Siemens Actuator Damper, Spring Return, 2 Position, 24 VAC/DC, Plenum Cable, 160 in-lb

Siemens GCA126.1P Electronic Damper Actuator Direct Coupled 2 position Spring Return Plenum Cable Dual Auxiliary Switches.
Designed for control of building HVAC dampers, the OpenAir Direct-coupled, Spring Return Electronic Actuators are two-position (on/off) control.
The OpenAir GCA Series Damper Actuators are ideal for constant or variable air volume installations for the control of return air, mixed air, exhaust, and face and bypass dampers that require up to 160 lb.-in. (18 Nm) torque. The actuators are designed for applications where the damper is required to return to a fail-safe position when there is a power failure.
Features:
• 24 Vac/dc compatible • Visible position indication • Self-centering shaft coupling • Bidirectional fail-safe spring return • Rugged all metal housing • Accepts shaft diameters up to 1" (25 mm) • Quiet, low-power operation • Brushless DC motor technology with stall protection • Assembled in the U.S.A. • Manual override • Precabled
