Honeywell 50017460-001
The Honeywell 50017460-001 Internal Transformer is a multi-voltage transformer kit designed for compatible Honeywell Modutrol IV electric motors used in commercial and industrial control applications.
This internal motor transformer provides a 24 VAC secondary output from a selectable 24 VAC, 120 VAC, or 230 VAC primary supply. Its multi-tap configuration allows the transformer to be connected to the appropriate supply voltage while providing the electrical power required by compatible Modutrol IV motor control systems.
The Honeywell 50017460-001 belongs to the Modutrol IV motor accessory family and is intended primarily for internal installation in compatible Series 2 motors. Honeywell product literature also identifies applications involving compatible Series 3 motors.
One of the important functions of this transformer is electrical isolation. The 50017460-001 provides a 24 VAC isolated secondary supply, helping accommodate motor applications that require the correct separation between incoming power and the motor’s low-voltage control circuitry.
The transformer incorporates color-coded primary leads to simplify identification of the available input voltage connections. The brown primary lead corresponds to 24 VAC, the white lead to 120 VAC, and the blue lead to 230 VAC. A black conductor serves as the common primary connection.
Two brown secondary leads provide the 24 VAC output used to supply the corresponding motor terminals in the compatible installation.
The multi-voltage design allows the same transformer model to be used in several supported electrical supply configurations. This can be useful when replacing existing motors, maintaining industrial control equipment, or converting compatible motor installations to an approved power configuration.
The transformer is designed to mount inside the motor wiring compartment, eliminating the need for a separate external transformer enclosure in supported applications.
Its internal installation arrangement also helps maintain the intended equipment configuration when replacing or servicing compatible Honeywell Modutrol IV motors.
The installation kit includes the transformer and mounting hardware. Honeywell installation instructions identify the appropriate placement of the transformer within the motor assembly and describe the electrical connections required for proper operation.
The 50017460-001 is particularly relevant for applications involving compatible replacement motors associated with the Honeywell M734 and M934 families.
Honeywell Modutrol IV motors are widely used in systems requiring controlled mechanical positioning. These applications can include industrial combustion air dampers, boiler control equipment, ventilation systems, HVAC automation, and motor-driven valve linkage assemblies.
Within these systems, the internal transformer provides an electrical power conversion function. It does not independently control motor position, provide burner flame supervision, or replace the motor’s control circuitry.
For equipment maintenance, selecting the proper transformer is essential to ensure compatibility with the available electrical supply and the specific motor configuration.
Before replacing an existing motor transformer, maintenance technicians should verify the motor series, input voltage, required secondary voltage, mounting arrangement, electrical terminal identification, and manufacturer installation instructions.
The Honeywell 50017460-001 must not be confused with the 50017460-003 transformer kit. Although both belong to the same accessory family, the 50017460-003 is intended for 120 VAC primary supply applications, while the 50017460-001 supports selectable 24 VAC, 120 VAC, and 230 VAC primary connections.
Installation should be completed by qualified personnel familiar with industrial electrical equipment. Electrical power must be disconnected before performing wiring or replacement operations, and all connections must comply with applicable electrical codes.
After installation, the motor assembly should be inspected and tested according to Honeywell procedures to confirm correct electrical operation.
