Honeywell M9484F1057 | Modutrol IV Actuator
Product Description
The Honeywell M9484F1057 is a Modutrol IV actuator designed for low-voltage, reversing proportional control of dampers, valves, and auxiliary equipment. It is widely used in oil and gas burner systems, HVAC applications, and industrial automation requiring precise modulating control.
This actuator operates with a 135-ohm proportional signal and provides an adjustable stroke from 90° to 160°, ensuring flexible positioning. The non-spring return design maintains the last position upon power loss. Built with rugged construction, screw terminal wiring, and UL/FM/CSA approvals, it suits harsh industrial environments and long-term reliability.
