Belimo NR24A-KNX - rotary actuator for ball valves

Belimo NR24A-KNX rotary actuator

NR24A-KNX is a communicating rotary actuator for ball valves. Its integrated KNX (S-Mode) interface allows connection to KNX devices with the appropriate data points. The KNX application supports 2- and 3-way valves with one setpoint, and 6-way valves in 4-pipe systems with two setpoints for heating and cooling.
