3. Product Introduction & Engineering Value
When a NABCO M-800-II main engine control cabinet loses a board, the MCA-001-11 is the exact PCB that restores the original control path. It is a genuine NABCO printed circuit board identified by the cross-reference 885/73748378 and commonly marked K0170025.
Marine engineers keep tested units on hand because the board drops into the existing chassis without forcing a platform change. The surrounding engine control logic remains untouched, so the vessel returns to full remote-control capability with minimal downtime.
4. Technical Specifications
Manufacturer: NABCO
Part Number: MCA-001-11
Alternate Reference: 885/73748378
Additional Marking: K0170025
Product Type: Printed Circuit Board (PCB) / Control Card
Typical Weight: Approximately 770 g
Primary Application: Main engine remote control systems (M-800-II and related)
Current Type: DC
Form Factor: Industrial / marine PCB card
Exact voltage ratings, connector pin-outs, and I/O mapping are system-specific. Always verify against the original board and the applicable NABCO system documentation before installation.
5. Field Application & The “Trench” Experience
A bulk carrier’s main engine remote control station developed a fault on the MCA-001-11 board during a long voyage. The shipyard staged a tested replacement, matched the 885/73748378 reference and connector layout, and restored full telegraph and remote functions before the next port call. No reprogramming of the higher-level M-800-II logic was required.
Niche applications still using this board:
- NABCO M-800-II main engine remote control cabinets on commercial vessels.
- Marine engine control systems that retain the original MCA-series PCB architecture.
- Bridge-to-engine telegraph and remote-control interfaces built around NABCO electronics.

6. Transparency SOP: QA & Testing
Every MCA-001-11 is processed under the same sequence. The board first receives a full visual inspection for component condition, connector integrity, and correct part markings. It is then powered in a controlled fixture and exercised through functional checks against known-good reference points. Critical signal paths and connector continuity are verified. After functional confirmation the unit is cleaned, labeled, and released for shipment. Refurbished boards follow the identical process after any necessary component-level repair.
7. The Veteran’s Tech Trap Guide
⚠️ Cross-reference alone is not enough. The 885/73748378 marking appears on related MCA boards. Confirm the full MCA-001-11 designation and any secondary stamps (such as K0170025) against the original unit.
PRO TIP: These marine control boards are sensitive to moisture and salt air. Inspect the edge connectors carefully for corrosion before installation; a lightly oxidized contact can create intermittent faults that only appear under load.
⚠️ Do not mix MCA-001-11 with other MCA-series cards (MCA-101-11, MCA-203-11, etc.). They are not interchangeable and will produce control errors that look like upstream system problems.
8. Dynamic FAQ
Q: Is the available as new surplus? A: Yes. Both new surplus and fully tested refurbished units are stocked.
Q: Is this board used only in the M-800-II system? A: It is a core component of the NABCO M-800-II main engine remote control system and related marine control cabinets.
Q: Does installation require programming or calibration? A: In most cases the board is a direct hardware replacement. System-specific checks or calibration may still be required after the swap.
Q: What testing is performed before shipment? A: Visual inspection, powered functional checks, connector continuity, and signal-path verification under controlled conditions.
Q: What warranty is provided? A: Standard one-year coverage on both new surplus and refurbished boards against defects in materials and workmanship under normal marine or industrial use.
Q: Are detailed electrical schematics available? A: Public documentation is limited. Best practice is to compare the replacement board side-by-side with the original and consult the specific NABCO system manual for the application.
