signal so data can also be passed over Beckhoff I/O terminals (K-bus) on the same I/O node. No proprietary Fieldbus cards are required.
