Theben KNX 1 Channel Shutter Actuator – Flush-Mounted (JU 1 KNX)

The Theben JU 1 KNX is a 1-channel flush-mounted blind/switch actuator with KNX Data Secure. It controls drives for blinds, roller shutters, sun and privacy protection, skylights and ventilation flaps, and includes an integrated automatic ventilation function. Alternatively it can be configured as a 2-channel switch actuator. Two binary inputs accept potential-free contacts such as push buttons, switches or window contacts (temperature sensor on I2); out of the box they are assigned to the output for testing before programming. Integrated temperature monitoring adds operating safety, e.g. on overload. Technical data: KNX bus current <4 mA; switching capacity max. 10 A per device at 230 V AC; incandescent/halogen load 800 W; ambient temperature -5 °C to 45 °C.
