Design with the communication and power supply unit
Design with communication and power supply device BKNE 230-24 and with actuator BEN 24-ST.
The BKNE 230-24 serves on the one hand as a decentralized network device for powering the
actuator and on the other hand transmits the signal of the communication and control device
BKSE 24-6.
It simplifies electrical installation and connection of dampers. In the meantime, it facilitates “on-site
inspection” and allows central control and inspection of dampers using a simple 2-wire line.
The BKNE 230-24 transmits the "OPEN" / "CLOSED" damper position (switches in the actuator)
and fault messages to the BKSE 24-6. It also receives commands from the control device and
controls the adjustment of the actuator to the desired position. The last control command will be
retained even after a temporary network failure..
The BKNE 230-24 controls the switching position of the actuator, its adjustment time and the data
exchange with the BKSE 24-6. In addition, it controls the actuator current (actuator connection) and
the power supply.
To simplify the connection, the actuator is equipped with plug connectors that plug directly into the
BKNE 230-24.
The actuator, communication and power supply device BKNE 230-24 are mounted in an insulated
cover, they are accessible after removing the cover. The electrical connection of the actuator and
the BKNE 230-24 communication and power supply device is made with a non-flammable cable
(or a cable located in an adjoining cable duct), the two-wire BKNE 230-24 cable should be
connected to terminals 6 and 7. It is also recommended to use cable, which is used for fire
signalling network. The cables pass through an opening made in the wall of the insulated cover
when installing the damper or when connecting the actuator power cable. The cable entry must
meet a minimum fire resistance of 30 minutes.
For more information on actuators and devices, see the Belimo catalogue.
