ABB Valve Drive Actuator, 12-fold, 230 V, MDRC

The Valve Drive Actuators VAA/S are modular installation devices in Pro M Design for installation in the distribution board on 35 mm mounting rails. The devices feature twelve semiconductor outputs for control of Thermoelectric Valve Drives in heating and cooling systems.

The outputs can be operated at 24-230 V AC.

The outputs are short-circuit and overload protected. The outputs can be directly controlled using the manual buttons. The LEDs on the front of the device signal the status of the outputs. The connection to the ABB i-bussÂ® KNX is implemented via a bus connection terminal.

The devices do not require an additional auxiliary power supply.
