ABB XV C769 AE101 OEI Interface Board

Product Overview

ABB 3BHE006373R0101 XVC769 AE101 is an Optical Electrical Interface (OEI) Board used in ABB medium-voltage drive equipment. ABB’s own spare-parts documentation lists this part as an OEI board within the filter assembly of the ACS2000 medium-voltage drive.

The board provides an interface between optical communication paths and electrical control circuitry. It forms part of the drive’s internal signal and communication architecture, helping the system exchange control information between different functional sections.

Key Technical Data

ABB documentation specifically identifies this component as an Optical Electrical Interface (OEI) Board and shows one unit in the ACS2000 filter assembly.

Functional Characteristics

The board is designed for applications where reliable signal transmission is required inside a high-power drive system. Optical communication can provide electrical isolation between control and power-related sections, which is valuable in equipment exposed to switching noise and high electrical potentials.

Its main characteristics include:

• Optical-to-electrical interface functionality
• Integration with ABB medium-voltage drive architecture
• Industrial-grade circuit-board construction
• Compatibility with dedicated ABB drive assemblies
• Support for reliable internal signal communication
• Coated-board versions for improved environmental protection

Some secondary sources describe additional electrical ratings and interface details, but these specifications are not consistently supported across independent sources. For this reason, system documentation should take priority when verifying exact electrical limits.

Board Construction

The assembly is based on a printed circuit board populated with electronic interface circuitry and connection points. Depending on the specific production version, protective coating can be applied to the board surface.

A coated construction can provide additional resistance against moisture, dust, and other environmental contaminants. This feature can be useful in industrial installations where electronic equipment operates inside demanding electrical cabinets.

The board is not normally treated as a standalone controller. Instead, it works as one functional element within the complete drive architecture. ABB documentation places it alongside components such as an IGBT power-supply board, synchronization board, high-voltage relay, and high-voltage divider board.

Typical Applications

This interface board is particularly relevant to ABB medium-voltage drive systems. ABB's spare-parts documentation confirms its presence in the ACS2000 drive filter assembly.

Typical industrial environments may include:

• Mining and mineral processing
• Cement production
• Metals and steel plants
• Oil and gas facilities
• Water treatment
• Large industrial pumping systems
• Manufacturing plants
• Power and utility installations

It is especially valuable when maintaining an existing drive installation where the original hardware configuration needs to remain unchanged.

Installation and Maintenance

Before replacing the board, technicians should completely isolate the associated drive and follow the applicable electrical safety procedures. Medium-voltage equipment can retain hazardous energy even after normal shutdown.

During replacement, check the board identification, connector arrangement, physical condition, and surrounding wiring. Also inspect nearby components for overheating, contamination, loose connections, or evidence of electrical stress.

Use appropriate ESD protection when handling the circuit board. Avoid touching conductive tracks and electronic components directly. If the board has a protective coating, avoid scratching or removing that coating during inspection.

After installation, verify the connections carefully before restoring power. Drive commissioning should follow the relevant ABB service documentation and the configuration requirements of the host system.

Spare Parts and Compatibility

For legacy ABB drive maintenance, accurate part identification is important. The same family of industrial boards can have different revisions or functions, so physical similarity alone should not be used to determine compatibility.

ABB's spare-parts documentation provides particularly useful confirmation because it identifies this component directly within an ACS2000 filter assembly.

For procurement, it is advisable to provide the complete part number and board designation when requesting a replacement. Our industrial automation supply service supports sourcing of ABB drive boards and other hard-to-find automation components, including discontinued and legacy spare parts.
