The Allen-Bradley MOX720-P4668E (80026-518-01) is a specialized DC/DC switching power supply designed for demanding industrial automation and process control environments. This unit, manufactured by Absopulse Electronics for Allen-Bradley, provides multi-rail power conversion, consolidating multiple voltage requirements into a single, compact module to reduce cabinet space and simplify system architecture.

Features

• Input Voltage: 56 VDC nominal (operational range 42 VDC to 58 VDC).
• Output Configuration: Seven isolated outputs across three regulated rails (5 VDC, 15 VDC, and 24 VDC).
• Output Capacity: 5 VDC at 5 A, 15 VDC at 2 A, and 24 VDC at 1 A.
• Industrial Design: Ruggedized construction suitable for high-temperature and high-vibration environments.
• Revision E: Represents an updated assembly revision of the MOX720 series, offering improved thermal performance and component reliability.

Applications

• Industrial control system logic and processor power.
• Analog instrumentation and gate-driver circuit supply.
• Field I/O, relay coil, and indicator lamp excitation.
• Automated coil handling and transport crane control systems.
• Industrial gas compressor and blending facility sequence control.

Technical Specifications

Installation Guidelines

• Ensure the power supply is installed in a well-ventilated enclosure to maintain thermal performance within the specified operating temperature range.
• Verify that the input DC source is stable and within the 42-58 VDC range before connection.
• Use appropriate wire gauges for the output channels to minimize voltage drop, especially on the 5 VDC logic rail.
• Always disconnect power from the system before inserting or removing the module to prevent electrical arcing or damage to the connector pins.
• Ensure the module is securely mounted to the chassis to withstand vibration in heavy-duty industrial environments.

FAQ

What is the difference between the MOX720-P4668E and the -D variant?

The suffix indicates a revision level. The -E variant is a newer revision of the internal circuitry and assembly. It is recommended to match the exact suffix of your existing unit to ensure compatibility with your specific wiring and pinout configuration.

What is the primary purpose of this power supply?

This module is designed to convert a 56 VDC input into multiple isolated, regulated DC voltages required by sensitive control boards, analog instrumentation, and field devices within an industrial automation rack.
