The Honeywell ML7420A8088E is a precision electric actuator designed for controlling valves in heating, ventilation, and air conditioning systems. It operates within ambient temperature limits of -10 to +50 °C at 5–95% relative humidity and can be stored between -40 and +70 °C under the same humidity range. The actuator supports medium temperatures up to 150 °C, or up to 220 °C when equipped with the optional high-temperature kit. It accepts a control signal input of 0–10 VDC or 2–10 VDC with an input resistance (Ri) of 100 kΩ and a maximum signal source resistance of 1 kΩ, ensuring precise modulation and reliable positioning control. Across North America, Europe, Asia, and worldwide, installation configurations and compatibility specifications may possibly vary according to regional HVAC system standards and control requirements.
