Belimo TMC24A - damper actuator

Belimo TMC24A – damper actuator

Actuator designed to regulate air dampers in building technical systems. According to the technical data sheet, it supports dampers with an area of up to approx. 0.4 m².

Key specifications

• Motor torque: 2 Nm.
• Nominal voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Control: Close/Open, 3-point.
• Motor running time: 35 s / 90°.
• Maximum angle of rotation: 95°; can be limited on both sides using adjustable mechanical limiters.
• Direction of movement selected by switch: 0 (counterclockwise) / 1 (clockwise).
• Manual override by push-button with lock; mechanical position indicator.
• Mechanical connection: universal shaft clamp for 6...20 mm shafts.
• Power and control connection: 1 m cable, 3x 0.75 mm².
• Power consumption during operation: 1.5 W; at rest: 0.2 W; sizing power: 2.5 VA.
• Degree of protection IEC/EN: IP54; protection class IEC/EN: III, Safety Extra-Low Voltage (SELV).
• Ambient temperature: -30...50°C [-22...122°F].

The actuator is protected against overload and stops automatically when it reaches the limiter. Direct mounting on the damper shaft is made using the universal clamp and an anti-rotation mechanism that prevents the housing from turning.
