Product Overview
The ISIC PCM4-845 is a rugged 3U marine-certified industrial computer engineered for shipboard automation, navigation and machinery monitoring systems. Designed and manufactured in Denmark, this embedded computing platform addresses reliability limitations of standard commercial PCs exposed to engine room vibration, humidity and fluctuating DC power supplies. Ship operators, marine automation integrators and vessel maintenance teams rely on ISIC hardware for long-term stable operation of legacy marine software, including embedded Windows XP-based monitoring and control applications. This unit delivers flexible expansion capability and robust EMC performance, supporting continuous data acquisition, vessel system visualisation and communication with onboard PLC and instrumentation networks.

Key Functions
- Harsh Environment Embedded Computing: The ruggedised chassis and wide DC input range stabilise operation under marine vibration, temperature swings and power transients. It avoids unexpected shutdowns common with consumer-grade computers in engine room and wheelhouse environments.
- Multi-Interface Marine Data Gateway: Integrated Ethernet, serial and USB ports enable bidirectional data exchange between navigation equipment, propulsion monitoring sensors and vessel automation systems. It consolidates disparate field data for centralised logging and display.
- Legacy Software Compatibility: Optimised to run Windows XP Embedded, the ISIC marine computer maintains support for older marine monitoring applications that cannot be migrated to newer operating systems, extending service life of existing vessel control infrastructure.
- Expandable I/O Architecture: Standard PCI and PCIe internal expansion slots allow technicians to add specialised communication or signal acquisition cards, adapting the platform to custom retrofit automation requirements without full system replacement.
Application Scenarios
- Vessel Engine Room Monitoring Systems: Deployed to collect and process main engine, generator and auxiliary machinery sensor data. The PCM4-845 runs onboard condition monitoring software, tracking temperatures, pressures and vibration to support predictive maintenance for seagoing cargo vessels.
- Marine Automation Retrofit Projects: Widely used during ship refits to replace end-of-life marine computers. ISIC’s consistent mechanical form factor simplifies cabinet integration while preserving compatibility with existing wiring and legacy marine control software.
- Offshore Support Vessel Onboard Data Logging: Installed on supply and construction vessels to record operational parameters, propulsion loads and environmental data. Recorded logs support regulatory reporting, fuel consumption analysis and charter performance audits.
