Communication and control devices
indicates operating condition and faults of dampers. These conditions can be
signalled or transmitted to the higher-level control system via the auxiliary built-in contacts.
Signals from individual BKNE 230-24 are evaluated separately. All BKNE 230-24 are controlled
simultaneously. A maximum of 6 BKNE 230-24 can be connected to the BKSE 24-6.
Damper control is ensured with a simple 2-wire line. The damper's correct function is indicated by
two LEDs. The operating status of the entire control system and any errors are indicated by these
LEDs and the corresponding error LED.
Mounting and connection of BKSE 24-6 can be done on a 35mm DIN rail. It's connected using
two 9-pin terminal blocks (plug connectors).
