3. Product Introduction & Engineering Value
The MCB-1101-01 is a NABCO/Nabtesco printed circuit board that forms part of the main engine remote control architecture. When this card fails, remote command and telegraph functions can drop offline.
It is a direct hardware replacement within the MCB-series family used on commercial vessels. A tested unit restores the original control path without requiring a full system redesign or software rewrite of the higher-level engine control logic.
4. Technical Specifications
Manufacturer: NABCO / Nabtesco
Part Number: MCB-1101-01
Product Type: Printed Circuit Board (PCB) / Control Card
Primary Application: Main Engine Remote Control systems
Form Factor: Industrial / marine PCB card
Related Family Boards: MCB-1201-01, MCB-1202-01, MCB-1302-01, MCB-1701-01
Exact voltage ratings, connector pin-outs, and signal assignments are system-specific. Always compare the replacement board to the original unit and the applicable system documentation before installation.
5. Field Application & The “Trench” Experience
A bulk carrier lost remote engine control capability when the MCB-1101-01 board developed an intermittent fault. The shipyard staged a verified replacement, matched the connector layout and part markings, and restored full bridge-to-engine command before the next port call. No changes to the surrounding control logic were required.
Typical remaining applications:
- NABCO/Nabtesco main engine remote control cabinets on commercial vessels.
- Marine engine telegraph and remote-control interfaces built around the MCB-series architecture.
- Engine control systems that retain the original NABCO M-800 family electronics.
6. Transparency SOP: QA & Testing
- Full visual inspection of the board surface, components, edge connectors, and part markings.
- Powered functional test in a controlled fixture against known-good reference points.
- Continuity and signal-path verification on critical connectors.
- Final cleaning, labeling, and release for shipment.
Refurbished boards receive the same sequence after any necessary component-level repair.

7. The Veteran’s Tech Trap Guide
⚠️ Do not interchange MCB-1101-01 with MCB-1201-01 or MCB-1302-01. These boards look similar but serve different functions within the control cabinet. Confirm the exact model number before power-up.
PRO TIP: Edge connectors on marine boards are prone to corrosion from salt air. Clean and inspect them carefully; a thin oxide layer can create intermittent faults that only appear under vibration or load.
⚠️ Always isolate power and discharge residual voltage before swapping the board. Hot-swapping can damage both the replacement and the surrounding backplane.
8. Dynamic FAQ
Q: Is the MCB-1101-01 available as new surplus? A: Yes. Both new surplus and fully tested refurbished units are stocked.
Q: Is this board part of the same family as the MCA-series cards? A: It belongs to the related MCB-series used in NABCO/Nabtesco main engine remote control systems, which often share the same control cabinets as MCA boards.
Q: Does installation require programming? A: In most cases the board is a direct hardware replacement. System-specific checks 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 schematics available? A: Public documentation is limited. Best practice is to compare the replacement side-by-side with the original board and consult the specific NABCO/Nabtesco system manual for the application.
