Material Composition Multi-layer high-density glass fiber PCB; Industrial grade main processor chip; SDRAM and flash memory chips; Aluminum alloy heat sink; Ethernet isolation transformers; Gold-plated VME edge connector; Lithium battery for real-time clock.
Structural Characteristics VME standard plug-in board; Gold finger connects to VME backplane; Front panel equipped with Ethernet, serial ports and status LED indicators; Aluminum heat sink mounted on main processor; Metal ejector latches for board insertion and extraction.
Working Principle Backplane provides power supply to controller board. The processor reads I/O data from backplane, runs turbine control and protection algorithms, outputs control commands to I/O modules. It transmits operating data and alarm events to HMI via Ethernet. Hardware watchdog monitors program running state, triggers system reset when program crash occurs.
Installation Requirements Cut off VME rack power before replacement. Wear anti-static wristband to insert board into VME slot and lock ejector latches. Connect Ethernet and serial cables on front panel. Download turbine control configuration after power-on, execute system self-test and verify communication. Ensure cabinet cooling fan works normally.
Usage Notes Do not remove onboard lithium battery arbitrarily. Backup turbine configuration before replacing board. Prevent scratches on gold-plated edge connector. Keep good cabinet ventilation to avoid overheating. Spare board must be stored in anti-static packaging.
