Information About GCA151.1U
The GCA151.1U is a Siemens damper actuator built for control damper applications requiring automatic spring-return operation. Its die-cast aluminum alloy housing provides NEMA 2 protection and an IP54 degree of protection for installation in compatible HVAC environments. A self-centering shaft coupling supports direct connection to damper shafts, while bidirectional CW/CCW rotation and 90° angular travel provide flexible installation. The actuator integrates with building automation systems using proportional control and position feedback for accurate damper positioning.
Key Features:
- 160 in-lb Torque: Provides rated torque for positioning compatible HVAC control dampers.
- Spring Return Operation: Automatically returns the connected damper to its fail-safe position when power is removed.
- Proportional Control: Supports modulating damper positioning through a 0–10 VDC control signal.
- Position Feedback: Provides actuator position feedback for integration with building automation systems.
- 24 VAC/DC Power: Operates from compatible 24 VAC or DC control power supplies.
- Self-Centering Coupling: Supports direct mounting to compatible damper shafts for secure positioning.
- 90° Rotation: Supports clockwise or counterclockwise operation across a 90-degree angular range.
- IP54 Protection: Die-cast aluminum housing provides protection against dust and splashing water.
The GCA151.1U delivers the reliability and precision required for proportional HVAC damper positioning and building automation control.
