Siemens Building Technology GBB161.1U NSR Damper Actuator 24VDC 0-10 VDC

The Siemens GBB161.1U is a non-spring return (NSR) damper actuator featuring high control performance in HVAC systems. At 24VAC, this actuator control signal of 0 to 10 VDC perfect for modulating type applications where high precision positioning is needed. The actuator runs on 50/60Hz frequency to match standard HVAC system frequency. Its non-spring return (NSR) design does not require a return spring, therefore it saves maintenance and operational complexity. In particular, the dampers in ventilation, heating and air conditioning systems as well as complex building automation systems.
