Honeywell MS4110A1002 2-Position S/R Direct Coupled Actuator 120V 88 lb-in

The Honeywell MS4110A1002 120V 2-Position Spring Return Actuator is a critical component used in HVAC systems, particularly air handling units and damper control applications. With an 88-pound-per-inch torque rating, this actuator is a two-position spring return device that runs on a 120-volt power source. It controls the flow of air or fluids in the system by detecting signals from the HVAC control system and using those signals to open or close dampers or valves in the ductwork. The actuator, which is installed in a variety of HVAC equipment, such as air handlers and damper systems, guarantees exact control over ventilation and airflow, improving system performance and efficiency. In the case of a power outage or other system fault, its spring return mechanism guarantees fail-safe operation by automatically returning the damper or valve to a predefined position, enhancing the safety and dependability of HVAC systems.
