Siemens Building Technology GIB136.1U Actuator

The Siemens GIB136.1U is a heavy-duty, non-spring return actuator designed for the precise management of return air, mixed air, and exhaust dampers in commercial HVAC systems. Delivering a high torque capacity of 310 lb-in (35 Nm), this direct-coupled unit is the industry-standard direct replacement for M9132-AGC-2, ensuring a seamless retrofit without extensive linkage adjustments. It operates on 24V AC/DC and utilizes three-position floating control, making it ideal for constant or variable air volume (VAV) installations that require stable, reliable damper positioning.

Engineered with a rugged all-metal housing and brushless motor technology, the GIB136.1U provides exceptional durability in demanding environments. It includes dual independently adjustable auxiliary switches for flexible interlocking and position signaling. The self-centering shaft coupling accommodates various shaft diameters up to 1 inch, simplifying Field installation. With a fast 125-second runtime (at 60Hz) and a manual override button, technicians can easily perform commissioning and system balancing. This actuator is UL873 and cUL listed, meeting strict safety and performance standards for building automation.

• High Torque Performance: Delivers 310 lb-in of force to handle large damper areas and high-pressure drops.
• Universal Compatibility: Serves as a drop-in replacement for Johnson Controls M9132-AGC-2.
• Field-Adjustable Switches: Contains dual auxiliary switches that can be set for specific angular positions.
• Ease of Installation: Features a self-centering coupling and 3-foot pre-cabled 18 AWG leads for faster wiring.
• Internal Protection: Integrated motor stall protection prevents damage during obstructions.

Is this a spring-return actuator?
No, the GIB136.1U is a non-spring return (NSR) model. It maintains its last position upon loss of power.

Will this fit onto my existing damper shaft?
Yes, the self-centering shaft adapter is designed for round shafts from 3/8" to 1" or square shafts from 1/4" to 3/4".

Can I use this for modulating 0-10V signals?
This specific model is designed for floating and on/off control. For 0-10V modulating requirements, refer to the GIB161 series.
