GE Fanuc 44A391704-G01 I2C7B4 TUM2B

Product Overview

The GE Fanuc 44A391704-G01 I2C7B4 is an industrial TUM2B PC board designed for integration into compatible GE control equipment. Product references identify 44A391704-G01 as a TUM2B board used in the GE 7500 product family.

As a board-level automation component, it is intended to work as part of a larger control assembly. Its compact electronic architecture makes it suitable for equipment maintenance, system refurbishment, and replacement of an existing board with the same identification.

Technical Information

Publicly available sources do not provide a complete verified specification sheet for every electrical and environmental parameter. Therefore, the original equipment documentation should be used to confirm system-specific requirements.

Main Features

• Designed as a dedicated industrial control PCB.
• Associated with the GE TUM2B board designation.
• Suitable for compatible GE 7500-series equipment.
• Compact board-level construction supports cabinet integration.
• Useful for replacement, repair, and planned maintenance.
• Suitable for maintaining established industrial control infrastructure.

Board Structure

The 44A391704-G01 is built as a printed circuit board assembly containing electronic components, conductive traces, connectors, and related circuitry. These elements are arranged to perform the board’s designated control function within the host equipment.

The I2C7B4 identification can also be useful during equipment inspection. When replacing a board, technicians should compare both the main part number and the board markings before installation.

Industrial Applications

This GE Fanuc board is intended for compatible industrial automation and control equipment. It can be considered for applications involving production machinery, process-control equipment, industrial drive systems, and other installations using the corresponding GE control architecture.

For maintenance departments, keeping a matching spare PCB can simplify replacement work and help reduce equipment downtime.

Installation & Maintenance

Disconnect the host equipment from its power source before removing or installing the board. In addition, use appropriate ESD protection when handling the PCB.

Before installation, inspect the connectors, mounting points, and surrounding wiring. Verify that the replacement part number and board identification match the original assembly. After installation, follow the host system’s commissioning procedure and verify normal operation.
