MDT - Switching actuator 16 times, 8SU MDRC, 230VAC, 16A, C-Load 140uF

description

The MDT Switch Actuator receives KNX/EIB telegrams and switches up to 24 independent electrical charges. Each exit
uses a bistable relay and can be manually operated by a push button. A green LED indicates the switching status of
each channel. The MDT switching actuator is suitable for high inrator currents and used for heavy loads (C-Load).
The outputs are parameterized individually via ETS. The device offers extensive functions such as logical operation, state
block functions, center function, delay functions and stair lighting function. In addition, the device allows multiple time and scene controls. In the event of a failure of the bus voltage, all outputs retain their current position. After the bus voltage fails
or redoing, the position of the relay is selected depending on the setting.
