GE IL3-D001 117D7730G1

Product Overview

GE IL3-D001 117D7730G1 is a specialized LCU CV Amplifier PCB used in GE electro-hydraulic control equipment. Available parts references identify IL3-D001 as the board designation and 117D7730G1 as its corresponding GE part number.

The board is associated with the Load Control Unit (LCU) and provides dedicated amplifier circuitry for control-valve-related signals. Its specialized design makes it suitable for maintenance and replacement of established GE control systems.

Product Parameters

A GE parts listing also describes this assembly as a Load Control Unit Control Valve Amp Analog printed circuit card.

Main Features

• Dedicated LCU control-valve amplifier circuitry
• Industrial PCB construction
• Designed for integration into GE control equipment
• Suitable for legacy system maintenance
• Compact board-level architecture
• Useful for replacement and refurbishment projects
• Clearly identified by both board and part numbers

Structure and Function

The assembly is built around a rigid PCB with electronic components, signal-conditioning circuitry, and interface connections. Its amplifier circuitry is intended to process control-related signals within the LCU architecture.

The board does not normally operate as an independent controller. Instead, it works with associated control cards, wiring, power circuits, and valve-control hardware. Therefore, system-level compatibility should be checked before installation.

Application Areas

This component can be used in industrial electro-hydraulic control systems, turbine-related control equipment, power-generation installations, and other GE systems using dedicated load-control circuitry. Public parts references specifically place this family of boards within GE EHC-2 equipment.

Installation & Maintenance

Before replacing the board, verify the complete IL3-D001 / 117D7730G1 identification, connector arrangement, board revision, and associated equipment.

Remove system power before handling the PCB and follow applicable electrical safety procedures. ESD protection should be used during installation. Inspect connectors and surrounding wiring for corrosion, contamination, loose connections, or signs of overheating.
