The number 9.01.7-91.21.00-17 appears in online commercial listings for a MaK PCB/control-panel circuit board. A separate listing identifies the -11 variant as a motor-control plug-in card; that description must not automatically be applied to the -17 variant.
The MaK 9.01.7-91.21.00-17 PCB is a part-number candidate for a marine electronic control board associated with MaK equipment. Commercial spare-parts listings identify this reference as a PCB or circuit-control-panel component. However, the precise function of the photographed board, its equipment compatibility and its technical specifications require confirmation before a replacement is selected.
The supplied photograph shows a densely populated printed circuit board installed in a mounting frame. Its visible components include integrated circuits, electromechanical relays, resistors, capacitors, connectors and an ELBA-labeled DC-DC converter. These are common elements of electronic control assemblies, but their presence alone does not establish the board's specific control logic or intended engine function.
In marine machinery, electronic control cards can form part of systems responsible for signal processing, electrical switching, interlocking, monitoring or control. The exact duties of this particular board must be established from its original part identification, circuit documentation and the equipment in which it operates.
For marine engineers, electrical officers, technical superintendents and purchasing teams, correct identification is essential when sourcing replacement PCB assemblies. A similar-looking board or a related part number may have different circuitry, revisions or operating characteristics.
SM MARINE SERVICE™ can assist with identification and sourcing inquiries for the suspected MaK PCB reference. Buyers should provide the complete part number, photographs of the original board and its labels, and the parent equipment details to support a compatibility assessment.

A commercial listing specifically uses the title “Mak 9.01.7-91.21.00-17 PCB Circuit Control Panel” and includes the compact number 9017-912100-17. Another supplier catalog contains several neighboring MaK board references, demonstrating why the final digits should be checked carefully.
Customers often search for a replacement using only the number printed on an electronic card. For that reason, the full part number should be included in the product page title, identification table, image ALT text and relevant body copy only after the number is confirmed against the actual unit.
Important: Do not label the photographed PCB as 9.01.7-91.21.00-17 solely because the candidate number is associated with a similar commercial listing. Verify the board marking or compare the original unit with an authoritative parts reference first.
The following features are visible in the photograph or describe the assembly at a general component level. They are not a substitute for a verified manufacturer datasheet.
Populated electronic printed circuit board.
Multiple integrated circuits for electronic processing or control functions.
Electromechanical relays for circuit switching.
ELBA-labeled DC-DC converter module.
Passive electronic components, including resistors and capacitors.
Terminal and plug connections for electrical integration.
Mounting frame and multi-pin terminal arrangement.
Potential use as a marine machinery electronic spare, subject to confirmed identification.
The specific control function, supported input/output signals, communication interfaces and engine-system compatibility remain unverified.
If the part number and MaK association are confirmed, the PCB may be relevant to maintenance and spare-parts sourcing for compatible MaK marine machinery.
Potential application categories for an electronic control card of this general type include:
Marine engine electrical and electronic control assemblies.
Engine-room automation and control panels.
Machinery monitoring or switching circuits.
Relay-based control and interlocking circuits.
Electronic control-panel maintenance and replacement.
These are general application categories, not confirmed functions of the photographed board. There is insufficient evidence to state that this specific PCB controls engine starting, a particular interlock, fuel injection, speed regulation or any named engine model.
Before ordering, verify the original board number, equipment model, circuit position and applicable documentation.

A DC-DC converter's presence does not establish the supply requirements of the complete PCB. Likewise, the voltage printed on an individual relay or capacitor cannot be used to infer the board's overall operating voltage.
Marine replacement work should use the original equipment documentation, confirmed part number and appropriate electrical checks. Do not apply power to an unidentified board based on visual similarity alone.
Illustrative component reference only; not a verified technical drawing of this MaK assembly.
The visible module is labeled ELBA DC-DC CONVERTER. DC-DC converters generally convert one DC voltage level to another. The input range, output voltage, isolation characteristics and ratings of this particular module must be confirmed from its complete label or documentation.
The board contains multiple integrated circuits. Their exact part numbers and individual functions are not sufficiently readable in the supplied photograph.
Several relays are visible. Relays typically switch electrical circuits in response to a control signal. Their exact duties in this assembly are unknown.
The board contains numerous passive components used in electronic circuits. Their precise circuit roles cannot be established from the photograph alone.
The assembly includes terminal connections along the lower edge and green screw-terminal blocks near the top. Their pin assignments and wiring arrangements must be obtained from the correct circuit diagram.
