Short description

The BL 210/B (CANopen) and the BL 27x/x series are bus coupler modules that, in combination with I/O

modules, enable the decentralization and transmission from module islands.

The BL 27x/x series is used as a bus coupler between EtherCAT and K-bus. Modules of the system can

thereby be operated as remote I/O islands. The BL 27x/x can be connected to a control via EtherCAT and

is thereby made an EtherCAT slave. Two variants of the BL27x series are available:- With four additional

digital inputs (BL 27x/A)- With four additional digital outputs (BL 27x/B)

As a special feature, the BL 272/x enables the connection of interface modules for fieldbuses (FM 200/A)

and serial in terfaces (SM 210/A, SM 220/A, SM 230/A). This enables the operation of such interfaces

remotely from CPU modules.

This feature is also referred to as “bus via bus communication”.

The status of the module is indicated via a status LED. The LEDs on the RJ45 sockets provide information

about the link and activity status of the respective network connection. Each digital input/output also has

a status display (active/ not active).

These modules are attached directly to a CPU module or can be operated with all KEBA controls by means

of bus couplers.
