WARTSILA CCM-20

Product Overview The WARTSILA CCM-20 Central Control and Communication Module is a marine rack-mounted core control unit designed for Wartsila UNIC engine automation system, compatible with Wartsila 20 series diesel and dual-fuel marine engines, designed to comply with DNV marine type approval and IEC 60945 marine EMC standards. Built for real-time engine sensor data acquisition, actuator & cylinder combustion control & inter-module communication coordination, this robust marine controller withstands engine control room salt mist, continuous mechanical vibration and wide temperature fluctuation, delivers stable 24/7 continuous operation, and works cooperatively with ESM-20 engine protection module for merchant vessels, offshore supply vessels and FPSOs equipped with Wartsila main and auxiliary engines.

Featuring high-speed embedded real-time processor, multi analog and digital signal channels, redundant CAN bus, RS485 and Ethernet communication interfaces & front LED diagnostic indicators. It adopts standard ECR cabinet rack mounting, adapting to limited installation space inside marine engine automation racks. The modular assembly allows separate replacement of the CCM-20 module without full engine shutdown, greatly reducing equipment downtime for service. Equipped with built-in watchdog circuit, non-volatile fault data logging & overvoltage and short-circuit protection, mature hardware structure prevents signal interference and guarantees dependable engine real-time control performance during continuous duty.

For dependable real-time engine sensor data acquisition, actuator & cylinder combustion control & inter-module communication coordination, CCM-20 continuously collects pressure, temperature and crank speed signals from engine sensors, executes fuel injection and cylinder combustion control logic, exchanges data with ESM-20 safety module and vessel monitoring system. Reliable real-time engine sensor data acquisition, actuator & cylinder combustion control & inter-module communication coordination, premium marine-grade electronic components provide excellent humidity and salt fog resistance, extending service life in harsh marine engine control room working environments. Practical built-in watchdog circuit, non-volatile fault data logging & overvoltage and short-circuit protection, recorded fault information helps technicians quickly locate engine control anomalies during maintenance.

During continuous real-time engine sensor data acquisition, actuator & cylinder combustion control & inter-module communication coordination, this control module is fully compatible with WARTSILA UNIC engine management and vessel alarm monitoring automation platforms. Stable real-time engine sensor data acquisition, actuator & cylinder combustion control & inter-module communication coordination, mature Wartsila CCM-20 marine engine control technology with easy spare parts replacement and convenient after-sales maintenance. Robust built-in watchdog circuit, non-volatile fault data logging & overvoltage and short-circuit protection, simplifies engine control rack layout and reduces installation workload for vessel Wartsila engine retrofitting and machinery control system overhaul projects.
