GE 117D7790G1

Product Overview

GE 117D7790G1 is an industrial printed circuit board used in GE Electro-Hydraulic Control (EHC-2) equipment. Available parts references identify it as the IL2-B001 board and describe its function as a stage pressure feedback and transfer circuit.

This specialized PCB is designed to handle control signals within an electro-hydraulic control architecture. It can be particularly useful for maintenance and replacement work on established GE industrial control systems.

Key Specifications

Item	Description
Manufacturer	GE
Part Number	117D7790G1
Board Designation	IL2-B001
Product Type	Industrial Control PCB
Circuit Function	Stage Pressure Feedback / Transfer
Circuit Reference	SPFB TC/MS/CVT
Associated System	GE EHC-2
Application	Electro-Hydraulic Control

The available parts documentation and supplier references consistently associate this board with GE EHC-2 equipment and the IL2-B001 designation.

Functional Features

The board provides dedicated circuitry for pressure-feedback and signal-transfer functions within the control system. It is not a general-purpose PLC I/O module, but a specialized board designed for a specific control architecture.

Key characteristics include:

• Dedicated industrial control circuitry
• Stage pressure feedback functionality
• Signal transfer within the EHC system
• PCB-based construction
• Suitable for legacy system maintenance
• Compatible with applications requiring the corresponding board configuration

Construction

The assembly uses a rigid printed circuit board populated with electronic components, signal-conditioning circuitry, and interface connections. The IL2-B001 designation provides an additional identification reference when searching for the correct spare part.

Because the board operates as part of a larger control system, its performance depends on associated wiring, sensors, interface circuits, and other control boards.

Application Areas

Typical applications include GE electro-hydraulic control systems, industrial turbine control equipment, power-generation installations, and related maintenance projects. The part is especially relevant when an existing EHC system requires replacement of a dedicated control PCB.

Installation & Maintenance

Before replacement, verify the complete part number, board designation, connector arrangement, revision, and host-system configuration. Disconnect power and follow the equipment's established safety procedures before removing the original PCB.

During maintenance, inspect connectors, wiring, and the surrounding cabinet for contamination, corrosion, loose connections, or overheating. Use appropriate ESD precautions when handling the board.
