The Belimo GM230.2A actuator is an electric actuator for positioning dampers in building ventilation and air-conditioning systems. It provides a torque of 40 Nm, AC 100–240 V power supply, and supports Open/Close or 3-point control. The actuator is equipped with a detachable connecting cable and an NFC communication interface for wireless configuration using the Belimo Assistant 2 app.

Key features and benefits

• Visual status indication – a green LED indicates the actuator operating status.

• Easy installation – universal shaft clamp with anti-rotation strap, direct mounting on the damper shaft.
• Manual operation – a side lever allows manual adjustment even when de-energised (lockable position).
• Adjustable angle of rotation – electronic Min/Max end stops configurable via Belimo Assistant 2.
• High reliability – the actuator is overload-protected, does not require end switches, and stops automatically when the end stop is reached.
• Innovative drive unit – Belimo M600 technology with the INFORM method ensures full starting torque from zero speed with high precision (sensorless INFORM-Drive).
• Detachable cable – the connecting cable can be plugged into and unplugged directly from the actuator.
