Product Description:

The 00.C6.CB1-0200 bus coupler is engineered by KEB and belongs to the C6 Combicontrol Bus Couplers series. It forms the interface between distributed digital I/O racks and a higher-level controller, translating the local signal array into a real-time fieldbus telegram. In an industrial cell, this device allows sensors and actuators to report states or receive commands within microseconds, so motion, safety, and process events remain synchronized without installing a full PLC at every cabinet. That arrangement lets a centralized controller monitor remote devices while keeping cabinet layouts compact.

This coupler communicates over the EtherCAT network at a fixed line speed of 100 Mbit/s, and protocol handling is executed by the Beckhoff-designed ET1100 ASIC integrated on the board. The unit provides 32 opto-isolated digital inputs, letting a single slice capture a byte-wide conveyor encoder, multiple limit switches, or other discrete field signals. The internal E-bus continues downstream through a 10-pin system plug, while supply conductors are grouped in a dedicated 36-pole power connector to simplify daisy-chain assemblies. This layout keeps signal distribution and power routing organized across the terminal stack. The housing has no I/O status LED or power LED, so status indication is handled through the supervisory software instead of on the front panel.

Within the backplane, the module loads the common rail with 85 mA, so several neighboring terminals can be operated before system power budgeting becomes critical. The module uses no secondary feed-in connection, and the design also omits a terminating module because the shielding and address logic are already built into the profile end cap. This reduces the number of auxiliary parts in the assembly and shortens installation time. Centralized diagnostics through the controller compensate for the missing panel LEDs during operation. The streamlined enclosure also keeps the front of the unit clear for dense installations.
