VAA/S12.230.2.1
Valve Drive Actuator, 12-fold, 230V, MDRC
Product code:
2CDG110117R0011
For controlling thermoelectric valve drives in heating/cooling systems at 24...230 V AC. The outputs are protected against short circuits and overload and can be switched via manual push buttons during commissioning.
Description
The Valve Drive Actuator VAA/S 12.230.2.1 is a modular installation device in Pro M Design for installation in the distribution board on 35 mm mounting rails. The devices features 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 KNX Bus is implemented via a bus connection terminal.
The devices do not require an additional auxiliary power supply
