Siemens Building Technology GMA161.1P Actuator

The Siemens GMA161.1P is a high-performance OpenAir spring return actuator engineered for precise modulating control of dampers in technical HVACR environments. Designed to deliver 62 lb-in torque, this 24V AC/DC unit is the professional’s choice for 0 to 10 Vdc regulating applications. As the direct replacement for DCMS24-62-P, it provides a seamless transition for legacy systems, featuring a self-centering shaft coupling that minimizes installation time and ensures concentric alignment on damper shafts from 1/4" to 3/4". The 62 lb-in output provides sufficient force for medium-sized air dampers, utilizing brushless DC motor technology for stall protection and extended operational life. With a 90-second runtime and a rapid 15-second fail-safe spring return duration, this plenum-rated actuator meets stringent building codes while maintaining 0-10Vdc modulating accuracy for optimal air volume control.

• Universal Compatibility: Serves as a direct replacement for DCMS24-62-P, ensuring drop-in mechanical and electrical fit.
• Reliable Fail-Safe: Efficient spring return actuator mechanism ensures the damper moves to a predefined safety position during power loss.
• High Precision: Modulating 0-10Vdc control signal provides granular accuracy for VAV and air handling units.
• Durable Construction: Features a rugged NEMA 1 (IP54) die-cast aluminum housing suitable for demanding commercial mechanical rooms.
• Efficient Integration: Plenum-rated cable and pre-shipped 5° mounting preload streamline the commissioning process for contractors.

Common Questions

Is the GMA161.1P compatible with existing 24V systems?
Yes, it operates on a standard 24V AC/DC power supply and accepts the industry-standard 0-10Vdc modulating input signal, making it compatible with most Building Automation Systems (BAS).

How do I verify if this replaces my current actuator?
The GMA161.1P is specifically designated to replace the DCMS24-62-P. It handles dampers requiring up to 62 lb-in torque. Always verify your damper’s square footage and torque requirements before installation.

Can I manually override the spring during installation?
This model includes a manual override feature that allows technicians to lock the actuator in a specific position for testing or commissioning before power is applied.
