Honeywell M7284A1004 Modutrol Actuator

1.General Description

The Modutrol IV series actuators include more than 20 models, offering reliable product quality. They provide precise positioning control for dampers and valves in industrial furnaces, combustion chambers, and heaters. Key models include M7284A1004, M7284C, and M7284Q motor actuators.

People also know the Honeywell M7284A1004 as the M7284A1004 120V Valve/Damper. People sometimes call it the Honeywell M7284A1004, m7284a1004 honeywell, or Honeywell M7284A-1004 Modutrol Motor.

Other names include m7284a1004 honeywell actuator, Honeywell M7284A1004/U Electric Actuator, modutrol m7284a1004, m7284a1004 u, and m7284a1004 u honeywell. This motor lacks a spring return and controls dampers and valves. It serves precise control tasks. It works as a 120V Non-Spring Return Foot Mounted Actuator and a Modutrol IV Proportional Reversing Actuator.

l Built-in transformer provides 120V, 220V, or 240V power supply.

l Control types include: two-position, two-position floating, and proportional position (mA, V, 135 Ω). Spring-return and non-spring-return options exist. An optional feedback potentiometer is available, along with two auxiliary switches.

l Output drive: dual-shaft or single-shaft.

l Torque: spring-return 2.3/5.7 Nm, non-spring-return 4/8.5/17/34 Nm (150 lb-in ≈ 17 Nm for the M7284A1004).

l Stroke: 90°, 160°, adjustable 90°–160°.

l Ambient temperature: –28 °C to 65 °C.

l Optional explosion-proof housing available.

6.Application

The Honeywell M7284A1004 Modutrol IV actuator is a motor without a spring return. It controls dampers and valves in HVAC, boiler, and burner systems.

People also know the Modutrol IV Motor as the Modutrol IV Proportional Reversing Actuator. A 120V Non-Spring Return Foot Mounted Actuator is present. This device receives a modulating control signal of 4–20 mA or 2–10 V. It can accurately position dampers or valves between fully open and fully closed.

Perfect for heating, ventilation, and air-conditioning systems in commercial and industrial settings. It also works well for combustion air dampers, mixing valves, and fan control applications. The M7284A1004 offers precise control and stable performance.

Energy efficient, it can replace older Modutrol II and III motors. No one needs to make mechanical changes, which makes it great for retrofits or new installations. Reliable and provides high-torque, non-spring-return operation.
