Belimo NF24A-SR – actuator for dampers

Modulating rotary actuator with a safety function for controlling dampers in building technical systems. According to the technical data sheet, it is designed for air dampers with an area of up to approx. 2 m². During operation, signal Y controls the damper position while the return spring is tensioned. An interruption to the power supply causes the damper to return to the safety position.
