Siemens GQD121.1A Spring Return Damper Actuator
Guarantees safe air flow management with automatic shutdown during power failures.
Siemens GQD121.1A Spring Return Damper Actuator is designed for safe air control in HVAC systems. In addition, its 2 Nm torque precisely positions medium-sized dampers. Moreover, the 24V AC/DC supply and On/Off control signal allow easy integration with standard automation panels.
The spring return mechanism closes the damper in 15 seconds upon power loss, enhancing safety. The motor drives the damper to 90° open in 30 seconds. Consequently, this fail-safe feature is critical for fire or emergency scenarios. Furthermore, two auxiliary contacts provide position feedback to central monitoring systems.
