Siemens SQN72.2A4A20BC Servo Motor
230v
Electromotoric actuator for air dampers and control valves of oil or gas burners of small to medium capacity.
The SQN7... actuators are designed for driving gas or air dampers of oil or gas burners of small to medium capacity, for load-dependent control of the fuel and the combustion air volume:
• In connection with P-PI or PID controllers, such as the RWF40..., RWF5...
• Directly via the different types of burner controls, such as LOA..., LMO..., LME..., or LFL...
• In connection with 1- or 2-wire control or 3-position controllers
- Features
- Impact-proof and heat-resistant plastic housings
- Plug terminals for the electrical connections
- Maintenance-free gear train (can be disengaged)
- Internal position indication
- Easy-to-adjust end and auxiliary switches for setting the switching points
- Integrated electronic circuits
- Degree of protection IP54
• Holding torque: 0.7...1.3 Nm
• Running time: 4...30 s
• Direction of rotation: counterclockwise
