KNX 1-10V CONTROL UNIT 4 GANG

The control unit switches and dims electrical consumers with a 1-10 V interface (e.g. fluorescent lamps with electronic 1-10 V electronic ballasts, RGB-LED luminaires with integrated 1-10 V drivers). As an actuator, the control unit receives telegrams from push-button sensors, control panels or comparable controllers via the KNX and converts the received commands into switching or dimming actions. Dimming always takes place via variation of the 1-10 V voltage, provided by the consumers, at the inputs E1...E4. The switching function is implemented by relay contacts at the outputs A1...A4. This switches the power supply of the consumers. 5 device configurations can be selected, causing the allocation of the 4 individually-controllable dimming channels to the switching outputs. This means that, optionally, 1-10 V dimming channels can be combined to execute a shared switching action, in order to implement different control tasks (e.g. 4 dimming channels act on a switching relay to activate an RGBW luminaire or 4 dimming channels act in pairs, each on one relay, to separate two load circuits). Relay outputs not allocated to any dimming channel can be used as freely acting switching actuator channels.
