Siemens Building Technology GCA161.1P Actuator

Siemens Building Technology GCA161.1P Actuator

The Siemens GCA161.1P is a high-performance OpenAir spring return actuator engineered for precise modulating control of HVAC dampers in commercial air handling systems. This direct-coupled unit delivers a robust 160 lb-in torque, making it a reliable solution for return air, exhaust, and face-and-bypass dampers in both VAV and CAV installations. Operating on 24VAC/DC, it utilizes a 0-10VDC control signal to provide linear positioning with an integrated position feedback signal for closed-loop system monitoring. Built with a brushless DC motor and stall protection, the GCA161.1P ensures long-term reliability without the risk of burnout at end-of-stroke. The plenum-rated cable simplifies integration into ceiling spaces, while the patented self-centering shaft coupling accommodates various shaft sizes and reduces mechanical wear. In the event of power loss, the mechanical spring return fail-safe ensures the damper moves to its designated safety position in under 15 seconds, maintaining building pressure and safety protocols.

Key Benefits for the Field
  • High Torque Output: Provides 160 lb-in (18 Nm) to handle larger damper banks or high-static pressure applications without slipping.
  • Direct-Coupled Versatility: Features a self-centering shaft adapter that works with round shafts up to 1" or square shafts up to 3/4".
  • Reduced Setup Time: Ships with a 5° factory preload for immediate tight-seal compression and includes a manual override for commissioning before power-up.
  • Enhanced Durability: Housed in a rugged NEMA 2 die-cast aluminum enclosure designed for the demands of mechanical rooms.
  • Operational Feedback: The 0-10VDC feedback signal allows the building automation system (BAS) to verify actual damper position, reducing troubleshooting time.
Common Questions from the Shop

Can I use this for 4-20mA control signals?
Standard Siemens GCA161.1P units are optimized for 0-10VDC. For 4-20mA applications, you must install an external 500-ohm resistor or utilize a GCA15x series model designed for current-loop inputs.

How do I change the fail-safe direction (Clockwise vs. Counter-Clockwise)?
The fail-safe direction is determined by which side of the actuator faces the damper. Flip the actuator over to switch between CW and CCW spring return action.

Is this suitable for outdoor air intakes?
The unit is rated NEMA 2 (IP54). For true outdoor or rooftop applications where it is exposed to heavy rain or ice, it should be installed with an ASK75.1U weather shield to meet NEMA 3R requirements.
