The GM24S.2A actuator belongs to Belimo’s range of large damper actuators for shafts with diameters from 12 to 26.7 mm. The actuator is controlled by an open/close signal and is equipped with a universal clamp for direct tool-free mounting on the damper shaft. The package includes an anti-rotation mechanism. The actuator uses the Belimo M600 microprocessor in combination with the INFORM method to ensure full breakaway torque from standstill with high precision (sensorless INFORM-Drive system).

The actuator’s operating angle can be electronically limited on both sides via the Belimo Assistant 2 application. Both integrated auxiliary switches (latching relays) are adjustable and are used to indicate the damper end positions. The actuator is overload-protected, does not require end switches, and automatically stops at the end stop position.

Features

• Powerful 40 Nm actuator – suitable for large cross-section dampers in demanding HVAC and air-conditioning applications.
• Fast running time of 35 s – significantly shorter than standard actuators (150 s), adjustable within the range of 35 to 150 s.
• Two integrated auxiliary switches – adjustable switching points for damper position indication without external accessories.
• Detachable connection cable – easy installation and replacement without the need to disconnect the conductors.
• Configuration via Belimo Assistant 2 – wirelessly using NFC or by cable; setting the direction of rotation, operating angle, switching points and running time.
• Innovative INFORM actuator – the M600 microprocessor with INFORM-Drive technology ensures full torque from standstill and precise positioning.
• Side lever with locking function – enables manual adjustment and locking during installation, commissioning and maintenance.
• Overload protection – the actuator does not require end switches and automatically stops at the end stop.
• IP54 / Class III (PELV) – suitable for installation in areas with increased humidity and dust.
• Halogen-free FRNC cables – meet safety requirements for buildings and public spaces.
