AA/S4.1.2 ABB i-bus KNX Analogue Actuator 4-Fold MDRC 0-10V or 0(4)-20mA HVAC Valve and VAV Module
The ABB i-bus KNX AA/S 4.1.2 is a four-channel analogue actuator in a modular DIN-rail housing (MDRC). It converts KNX telegrams into industry-standard analogue output signals, creating a direct electrical interface between the bus installation and third-party HVAC hardware.
Each of the four outputs can be parameterised for 0...10 V DC voltage control or for 0(4)...20 mA current control, enabling proportional positioning of continuous actuators such as valve drives, damper motors, VAV terminal units and electronic fan controllers.
Commissioning is performed with ETS, while the ABB i-bus Tool adds parameter diagnosis and faster start-up on site.
