Belimo VSF24A-LP1 - rotary actuator for dampers with safety function

Belimo VSF24A-LP1 – actuator for dampers

Rotary actuator with a safety function, designed for air dampers with an area of up to approx. 4 m². It can be controlled via Cloud, BACnet/IP or Modbus TCP. In hybrid mode, the position is determined by an analogue control signal, while the communication interfaces allow data points to be read.
