Siemens GCA166.1U

The Siemens GCA166.1U is a rotary damper actuator from the OpenAir GCA series, designed for reliable control in ventilation and HVAC applications. It features a spring return mechanism with a torque output of 160 lb-in (18 Nm), making it suitable for managing dampers that require precise positioning. This actuator operates on 24 VAC/DC power and accepts a 0 to 10 VDC control signal, allowing smooth modulation of damper movement. With a run time of 90 seconds, it provides efficient response while the built-in dual auxiliary switches offer additional control and feedback options. Distributed by BSP Automation, the GCA166.1U combines robust performance with versatile control to support effective airflow management.
