Belimo NF24A-MP – actuator for dampers

A communicative rotary actuator with a fail-safe function for controlling dampers in technical building systems. It can operate with an analogue control signal or receive a digital signal via MP-Bus. In analogue mode, feedback signal U indicates the damper position; during bus operation, connection U is used for communication and does not provide an analogue measuring voltage.
