NF 24A-SR • Actuators with spring reset 10Nm modulating 0-10V

Servomotor with spring return for air volume safety dampers of up to 2 m² depending on the type of air valve and the pressure on the valves. Simple direct mounting on the damper axe with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating.

Brand

  • Belimo

Application

  • Safety dampers

Specifications

  • Torque 10 Nm
  • Nominal Voltage 24 V AC / DC
  • Control: modulating standard control signal DC 0-10 V, position feedback DC 2-10 V. The measuring voltage U allows the damper position (0-100%) to be electrically indicated and serves as a follow-up control signal for other actuators

Accessoires

  • Positioners, type SGA24 / SGF24
