LF 24-SR • Actuators with spring reset 4Nm modulating 0-10V

Servomotor with spring return for air volume safety dampers of up to 0,8 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 4 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

  • Clips for axle diameter 16 - 20 mm, type K6-1
  • Positioners, type SGA24 / SGF24

Technical data

  • Power consumption:
  1. In operation: 2,5 W @ nominal torque
  2. At rest: 1 W
  3. For wire sizing: 5 VA
  • Control:
  1. Control signal Y: DC 0-10 V, typical input impedance 100 kΩ
  2. Working range: DC 2-10 V
  • Position feedback (Measuring voltage): DC 2-10 V, max. 1 mA
  • Position accuracy: +/- 5%
  • Direction of rotation: reversible by mounting
  • Direction of rotation at Y = 0 V: at switch position 0 resp. 1
