Description
Product Overview
The ABB MPRC 086444-005 is a direct fiber optic module identified by ABB as PWA,MPRC,W/DIRECT FIBER and PWA,MPRC,W/DIRECT FBR OPT. It is associated with the MPRC family and is intended for use as a specialized communication/process-control board in compatible ABB systems.
The exact part number is important when maintaining an installed system. The direct-fiber configuration distinguishes this version from other MPRC boards, so replacement should be based on the complete part number, revision, and existing system configuration.
The supplied eBay listing identifies the unit as an ABB Direct Fiber Optic Module, MPN MPRC 086444-005, Revision C/C, with ECN 42602. The listed condition is New – Open box and the listed weight is approximately 950 g.

Product Summary
ABB MPRC 086444-005 is a specialized MPRC board with a direct fiber-optic configuration. ABB’s product record identifies Product ID 086444-005 and the description “PWA,MPRC,W/DIRECT FIBER.”
The board is particularly relevant to maintenance and replacement work on legacy ABB control equipment where the existing installation uses the direct-fiber version.
Because publicly available listings use several descriptions for this part, including Direct Fiber Optic Module, Measurement Process Board, and PLC card, the safest identification is the ABB product designation together with the exact MPN 086444-005 and revision C/C.

ABB’s current product data identifies 086444-005 as a spare-part item and gives the direct-fiber product description. Third-party product records provide the additional MPRC40 and ECN identifiers shown above.
Direct Fiber Optic Configuration
The key feature of this version is the direct fiber-optic configuration.
Fiber-optic communication can provide electrical isolation between connected equipment and avoids many of the grounding and electromagnetic-interference issues associated with long copper communication runs.
For an installed ABB system, however, the actual optical interface arrangement should be verified against the equipment documentation and the physical board before commissioning. Publicly available ABB product data for 086444-005 does not provide enough detail to safely specify the fiber wavelength, connector type, transmission distance, or optical budget.
For that reason, these values should not be assumed from the part number alone.
Identification Information
Several identification numbers can appear in documentation or on the physical board:
- MPRC 086444-005
- 086444-005
- Rev C/C
- ECN 42602
- MPRC40-86M44-05-010
- 44-05-010
- 43626
- EA=0000230711De
- EA=0000230711Df
Keeping these identifiers together is useful when sourcing a replacement, especially for older ABB equipment.
Application
The module is intended for compatible ABB industrial control and process-control equipment using the corresponding MPRC direct-fiber configuration.
Potential applications include:
- Industrial process control
- Legacy ABB automation systems
- Fiber-optic control-system communication
- Process measurement/control equipment
- System expansion or retrofit work
- Maintenance and spare-parts replacement
- Long-term critical spare inventory
The exact application depends on the host ABB system and its hardware configuration.
Installation Considerations
Before installing the board, disconnect the associated equipment according to the applicable ABB maintenance procedure.
Check the existing board location, connectors, fiber connections, and board identification before removing the original module.
Recommended procedure:
- Isolate the equipment from power as required.
- Record the existing board position and cable connections.
- Verify the replacement part number and revision.
- Inspect the PCB and connectors for physical damage.
- Use appropriate ESD protection when handling the board.
- Install the module in the correct position.
- Reconnect the fiber-optic interface carefully.
- Check that connectors are fully seated.
- Restore power according to the system procedure.
- Verify communication and system diagnostics.
- Confirm normal operation before returning the equipment to service.
Fiber-optic connectors should be kept clean and protected from dust. Do not touch exposed optical surfaces unnecessarily.
Replacement Compatibility
For a direct replacement, the preferred reference is:
MPRC 086444-005 — Rev C/C — ECN 42602
Do not treat another MPRC board as automatically interchangeable simply because it carries a similar MPRC designation.
Before substitution, compare:
- ABB Product ID
- MPRC model
- Revision
- ECN
- Fiber-optic configuration
- Connector arrangement
- Host-system compatibility
- Existing application configuration
Some online listings use 086444-505 as an alternate model reference, but this should be verified against the actual ABB system documentation before treating it as a direct substitute.
Inspection and Testing
For industrial automation spare parts, a practical incoming inspection should include:
Visual Inspection
Check the PCB, connectors, fiber interface, mounting points, labels, and components for signs of damage, corrosion, contamination, or overheating.
Part Number Verification
Confirm:
- MPRC 086444-005
- Rev C/C
- ECN 42602
Electrical Inspection
Check for obvious shorts, damaged components, broken solder joints, or connector damage before installation.
Functional Test
Where the appropriate ABB test environment is available, verify board startup, communication, and system diagnostics using the compatible host equipment.
Do not connect the board to an unknown system simply to perform a functional test. Incorrect configuration or incompatible hardware can cause additional equipment faults.
Storage and Handling
Store the module in an ESD-safe protective bag and keep it in a clean, dry environment.
Avoid:
- Excessive humidity
- Static discharge
- Mechanical impact
- Contamination of fiber connectors
- Unprotected storage of the PCB
- Repeated insertion and removal without proper handling
For long-term spare storage, retain the original identification labels and revision information with the module.
