Description
Allen-Bradley 80190-440-03-R
Product Introduction
Inside an SMC Flex soft starter, the interface board sits between the controller electronics and the high-power switching architecture. The Allen-Bradley 80190-440-03-R is identified as an SMC Flex Interface PCB Board, and Rockwell’s own documentation lists it as an interface board installed at one per controller in its medium-voltage SMC Flex equipment.
This is not a general-purpose PLC communication card. It is a platform-specific internal PCB whose compatibility depends on the SMC Flex controller architecture, board revision, power section, and associated fiber-optic/control hardware. Rockwell documentation also lists separate fiber-optic boards and cables around this interface, so replacing the PCB should be handled as a system-level maintenance task rather than a generic board swap.

Rockwell’s medium-voltage SMC Flex documentation is the strongest source for the board’s system role: 80190-440-03-R is listed as the Interface Board, one per controller. The same spare-parts sections identify voltage-sensing boards and fiber-optic components around it.
Application Scenarios & Pain Points
1. SMC Flex solid-state motor starting
The 80190-440-03-R belongs to the SMC Flex soft-starter architecture used for controlled starting and stopping of industrial motors. It is an internal board, so its function is tied to the controller rather than to a standalone field signal network.
2. Medium-voltage SMC Flex controllers
Rockwell’s medium-voltage documentation specifically lists the 80190-440-03-R Interface Board as a common spare part for SMC Flex controllers. In the Series K or later medium-voltage documentation, one interface board is specified per controller.
3. High-power motor control maintenance
SMC Flex systems use semiconductor switching components and dedicated sensing/control boards. When an interface board fails, replacing only the visibly damaged PCB may not address an underlying fiber link, sensing-board, gate-driver, or power-section problem.
4. Legacy SMC Flex repair
This part is particularly relevant to maintenance teams supporting installed SMC Flex equipment. Because the part is reported as discontinued, the procurement process should focus on exact part-number and revision matching rather than assuming that any SMC Flex interface PCB is equivalent.

Engineer’s Guide — Field Pitfalls to Avoid
1. Do not classify it as a generic PLC interface module
The 80190-440-03-R is a dedicated SMC Flex interface PCB. It is not an Allen-Bradley ControlLogix or CompactLogix I/O module, and the common online descriptions calling it a generic communication board are misleading.
2. Do not confuse low-voltage and medium-voltage SMC Flex configurations
Rockwell documentation lists this board in medium-voltage SMC Flex spare-parts tables. The surrounding system hardware can change substantially with controller voltage and construction. Verify the exact SMC Flex controller model before approving a replacement.
3. Inspect the fiber-optic path before condemning the PCB
The SMC Flex architecture includes dedicated fiber-optic hardware. Rockwell lists both fiber-optic boards and cables alongside the 80190-440-03-R. A communication or power-stage fault can therefore originate outside the interface PCB.
4. Match the revision exactly
The “-R” suffix is part of the supplied part number. Do not automatically replace 80190-440-03-R with an older-looking 80190-440-03 board simply because the base number is similar. Obtain the installed board’s complete label and compare it with the replacement.
5. Do not apply unverified board-level voltage specifications
Several secondary websites claim that the board operates from 24 VDC or provide specific temperature, I/O, and communication specifications. I would not use those figures as engineering acceptance criteria without the applicable Rockwell SMC Flex manual or schematic. The board receives its operating power through the host controller architecture.
6. Check the surrounding spare parts
For medium-voltage SMC Flex equipment, Rockwell identifies the interface board alongside voltage-sensing boards, gate-driver boards, fiber-optic boards, and fiber-optic cables. If the original failure involved a power pole or SCR fault, inspect the associated components before installing the replacement PCB.
FAQ
What is Allen-Bradley 80190-440-03-R?
It is an SMC Flex Interface Board used inside Allen-Bradley/Rockwell SMC Flex solid-state soft-starter equipment. Rockwell’s medium-voltage SMC Flex manual lists it as an interface board, with one board per controller.
Is 80190-440-03-R a PLC module?
No. It is an internal SMC Flex PCB, not a standalone PLC CPU, I/O module, or fieldbus adapter.
What equipment uses 80190-440-03-R?
Rockwell documentation identifies it within medium-voltage SMC Flex motor-controller architectures, including Series K or later equipment and OneGear SMC Flex equipment.
Does the board connect directly to the SCR power devices?
It participates in the SMC Flex controller interface architecture, while separate fiber-optic components are used elsewhere in the system. Rockwell’s spare-parts tables list the 80190-440-03-R separately from the fiber-optic board, gate-driver boards, and fiber-optic cables.
Is 80190-440-03-R discontinued?
Secondary industrial-equipment records currently identify the part as discontinued by the manufacturer. Because the Rockwell documentation confirms the part’s historical system role but does not establish current commercial availability, verify actual availability and condition before planning a shutdown replacement.
Can 80190-439-03 replace 80190-440-03-R?
Some equipment records list 80190-439-03 as a related spare model, but that alone is not sufficient evidence of a universal direct replacement. Verify the host SMC Flex controller, hardware revision, firmware, connector arrangement, and Rockwell documentation before substituting it.
What should procurement verify?
For a critical SMC Flex replacement, record the complete board number, revision, host controller model, voltage class, serial/configuration information, connector condition, and associated fiber-optic hardware. If the replacement is used or refurbished, verify the actual board condition and test status rather than relying on a generic “new” or “original” listing.
