Description
The Siemens GCA163.1P is a spring return, modulating damper actuator engineered for precise airflow control in commercial HVAC and building automation systems. Powered by a 24 VAC supply and accepting a 0–10 VDC modulating control signal, this actuator delivers proportional positioning accuracy across a wide range of air handling and ventilation applications. The start/span (ST/SP) adjustment feature allows field technicians to fine-tune the actuator’s operating range to match the specific requirements of the damper and system, reducing commissioning time and improving overall system performance.
Designed as part of Siemens Building Technologies’ trusted actuator lineup, the GCA163.1P integrates seamlessly with building automation systems (BAS) and direct digital control (DDC) platforms. The spring return mechanism ensures the damper returns to a fail-safe position upon loss of power, providing an added layer of safety and system protection.
