The heating actuator has 6 thermoelectric valve drives for heating or cooling. Up to 4 valve drives can be connected to each output. The outputs are either switch activated (1 bit) or PWM signal (1 byte) activated. All outputs can be operated manually using push-button operation. Nominal voltage is AC 110-230 V, 50/60 Hz. Outputs are electronic AC 24 V / 230 V. Nominal current: 0.05-0.16 A. the actuator can be installed for Installation on DIN rails TH35 according to EN 60715 it has many software features such as Characteristics of valve drive (open/closed), PWM cycle time per channel, valve protection function per channel, etc. The device has 84module width, approximately 72 mm. The color of device is light grey.
