M9185A1018 Honeywell Datasheet
Overview
The Honeywell M9185A1018 Modutrol IV™ actuator is a high-performance, spring return motor designed for precise control of HVAC dampers and valves. Built for reliability in commercial and industrial environments, this actuator operates on a 24 VAC power supply and utilizes a proportional (135 ohm) control signal for accurate positioning.
Engineered as part of Honeywell’s trusted Modutrol IV series, the M9185A1018 delivers consistent torque output and dependable fail-safe operation. In the event of power loss, the integral spring return mechanism automatically drives the actuator to its normal position, protecting critical HVAC systems and maintaining safe operation.
