Working Principle
Deployed as distributed node in marine control network, receives master control command from H1111.0103 through redundant CAN FD bus, independently processes local auxiliary equipment sensor signals. It executes parallel generator power distribution, hydraulic actuator position closed-loop control and equipment fault threshold judgment; abnormal signals uploaded to main controller for centralized HMI display. Hardware protection circuit directly cuts output power when circuit overload occurs without waiting software response to avoid equipment burnout.
Material Composition & Structural Characteristics
- Sealed Enclosure: Die-cast aluminum alloy with polyurethane full sealing glue layer, IP67 waterproof dustproof
- Internal Circuitry: Anti-corrosion coated PCB, wide-temperature industrial-grade electronic components
- Cable Ports: Stainless steel compression cable glands with fluorine rubber sealing rings resistant to marine oil and seawater corrosion
- Structural Partition: Independent power cavity and signal control cavity separated by metal shielding partition to eliminate interference
Installation Requirements
- Installation Type: Wall-mounted or 19-inch cabinet rack fixed, four-corner bolt locking
- Outdoor Offshore Installation: Must install additional sunshade and rain shield cover to avoid direct sunlight heating
- Cable Routing: All signal and power cables use shielded marine multi-core cables, shielding layer single-end grounded at controller terminal
- Cabinet Air Circulation: For indoor cabinet installation, maintain continuous air flow to avoid enclosure internal heat accumulation
Application Scenarios
- Offshore oil platform auxiliary pump, fan, compressor distributed control
- Bulk carrier, container ship hatch cover, deck crane hydraulic system control
- Vessel diesel generator parallel operation load sharing automation
- Floating LNG storage tank auxiliary safety interlock control
- Coastal tugboat thruster auxiliary monitoring subsystem
Operation & Usage Precautions
- Strictly prohibit opening the sealed enclosure cover during powered operation; IP67 protection will be completely invalid after seal damage
- Cable glands must be fully tightened; loose glands will lead to seawater mist infiltration and internal circuit short circuit
- Do not connect inductive heavy load actuators without matched surge absorption terminals
- Quarterly inspection required for cable gland rubber sealing rings; replace aging cracked sealing parts timely
- Avoid long-term continuous operation at ambient temperature exceeding +60 °C, will accelerate internal capacitor aging
