MDT - Switch Actuator 16-fold, 8SU MDRC, 230VAC, 16A, C-Load 140uF

Description

The MDT Switch Actuator receives KNX/EIB telegrams and switches up to 24 independent electrical loads. Each output
uses a bistable relay and can be manually operated by a push button. A green LED indicates the switching status of each
of each channel. The MDT switching actuator is suitable for high inrush currents and used for heavy loads (C-Load).
The outputs are individually parameterised via ETS. The device offers extensive functions such as logic operation, status
block functions, central function, delay functions and staircase lighting function. In addition, the device allows various time and scene controls. In the event of a bus voltage failure, all outputs retain their current position. After the bus voltage has failed or has been restored, the relay position
or restoration, the relay position is selected according to the parameterisation.
