Valve drive actuator with control, REG. SpaceLogic KNX valve drive actuator. Designed for controlling electrothermal valve drives for heating or cooling ceilings. The valve drive controller has 6 electronic outputs. Up to 4 valve drives (230 V AC) or 2 valve drives (24 V AC) can be connected to each output. Both normally closed and normally open valve drives can be connected. Additionally, the valve drive controller includes 6 integrated room temperature controllers (RTC) that operate independently. The control output signals from these RTCs can be internally linked to the valve outputs, allowing temperature control and valve operation to be managed by a single bus participant if needed. In this case, no external room temperature controller is required. Since the valve outputs can be controlled individually, the use of an external RTC is always possible. The integrated room temperature controllers can send the control signal to the bus, thereby controlling other heating actuators or fan coil actuators. The outputs are activated either by switch (1 Bit) or PWM signal (1 Byte). Each output is overload and short-circuit protected. All outputs can be manually operated via button control. Site operation is possible. Designed for mounting on DIN rails TH35 according to EN 60715. Bus connection is made via a bus connection terminal.
