Description
The Johnson Controls M9203-GGB-2 is a functional and diverse electric proportional spring return actuator with an auxiliary switch that is used for controlling air dampers in HVAC systems. Another benefit is the incorporation of the spring-return mechanism that causes the damper to close in the event of power failure. This fail-safe design allows for correct airflow shutdown during an emergency. The M9203-GGB-2 also provides two (SPDT) auxiliary switches that enhances the performance of the relay. These switches provide electrical feedback of the position of the damper for interaction with Building Automation Systems for improved control and efficiency.
