GE 117D7790G1 IL2-B001

Introduction

Industrial control systems often depend on dedicated circuit boards for specific feedback and transfer functions. GE 117D7790G1 is identified as the IL2-B001 SPFB TC/MS/CVT PCB, with references linking it to GE EHC-2 electro-hydraulic control equipment.

Its specialized design makes it a useful replacement component for maintenance teams supporting legacy GE control installations.

Product Identification

• Brand: GE
• Model: 117D7790G1
• Board ID: IL2-B001
• Description: Stage Pressure Feedback Transfer Circuit
• Circuit Reference: SPFB TC/MS/CVT
• Equipment Family: GE EHC-2
• Component Category: Industrial PCB
• Primary Role: Feedback and signal-transfer circuitry

A GE parts reference also lists this board under the EHC-2 category, confirming its relationship with electro-hydraulic control equipment.

What It Does

The board forms part of the signal-processing path within an electro-hydraulic control system. Its documented function centers on stage pressure feedback and transfer, allowing relevant control signals to be handled within the wider system architecture.

Since the board performs a dedicated function, correct identification is important. The IL2-B001 designation can be used alongside the full GE part number when checking inventory or replacement requirements.

Design & Integration

The 117D7790G1 is supplied in PCB form rather than as a standalone field instrument. Its construction incorporates electronic components, conductive traces, and connection interfaces arranged for integration with compatible GE equipment.

A related parts list identifies IL2-B001 as 117D7790G1 and associates the circuit with SPFB TC/MS/CVT functionality.

This system-level role means technicians should consider the surrounding hardware when diagnosing a fault. A problem in wiring, sensors, connectors, or related boards may also affect the feedback signal.

Where It Is Used

The component is suited to applications involving:

• GE EHC control systems
• Electro-hydraulic control equipment
• Industrial turbine control
• Power-generation machinery
• Legacy automation installations
• Control-system refurbishment

It is commonly relevant to spare-parts inventories where maintaining existing equipment is more practical than replacing an entire control system.

Replacement Guidance

Before installation, compare the replacement unit with the existing board. Check the part number, IL2-B001 designation, connector positions, board revision, and physical condition.

After installation, follow the original equipment commissioning procedure and verify feedback signals before returning the system to normal operation.

For storage, keep the PCB in suitable anti-static packaging and protect it from moisture, dust, impact, and excessive temperature changes.
