Siemens Rotary Air Damper Actuator, 18Nm Motor Torque, 24V AC/DC - BPZ:GCA126.1E

This rotary air damper actuator by Siemens is a high-torque actuator designed for industrial applications. With a motor torque of 18Nm and power consumption of 5W, this energy-efficient actuator is reliable for controlling dampers up to 3m². It features a spring return function for emergency situations and can be used in tandem-mounted setups for increased torque.

Features & Benefits

• The 2-position control feature allows for precise damper adjustment, enhancing the efficiency and accuracy of HVAC system operations

• With a torque of 18Nm, the actuator delivers robust performance, ensuring reliable operation even in demanding applications

• The spring return feature, with a return time of 90/15 seconds, enhances safety by automatically returning the damper to its default position during power loss, preventing system failures

• The inclusion of two auxiliary switches enables seamless integration with other control systems, improving overall system functionality and allowing for better monitoring and control

Applications

• Emergency zero position movement during power failures

• Tandem-mounted configurations for increased torque

• Suitable for use in ventilation sections requiring precise control

Can it control dampers larger than 3m²?

This damper actuator is specifically designed for dampers up to 3m² in size.

Will it return to the zero position in case of a power failure?

Yes, the spring return function moves the actuator to its mechanical zero position during power failures.

Is it suitable for use in tandem-mounted setups?

Yes, this actuator can be mounted in tandem configurations for increased torque.

Can the span be adjusted between 0 to 90°?

Yes, the actuator features a mechanically adjustable span between 0 to 90° for precise control.

Does it come pre-wired with connection cables?

Yes, the actuator comes pre-wired with 0.9m long connection cables for easy installation.
