Siemens Building Technology GIB131.1U Actuator

Upgrade your air handling systems with the Siemens GIB131.1U Actuator, a robust non-spring return rotary actuator designed for the precise control of HVAC dampers. This direct replacement for M9124-AGD-2 and M9124-AGE-2 provides a high-torque solution of 310 lb-in, ensuring reliable 90-degree rotation for heavy-duty dampers in large-scale commercial applications. Operating on 24 VAC, this floating control actuator features a 125-second run time at 60 Hz, delivering steady positioning without the erratic hunting seen in lower-quality units.

The Siemens OpenAir GIB Series is engineered with a self-centering shaft coupling to reduce installation time and prevent mechanical binding. Its die-cast aluminum housing is NEMA 2 rated (IP54), offering superior protection against environmental factors on the job site. Specifically optimized for Siemens GIB131.1U specifications, this motor includes a manual override button, allowing technicians to verify stroke movements and damper alignment before final commissioning.

• High Torque Capacity: Delivers 310 lb-in (35 Nm) to drive large return, mixed air, or exhaust dampers.
• Drop-In Replacement: Seamlessly replaces Johnson Controls M9124-AGD-2 and M9124-AGE-2 with matching 125-second timing.
• Precision Floating Control: Reliable 3-point floating signal integration for accurate air volume management.
• Durable Construction: Features an all-metal, NEMA 2 enclosure suited for demanding HVAC environments.
• Fast Installation: Pre-cabled with 3-foot 18 AWG wiring and a self-centering shaft adapter.

Common Questions

What is the typical Siemens GIB131.1U wiring for floating control?
Standard wiring utilizes three conductors: a 24V common (Wire 1), a clockwise signal (Wire 6), and a counter-clockwise signal (Wire 7).

Can the GIB131.1U handle vertical damper shafts?
Yes, the actuator is designed for universal mounting; however, ensure the shaft diameter is between 3/8" to 1" for proper coupling.

Is there a manual override for troubleshooting?
A physical override button on the housing allows you to disengage the gear train and manually position the damper during setup.
