Siemens Building Technology GMA156.1P Actuator
The Siemens Building Technology GMA156.1P Actuator is a heavy-duty OpenAir GMA Series solution designed for critical airflow control. Engineered for modulating control, this spring return damper actuator delivers 62 lb-in (7 Nm) of torque, providing reliable operation for HVAC damper control in VAV systems, return air, and exhaust applications. Operating on 24V AC/DC, it features a 2 to 10 Vdc control signal with integrated position feedback and dual independently adjustable auxiliary switches for enhanced system monitoring and automation.
Built with a brushless DC motor, the GMA156.1P ensures a consistent 90-second runtime while offering a fail-safe spring return in under 15 seconds during power loss. The unit utilizes a self-centering shaft coupling to reduce installation time and prevent mechanical binding, making it a staple for contractors managing commercial HVAC maintenance. Its plenum-rated 3-foot cable and NEMA 1 (IP54) die-cast aluminum housing provide the durability required for demanding mechanical room environments.
Key Benefits- Precise Airflow Regulation: 2-10 Vdc modulating signal and signal inversion capability ensure exact positioning for energy-efficient ventilation.
- Fail-Safe Reliability: Mechanical spring return provides a positive seal on power failure, protecting critical system components.
- Simplified Installation: The self-centering shaft coupling fits 1/4" to 3/4" round or 1/4" to 1/2" square shafts without extra hardware.
- Diagnostic Feedback: Built-in feedback and dual auxiliary switches allow for remote monitoring of damper status.
Is the Siemens GMA156.1P suitable for outdoor use?
The unit features an IP54-rated aluminum enclosure; however, for direct outdoor exposure, an additional weathershield is recommended to protect the internal electronics from extreme elements.
What is the difference between the GMA156.1P and GMA156.1U?
The "P" designation indicates a 3-foot plenum-rated cable, whereas the "U" model typically features an appliance cable suitable for conduit connections.
Can I manually override the actuator position during commissioning?
Yes, this model includes a manual override crank, allowing technicians to position the damper and lock it in place for testing or during power outages.
