CAT MaK PD-N3000 Engine Main Control Protection Controller

CAT MaK PD-N3000 Engine Main Control Protection Controller

PD-N3000 is a CAT MaK marine diesel engine dedicated engine main control protection controller (ECU control unit), suitable for MaK medium speed marine engines and generator diesel engines.
The core function of PD-N3000 is to collect sensor signals such as engine speed, oil temperature, oil pressure, exhaust temperature, cylinder temperature, fuel pressure, etc., to complete speed closed-loop speed regulation and fuel injection control; Simultaneously integrating protection logic for overspeed, high temperature, low pressure, etc., to achieve fault alarm, fault shutdown, and SOE event recording; Support ship bus communication, upload operating parameters and alarm codes to the engine room monitoring system and upper SCADA. PD-N3000 is the core control and protection unit of MaK marine power system.

Product features

1. Developed specifically for MaK medium speed marine diesel engines, integrating speed regulation, monitoring, and protection into one to meet ship power safety regulations.
2. Multiple channels for analog, temperature RTD, switch, and speed acquisition can cover all measuring points of the engine.
3. Dual speed acquisition, independent circuit for overspeed protection, meeting the safety shutdown requirements of the classification society and preventing the risk of speeding.
4. Supports J1939 and Modbus protocols, and can be integrated with cabin monitoring systems, alarm systems, and remote monitoring platforms.
5. Equipped with SOE event sequence recording, accurately recording downtime and alarm timing, facilitating maritime accident review.
6. The circuit board is coated with three anti coatings, which are resistant to salt spray, moisture, and vibration, and are suitable for harsh working conditions such as high salt spray at sea.
7.  Equipped with specialized debugging software, supporting speed PID tuning, protection threshold setting, and fault code reading.
8.  The relay output can directly drive the shutdown solenoid valve, sound and light alarm, and fuel cut-off valve.
9. Possessing DNV and LR classification certifications, suitable for power plants of sea and inland vessels.
