MDT KNX relay module with current measurement 12x16A
355,37 € incl. VAT
The industrial version of the MDT Switch Actuator AKI for large to very large loads is used where particularly high inrush currents are to be expected. The actuator is equipped with bistable relays for currents up to 16/20 A and a C-load up to 200 µF. Thanks to mechanical manual operation, they are particularly suitable for sensitive areas. The channels can also be switched without bus voltage and the switching status is visible at all times.

The MDT Switch Actuator receives KNX/EIB telegrams and switches up to 12 independent electrical loads . Each output is switched via a bistable relay and can also be switched on the actuator by the mechanical manual control. The status of the switching channel is directly visible. The MDT Switch Actuator is suitable for extreme high inrush currents and used for heavy loads (C-Load). The outputs are set individually via ETS. The device provides extensive functions like logical operation, status response, block functions, central function, delay functions and staircase lighting function. Additionally the device provides several time and scene control. If the mains voltage fails, all outputs hold their current position. After bus voltage failure or recovery the relay position is selected in dependence on the settings. The MDT Switch Actuator has separate power supply terminals for each channel. It is a modular installation device for fixed installation in dry rooms. It fits on DIN 35 mm rails in power distribution boards or closed compact boxes.
