Control module for maximum two damper actuators
CM24K-.. in technical building installations
SKM230-T-B12
Product features
The Power off reserve function characterises the behaviour of the controlled module
and/or the connected damper actuators in the event of an electricity interruption or
a power shutdown. It is guaranteed in such cases that the actuators will move into
Closed position, no matter which position they happen to be presently located at, at all
times and without manipulation. The storage energy loaded in the module during the
Opening function ensures this.
Mode of operation
The module SKM230-T-B12 can only be used with the appropriate air damper
actuators CM24K.. and works within the application with one or two actuators. The
compact design of the module makes it possible to install in hollow ceiling spaces or
raised floors - if needed up to 200 m away from the application.
Application
Electrical installation
• Caution: Power supply voltage!
• The module can also be operated with only one damper actuator.
