Description
🔹 Product Overview
The GENERAL ELECTRIC 44A397860-G01 is a CYCL4C printed circuit board used in legacy GE FANUC industrial control equipment. Available parts references identify the board as CYCL4C and associate it with the GE Model 550 control platform.
The part number is also cross-referenced with GE FANUC 44B398265-001 in equipment parts listings. This makes the complete board number important when sourcing a replacement, especially where several revisions or related boards exist within the same control family.
This is a legacy industrial PCB rather than a standard PLC I/O module. For replacement work, the original cabinet documentation, board label, connector arrangement, and installed control-system model should be checked before installation.

Available references identify 44A397860-G01 specifically as a CYCL4C PC Board for Model 550 equipment. Detailed electrical ratings such as supply voltage, current consumption, I/O channel count, and operating temperature were not reliably established from the available documentation, so these values should not be estimated.
🔧 CYCL4C Board Function
The CYCL4C designation identifies the functional board type within the GE FANUC control architecture. Unlike a conventional PLC digital input or analog output card, this board is part of the equipment’s dedicated control electronics.
When replacing a board in an older machine or industrial controller, the important point is not simply whether the PCB physically fits. The correct board revision and associated control-system configuration should also match.
🏭 Typical Applications
The 44A397860-G01 may be encountered in:
- GE FANUC Model 550 control systems
- Legacy industrial machinery
- CNC and machine-control equipment
- Factory automation systems
- Industrial drive/control cabinets
- Maintenance and spare-parts inventories
- Equipment restoration and retrofit projects
Its strongest use case is normally replacement of an existing CYCL4C board with the same identification.
🛠️ Installation & Replacement Guide
1. Verify the original board
Check the installed PCB for:
- 44A397860-G01
- CYCL4C marking
- Revision information
- Connector layout
- Board identification labels
2. Power down the equipment
Follow the machine manufacturer’s shutdown and lockout procedure before removing the control board.
3. Document the original installation
Take photographs of connector positions and board orientation. This is especially useful when maintaining older GE FANUC equipment.
4. Inspect the replacement
Check the PCB, connectors, components, solder joints, and mounting points for physical damage or contamination.
5. Install carefully
Insert the board using the original card guides and mounting hardware. Do not force connectors or apply excessive pressure to the PCB.
6. Verify operation
After installation, inspect wiring and system diagnostics before returning the machine to normal production.
⚠️ Replacement note: Do not substitute another GE board simply because it has a similar physical format. The CYCL4C function and exact part number should be matched.
🔄 Compatibility & Cross-Reference
The 44A397860-G01 is listed as CYCL4C and is associated with the GE FANUC Model 550 platform. Parts references also connect this number with 44B398265-001 / CYCL4C.
This cross-reference can be useful when searching for legacy replacement stock, but it should still be verified against the actual board marking and machine documentation.
Before ordering, confirm:
- Complete part number
- CYCL4C designation
- Revision
- Connector configuration
- Original machine/control model
- Existing board identification
- Required software or configuration, if applicable
❓ Frequently Asked Questions
Q1: What is the GE 44A397860-G01?
It is a GE FANUC CYCL4C printed circuit board associated with Model 550 control equipment.
Q2: Is it a standard PLC I/O module?
No. Available references identify it as a dedicated CYCL4C PC board rather than a conventional PLC I/O module.
Q3: What is the board’s alternate reference?
Available GE parts listings associate 44A397860-G01 with 44B398265-001 / CYCL4C.
Q4: What equipment is it used with?
It is associated with GE FANUC Model 550 industrial control equipment.
Q5: Can another GE 44A-series board replace it?
Not automatically. The board function, revision, connectors, and control-system application must match.
Q6: Are the electrical specifications available?
Reliable model-specific voltage, current, and environmental ratings were not confirmed from the available documentation. These should be taken from the original equipment manual or engineering drawings.
