Honeywell M6284D1000 Modutrol IV Actuator Motor
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Honeywell M6284D1000 is a heavy-duty Modutrol IV non-spring return actuator motor designed for floating or two-position control in commercial HVAC and industrial process systems. Functioning as a high-reliability electromechanical actuator, this unit drives air dampers, hydronic control valves, ventilation louvers, and combustion air control linkages. Constructed with a rugged zinc die-cast housing providing NEMA 3 / IP54 environmental protection, the M6284D1000 delivers 35 lb-in (4.0 Nm) of rated torque. Identifiable physical features include a dual-ended 0.375-inch square drive shaft for flexible mechanical linkages from either side of the motor, an external mechanical position pointer, and a standard 120 VAC 50/60 Hz power input drawing 15 VA.
Interfacing directly with Honeywell Series 62 floating controllers or standard 3-wire SPDT controllers, the M6284D1000 manages precise position control across adjustable angular travel ranges. Putting a replacement motor into service requires mechanical setup rather than digital programming. Internal cams inside the enclosure allow field setting of the stroke angle between 90 degrees and 160 degrees, operating at 30 seconds for a 90-degree stroke and 60 seconds for a full 160-degree rotation under nominal loads. Additionally, two integral factory-installed SPDT auxiliary switches must be adjusted to match required signal points or limit indications. ABC Industrial Parts can assist in sourcing fully tested replacement motors and hardware compatible with standard Modutrol IV mounting brackets and linkage kits.
Diagnostic assessment on the M6284D1000 is performed via direct physical indication. Operational position and travel state are verified by observing the external mechanical pointer against markings on the housing, while auxiliary switch trip points are adjusted using a screwdriver on internal cams. First-line operational checks include verifying 120 VAC supply voltage, inspecting 3-wire SPDT control circuit connections, confirming smooth linkage movement without binding, and checking stroke limits. Internal gear train or motor winding failures cannot be serviced in the field, making unit replacement or tested exchange through ABC Industrial Parts the standard route to restore system operation.

Communication and System Integration
The Honeywell M6284D1000 integrates into control loops using Honeywell Series 62 floating controllers or standard 3-wire SPDT line-voltage or low-voltage controllers. Operational power is supplied directly via a 120 VAC connection consuming 15 VA.
Auxiliary control circuits connect directly through two integral SPDT auxiliary switches inside the motor housing. These switches provide potential-free status feedback, limit interlocks, or sequence control for auxiliary equipment at field-set points along the shaft travel range.
Diagnostics and Status Indication
Position diagnosis for the M6284D1000 relies on an external visual indicator pointer located on the zinc die-cast housing. The pointer moves across calibrated markings on the case to show current shaft angle.
Auxiliary switch trip points are checked visually and mechanically by inspecting internal cam alignment. Adjustments to the auxiliary switch cams are completed manually using a screwdriver.
Replacement and Spare Part Considerations
When selecting a replacement for an M6284D1000 Modutrol IV motor, confirm that the system requires a 120 VAC 35 lb-in non-spring return actuator with floating or 3-wire SPDT control. Prior to putting the replacement into operation, set the internal cams to match the original unit's stroke angle between 90 and 160 degrees.
In addition to stroke length calibration, adjust the dual internal SPDT auxiliary switch cams to match the exact switching limits required by auxiliary circuits. The dual-ended 0.375-inch square drive shaft simplifies mounting alignment, connecting directly to standard Honeywell Modutrol IV mounting brackets and linkage assemblies.
