Belimo LMQ24A-MF - actuator for dampers with analogue control

Belimo LMQ24A-MF is a configurable actuator for damper control in stationary heating, ventilation and air-conditioning systems. It is designed for air dampers with an area of up to approx. 0.8 m². Position is determined by the analogue control signal Y, while signal U provides position feedback.

Key features

• Motor torque: 4 Nm; supply: AC/DC 24 V, 50/60 Hz.
• Modulating control: 2...10 V; position signal: 2...10 V. Signal ranges are configurable.
• Motor running time: 2.5 s / 90°; adjustable running time: 2.5...10 s.
• Rotation angle: max. 95°, with adjustable mechanical stops on both sides; minimum permitted rotation angle: 30°.
• Direction of movement selected by 0/1 switch; manual adjustment using a push-button with locking option.
• Mechanical connection: universal clamp 8...26.7 mm; mechanical position indicator.
• Power and control connection: 1 m cable, 4x 0.75 mm².
• Power consumption during operation: 13 W; at rest: 2 W; sizing power: 23 VA.
• IEC/EN degree of protection: IP54; IEC/EN protection class: III, Safety Extra-Low Voltage (SELV).
