MAK 1.00.7-36.21.00-14 MAIN CONTROL PCB, 9.01.7-91.21.00-16 MONITOR PCB, 9.01.7-94.01.00 INTERFACE PCB
MAK set of 3 rack plug-in marine diesel engine control printed circuit boards, designed for Krupp Mak marine main / auxiliary diesel engine monitoring and governor speed control system, widely fitted onboard cargo vessels, offshore DP vessels and heavy-lift ships for engine signal acquisition, speed governing and safety protection control. This marine PCB group consists of 1.00.7-36.21.00-14 main control board, 9.01.7-91.21.00-16 engine monitor board and 9.01.7-94.01.00 interface board, working together to collect engine speed, exhaust temperature, lubrication oil pressure and cooling water temperature sensor signals, compute fuel control output and execute overspeed / low oil pressure emergency trip protection for marine diesel engines.

The marine PCB suite integrates multi-channel analogue evaluation circuits, watchdog monitoring, surge protection and front-panel LED status indicators, supports engine parameter calibration, fault event logging and safety interlock logic complying with marine classification society requirements for marine propulsion engine supervision. Its diesel engine control & hardware diagnostics function continuously monitors 24V DC power supply, field sensor wiring and backplane bus integrity, detects sensor signal loss, circuit drift and hardware component failure, transmits PCB fault alerts and diesel engine operating status to vessel AMS alarm console. The diesel engine control & hardware diagnostics ensures comprehensive monitoring and speed governing protection for MAK marine diesel engine control system. It enables reliable marine MAK PCB set operation under heavy vessel vibration and salt mist marine environments.

This MAK PCB group delivers stable marine diesel engine governing and monitoring performance installed inside vessel engine control cabinet. The diesel engine control & hardware diagnostics adopts marine-grade PCB substrate with EMC shielding against electromagnetic interference and mechanical shock. Marine propulsion technicians rely on these MAK PCBs operation to test speed loop response, verify sensor signal processing and inspect board communication during routine maintenance. It adopts standard rack edge plug-in connector design for straightforward spare replacement and minimal marine main engine control system downtime. Internal circuit boards use conformal coating to protect electronic components against salt mist, oil mist, condensation and temperature fluctuation. It works cooperatively with engine speed pick-up sensor, fuel actuator and ship integrated alarm monitoring system. It is widely used as engine control spare hardware for MAK marine vessel main diesel engine speed regulation and safety monitoring control system maintenance and retrofit projects.
