Material Composition: PCB substrate: Multi-layer FR4 glass fiber epoxy printed circuit board. PCB surface treatment: Full industrial conformal coating against moisture and salt fog corrosion. Core components: High precision analog front-end chip, ADC converter, bus communication processor. Front panel: Marine grade aluminum alloy front panel with LED indicators. Backplane connector: Gold plated copper alloy contact pins with anti-corrosion treatment. Terminal block: Marine grade PA66 flame retardant plastic terminal block for field sensor wiring.
Structural Features: Standard marine chassis single slot plug-in module structure. Aluminum alloy front panel with multiple LED indicators for power, channel status and fault alarm. Internal circuit divided into analog signal input conditioning area, ADC conversion area, digital processing area and backplane bus communication area. Mechanical locking buckle to fix module in marine chassis against vessel vibration. Isolation circuit between analog sensor input and digital system bus to reduce interference.
Working Principle: The module receives DC power supply from Kongsberg marine control chassis backplane. Temperature sensors transmit analog resistance or millivolt signal to module terminal block. Analog front-end circuit conditions the raw signal, ADC chip converts analog signal to digital value. For thermocouple input, cold junction compensation circuit compensates reference junction temperature. On-board processor calculates real temperature value, applies digital filtering, then sends temperature data and channel status to main controller via proprietary system bus. When sensor cable open or short circuit occurs, self-diagnosis circuit detects abnormality and upload fault alarm signal.
Installation Requirements: Cut off chassis power supply before inserting or removing module. Insert NA1077(TCI) module into designated slot of Kongsberg marine automation chassis and lock mechanical latch. Connect RTD and thermocouple sensor cables to module terminal block according to wiring diagram. Complete channel type configuration for each sensor channel before system commissioning. Marine control cabinet must connect reliable protective earth ground. Separate sensor signal cables and high-power power cables in different cable trays. Reserve ventilation space around module for heat dissipation inside cabinet.
Usage Notes: Hot swap operation is forbidden when marine control chassis is energized. Backup channel configuration parameters before module replacement or parameter modification. Use marine grade shielded twisted pair cable for temperature sensor wiring. Regularly inspect terminal block tightness and cable insulation condition under vessel vibration. Wear anti-static wristband during module maintenance and replacement. Do not scratch conformal coating on PCB surface. Prevent salt spray and moisture from entering cabinet enclosure.
