Honeywell M9484F1057 Modutrol IV Proportional Motor

Overview

The Honeywell M9484F1057 is a proportional, non-spring return Modutrol IV motor. It controls burner firing rate valves, dampers, and auxiliary equipment in oil or gas burner systems. This actuator uses a 135-ohm proportional input signal for precise shaft positioning. Its stroke adjusts between 90° and 160°, and it includes two internal auxiliary switches for feedback and safety. The motor features a vibration-resistant electronic drive and a weather-resistant NEMA 3 enclosure.
