KEBA PS244 Power Supply Module

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 ope

rated 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.

SM 210/A and SM 230/A are serial interface modules and enable the connection of two RS 232-C or RS 422/485-A

serial interfaces. The two communication channels function independent of one another in full-duplex operation.

SM 220/A is a serial interface card. This module enables the connection of a serial 20 mA Current Loop interface. The

interface functions both for the transmitter as well as for the receiver in active or passive operation. DIP switches are

provided on the front for switching the operating mode. At a maximum transmission rate of 9.6 kbits/s, a line length of

up to 1.000 m is possible.
