Siemens Building Technology GDE161.1P Actuator

The Siemens Building Technology GDE161.1P Actuator is a professional-grade modulating damper actuator engineered for precise control in high-performance HVAC systems. Built for 24V NSR 0/10VDC operation, this OpenAir series unit delivers 44 lb-in torque to drive dampers in constant or variable air volume (VAV) installations. As a direct-coupled solution, it features a 90-second runtime at 60Hz and utilizes synchronous motor technology to ensure consistent positioning without the drift common in lower-tier components. The non-spring return design is optimized for applications where the damper must maintain its last position during a power loss, while the built-in position feedback provides real-time verification to the building automation system.

Installation is streamlined for field technicians with a 3 ft plenum-rated cable and a universal shaft guide compatible with 3/8-inch to 5/8-inch diameters. The NEMA 2 rated housing and IP54 protection make it suitable for a wide range of mechanical room environments. With a low power consumption of only 3.3 VA when modulating, the GDE161.1P is a high-efficiency choice for direct coupled actuator replacements or new construction HVAC damper control projects.

• Precise Modulating Control: Supports 0-10 VDC or 2-10 VDC input signals with a self-adapting capability for simplified commissioning.
• Rugged Reliability: Maintenance-free design with a 100,000 full-stroke cycle rating and silicone-free gear lubrication.
• Technician-Friendly Features: Includes a manual override button, a mechanical range adjustment, and an easily visible position indicator.
• Quiet Operation: Runs at a noise level below 35 dBA, ideal for noise-sensitive commercial environments.

Is the GDE161.1P compatible with floating control?
Yes, while optimized for 0-10VDC modulating signals, this OpenAir series model can be configured for floating control in specific HVAC applications.

Can I manually adjust the damper position if power is cut?
The unit features a manual override tab that allows you to disengage the gear train and manually position the damper as needed during setup or service.

What size damper shaft does this unit support?
The factory-installed guide is designed for 1/2-inch shafts but can be adjusted or removed to accommodate 3/8-inch or 5/8-inch round and square shafts.
