The BK1250 “Compact” Coupler acts as a bridge between Beckhoff’s original Bus Terminal I/O line and high speed EtherCAT Terminals for interoperability.
Configured as a “Bus Coupler in a Bus Terminal housing,” it converts EtherCAT’s E-bus signal so that data can be passed over Beckhoff I/O terminals (K-bus) on the same I/O node. You can now more easily integrate the more than 300 terminal variants within the Beckhoff Bus Terminal and EtherCAT I/O systems without having to separate I/O types on different nodes.
Bus Terminal I/O and EtherCAT I/O appear to be nearly identical from the outside and in terms of mechanical configuration. The differences are in the internal circuitry and signal processing. EtherCAT Terminals are specially designed for the highest Industrial Ethernet speeds and most flexible topology options.
The real-time EtherCAT protocol processes 1,000 distributed I/O in 30 µs or 100 axes in 100 µs using twisted pair or fiber optic cable. EtherCAT also delivers large network size (65,000+ devices) and a variety of flexible and time-saving cabling topology options.
