Product Description

The Siemens GMA131.1P is a fail-safe damper actuator with spring return, featuring a self-centering shaft coupling and a 90° stroke with CW/CCW rotation. It operates on 19.2 to 28.8V AC/DC input, has a 3.5W power rating, and provides a 0 to 10V DC output signal. This plenum-rated actuator is compatible with building automation systems and has a NEMA 1 / IP54 enclosure rating.

Frequently Asked Questions

What is the Siemens GMA131.1P damper actuator used for?

The Siemens GMA131.1P is a fail-safe damper actuator with spring return, used in HVAC building automation systems to control air dampers in plenum-rated spaces. It provides 62 in-lb torque, operates on 19.2 to 28.8V AC/DC, and features a 90° stroke with CW/CCW rotation for precise airflow regulation.

What are the specifications of the Siemens GMA131.1P actuator?

The Siemens GMA131.1P is a floating point, spring return actuator with 62 in-lb torque, 19.2 to 28.8V AC/DC input, 3.5W power rating, and 0 to 10V DC output. It has a self-centering shaft coupling, 90° stroke, NEMA 1 / IP54 enclosure, and is plenum rated for building automation compatibility.

Where to buy the Siemens GMA131.1P actuator worldwide?

3G Electric supplies the Siemens GMA131.1P actuator worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this fail-safe damper actuator to any country.

How to install the Siemens GMA131.1P spring return actuator?

Mount the Siemens GMA131.1P directly onto the damper shaft using its self-centering coupling, ensuring the shaft rotates freely. Connect hardwired power (19.2 to 28.8V AC/DC) and control signal (0 to 10V DC) per wiring diagram. Verify spring return direction (CW/CCW) before commissioning. Follow Siemens installation manual for torque and stroke settings.
