VA9104-GGA-2S
The Johnson Controls VA9104-GGA-2S is a top-of-the-range electronic actuator that is tailored to offer a high degree of control in HVAC systems. This has an output signal that can be configured to either 0-10V or 4-20mA could be easily interfaced with many control systems and is powered by 24V. To achieve the best performance of the system, the included 500-ohm resistor serves to enhance the signal quality and as feedback. This actuator is reliable and does not have any ill effects on any sort of environment since it is made of stainless steel. Since it can be coupled with a damper or a valve to control airflow adequately, it is best suited for application in modulating dampers and valves since this will improve the quality of indoor air and energy.
