Belimo CM24-SX-R - modulating damper actuator

Belimo CM24-SX-R damper actuator

This modulating actuator is designed to position dampers in technical building systems. According to the technical data sheet, it can operate air dampers with an area of up to approx. 0.4 m². The Y control signal determines the actuator position, while the U feedback voltage is used to electrically indicate the damper position.

Key features and specifications

• Motor torque: 2 Nm; rated voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Operating range Y: 2...10 V; position feedback signal U: 2...10 V.
• Motor running time: 75 s / 90°; motor rotation direction: clockwise (cw).
• Rotation angle: 0...287.5°; angle adjustment using mechanical end stops.
• Manual adjustment using a magnet; setpoint range adaptation triggered by a magnet, automatic on first power-up.
• Mechanical connection: universal shaft clamp for 6...12.7 mm shafts; power and control connection: 1 m cable, 4x 0.75 mm².
• Power consumption during operation: 1 W; in idle position: 0.5 W; power for cable sizing: 1.5 VA.
