Description
Product Introduction & Engineering Value
A main engine remote control system depends on reliable signal handling between bridge commands, control logic, and engine-side equipment. The NABCO MCB-1202-01 is a dedicated control box PCB designed for engineers maintaining existing NABCO 800III propulsion automation systems.
This board is commonly maintained as a replacement spare for vessels operating legacy NABCO engine control installations. Accurate identification is critical because MCB-series boards can share similar mechanical formats while performing different control functions.

Field Application & The “Trench” Experience
A bulk carrier operating with a NABCO 800III main engine remote control system began showing intermittent command response problems during maneuvering preparation. The bridge control commands were transmitted correctly, but the engine-side control cabinet occasionally failed to respond as expected.
The maintenance team first checked external wiring, terminal connections, and field devices. After eliminating those causes, attention moved to the Main Engine Control Box PCB assemblies. The failed board was identified as an MCB-1202-01. A replacement card was inspected, installed, and verified through operational testing.
The vessel returned to normal maneuvering capability without replacing the complete remote control system.
Typical application scenarios:
- NABCO 800III Main Engine Remote Control maintenance
- M/E Control Box PCB replacement
- Marine propulsion automation spare inventory management
- Shipyard overhaul projects requiring original NABCO electronics
MCB-1202-01
Transparency SOP: QA & Testing
A replacement MCB-1202-01 should pass controlled inspection before being installed into a propulsion control system.
Quality verification process:
1. Identification Confirmation
- Verify NABCO/Nabtesco marking.
- Confirm MCB-1202-01 model.
- Check PCB labels and revision information.
2. Physical Condition Review
- Inspect PCB surface and components.
- Check connectors and terminals.
- Look for corrosion, contamination, or storage damage.
3. Electrical Evaluation
- Perform applicable continuity checks.
- Inspect power-related sections.
- Verify no visible component failure.
4. Final Spare Preparation
- Package using ESD protection.
- Record inspection results.
- Maintain traceable inventory records.
The Veteran’s Tech Trap Guide
⚠️ Do not confuse with MCB-1201-01.
Both belong to the NABCO MCB family, but they are separate control box boards. Replacement should follow the installed equipment documentation.
⚠️ Confirm the complete model number before purchase.
A missing digit or incorrect suffix can result in receiving a board designed for another control function.
⚠️ PRO TIP: Record all terminal and connector positions before removal.
Main engine control boxes often contain multiple harness connections. A simple photo record can prevent incorrect reconnection.
⚠️ Test the complete control sequence after installation.
A PCB that powers up correctly may still fail under actual command conditions.
