Belimo CM24-SR-F-T-R - modulating damper actuator

Belimo CM24-SR-F-T-R damper actuator

Modulating actuator designed to position dampers in technical building systems. According to the technical data sheet, it is intended for air dampers with an area of up to approx. 0.4 m². The analogue control signal Y determines the actuator position, while signal U enables electrical position feedback.

Key specifications

• Torque: 2 Nm; power supply: AC/DC 24 V, 50/60 Hz.
• Control range Y: 2...10 V; position feedback U: 2...10 V.
• Running time: 75 s / 90°; rotation angle: 95°, fixed setting.
• Motor direction of rotation: clockwise (cw).
• Power consumption during operation: 1 W; in the resting position: 0.5 W; for cable sizing: 1.5 VA.
• Mechanical connection: 8x8 mm form-fit connection; electrical connection: terminals.
• Manual override: using a magnet; mechanical position indicator.
• IEC/EN protection rating: IP20; IEC/EN protection class: III, Safety Extra-Low Voltage (SELV).
