GE 117D7790G1 IL2-B001

Product Overview

The GE 117D7790G1 IL2-B001 is a printed circuit board used in GE electro-hydraulic control equipment. Available parts references identify it as an SPFB TC/MS/CVT board, with the board designation IL2-B001. It is also listed within GE EHC-2 equipment and is associated with stage-pressure feedback and transfer circuitry.

As a specialized control board, the 117D7790G1 is intended to process and transfer electrical signals within the associated control architecture. Therefore, it is particularly relevant to maintenance and replacement work on legacy GE industrial control systems.

Product Information

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

The part number is documented as a GE circuit board associated with EHC-2 equipment. Independent parts listings also identify IL2-B001 with the 117D7790G1 board number and describe its circuit function as SPFB TC/MS/CVT.

Functional Characteristics

The board is designed for a specialized position within the control system rather than general-purpose PLC I/O. Its circuitry supports signal handling associated with pressure feedback and control transfer functions.

Because the board forms part of a larger electro-hydraulic control architecture, its performance depends on the surrounding control hardware, wiring, sensors, and associated signal-processing circuits. Consequently, correct part-number matching is especially

important when replacing a failed board.

Board Construction

The 117D7790G1 is supplied as a circuit-board assembly. Its design incorporates electronic components, signal-conditioning circuitry, connectors, and a printed wiring structure intended to interface with the corresponding GE control equipment.

The IL2-B001 designation provides an additional identification reference for technicians. In maintenance inventories, the board may therefore be identified by either 117D7790G1 or IL2-B001. This dual identification can make searching for replacement parts easier.

Applications

The GE 117D7790G1 can be considered for maintenance and replacement applications involving compatible GE EHC control systems. Typical environments may include industrial turbine control and other power-generation equipment where electro-hydraulic control technology is used.

Its specialized feedback and transfer circuitry makes it important for systems that depend on accurate signal processing within the control loop. A properly matched replacement can help restore the intended operation of the associated control equipment.

Installation and Maintenance

Before installing the 117D7790G1, technicians should verify the complete board number, IL2-B001 designation, system configuration, connector arrangement, and revision information. Because this is a specialized legacy PCB, visual similarity alone should not be used to determine compatibility.

During maintenance, inspect connectors and board surfaces for oxidation, contamination, physical damage, or signs of overheating. In addition, verify associated wiring and signal circuits before replacing the PCB.

Our company supplies the GE 117D7790G1 IL2-B001 for industrial automation and GE EHC maintenance requirements. Product condition, revision, and compatibility can be confirmed according to the customer's application before ordering.
