An exact-number listing identifies 0745648E 0745745Q as a “Circuit board, IR-module” and specifically describes it as a printed circuit board for an infrared module associated with OPTIMA. Separate records identify 0745648E as a printed circuit board/control module and provide the physical markings and approximately 730 g weight.
Product Introduction
The ABB 0745648E is a legacy ABB printed circuit board associated with the 0745745Q board designation and an IR-module assembly. Available records identify the hardware as a control/printed-circuit board rather than a conventional PLC I/O module or standalone power supply. The strongest available identification associates the board with an ABB OPTIMA infrared module, although detailed OEM documentation for the exact electrical implementation is not readily available in public sources.
The ABB 0745648E should therefore be treated as a system-specific PCB. Its actual operating role depends on the parent assembly, connected boards, field wiring, and the particular hardware revision. This is important when sourcing legacy ABB spare parts because a physically similar board may have different component population, connector assignments, or system dependencies.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
The 0745648E is most relevant to legacy ABB industrial automation equipment and OPTIMA-related installations where the original PCB must be replaced without redesigning the surrounding assembly. It may be encountered in maintenance programs involving older process-control or specialized industrial equipment.
The primary engineering concern is part identification rather than nominal electrical specification. Public listings are inconsistent: some describe 0745648E simply as a control PCB, while others incorrectly assign it functions such as digital input, communications, or generic power conversion. One exact-number record specifically links 0745648E with 0745745Q as an IR-module circuit board, which is the more useful identification for procurement.
Before approving a replacement, verify:
- Complete marking: Confirm 0745648E and check whether 0745745Q is also printed on the board.
- Date/revision codes: Compare markings such as 49/06 and 06/07 with the existing assembly.
- Parent equipment: Identify the ABB OPTIMA equipment or cabinet assembly in which the board is installed.
- Connector layout: Compare connector count, pin arrangement, PCB dimensions, and mounting points.
- Component population: Legacy boards can have revision-specific component changes even when the basic part number appears identical.
- Electrical characteristics: Do not assume 24VDC, 120VAC, 230VAC, RS-485, Ethernet, or analog I/O specifications from reseller descriptions.
- Commissioning: After replacement, verify the associated IR-module function and system diagnostics before returning the equipment to service.
Important Identification Warning
I would not classify ABB 0745648E as a generic power supply, digital input module, or communication module based on current public evidence. One source specifically identifies the 0745648E/0745745Q assembly as an IR-module circuit board, while other commercial listings provide generic or contradictory classifications.
For an engineering BOM, the safer description is:
ABB 0745648E — Printed Circuit Board / IR Module Control Board, associated with 0745745Q.

Procurement note: For this part, the most reliable replacement specification is 0745648E + 0745745Q + PCB revision/date code + parent ABB equipment model. Do not approve a substitute based solely on the description “ABB control board.”
