GE 117D6686G ILI-B002

The GE 117D6686G ILI-B002 is a specialized industrial printed circuit board identified as an STM Pressure Limit / PLMS PCB Board Module. It belongs to GE’s family of application-specific control boards and is intended for use in compatible industrial control equipment. Available product references identify 117D6686G with the ILI-B002 designation.

Product Overview

Pressure monitoring and pressure-limit functions are important in many industrial control applications. A dedicated pressure-limit circuit board can form part of the control architecture responsible for processing related signals and supporting protective or supervisory functions.

The GE ILI-B002 is therefore best treated as a specialized replacement PCB rather than a general-purpose automation module. For maintenance teams, accurate part-number identification is essential because boards with similar physical designs may perform completely different functions.

Key Identification

The available product information can be summarized as follows:

• Manufacturer: GE
• Part Number: 117D6686G
• Board Designation: ILI-B002
• Product Type: STM Pressure Limit / PLMS PCB
• Hardware Form: Printed circuit board module
• Primary Application: Pressure-limit and monitoring-related control functions
• Related Reference: 117D6690P3

Some product references list ILI-B002 117D6686G 117D6690P3 together, so the additional number should be checked against the markings on the original assembly before treating it as an interchangeable part.

Functional Role

The 117D6686G ILI-B002 is associated with pressure-limit circuitry within an industrial control arrangement. In a compatible system, this type of board can support the electronic processing required for pressure-related supervisory or limiting functions.

Its specialized role makes it particularly valuable when maintaining older GE equipment. Rather than replacing an entire control system, maintenance personnel may be able to restore operation by replacing the affected PCB.

Main Advantages

Application-specific design
The board is designed for a defined pressure-limit/PLMS function.

Easy identification
Both the 117D6686G part number and ILI-B002 designation can be used during procurement.

Legacy equipment support
It can be useful for plants that continue to operate established GE control systems.

Maintenance efficiency
Replacing an individual PCB may reduce the need for extensive system modification.

Typical Applications

The GE 117D6686G may be considered for:

• Industrial pressure monitoring systems
• Pressure-limit control equipment
• Process control installations
• Turbine and plant auxiliary systems
• Legacy GE industrial equipment
• Control-system refurbishment
• Industrial PCB replacement projects

Replacement and Installation

Before ordering a replacement, confirm the complete 117D6686G ILI-B002 identification. Also compare any additional board or assembly numbers, including 117D6690P3, where applicable.

Before removal, isolate the equipment according to site safety procedures. Record connector locations and wiring arrangements, then use suitable ESD precautions while handling the PCB.

After installation, inspect all connections carefully. The associated pressure-limit and monitoring functions should then be tested according to the equipment’s approved commissioning or maintenance procedure.

Industrial Supply Support

Specialized GE boards can be difficult to source when older control systems remain operational. Keeping the correct replacement PCB in inventory can therefore help reduce maintenance delays.

Our company supplies GE industrial automation spare parts, circuit boards, and control-system components for repair and replacement projects. When requesting a quotation, provide the complete 117D6686G ILI-B002 identification for accurate matching.
