VNX-A module is compatible with VELUX® KMG100 window actuator drive. It allows interfacing the drive to a wide variety of an intelligent building systems (i.e. KNX, LCN, Loxone, MODBUS)

The control of the module is very simple and uses a pair of wires only. Depending on the applied power polarity, the VNX-A module closes or opens the window. The motion of the drive is constantly supervised by the module, which automatically switches off the drive after detection of the end position. This solution enables integration with any chosen intelligent building system - our module has already proven itself in such systems as KNX, LCN, Loxone or MODBUS.
