GFD233A103 3BH022294R0103

Power supply
Rack backplane power supply, rated 24VDC ± 15%, overall power consumption ≤ 5W
Built in reverse, overvoltage, and surge hardware protection
Fiber optic signal channel
Multi channel fiber optic transceiver circuit, transmitting PWM gate trigger pulse+power unit fault feedback signal
High and low voltage isolation withstand voltage: 5kV AC for 1 minute, completely isolating high voltage power side interference
Onboard I/O terminals
Plug in green terminal block, integrated with multiple DI/DO switch quantity acquisition: high-voltage cabinet door interlock, cooling fan, charging contactor, unit overtemperature signal
Backplane communication
ABB dedicated internal high-speed backplane bus, directly connected to GCC960C102/GCC960C103 main control board, without independent network port

Function
Signal distribution relay: Receive fiber optic drive instructions issued by the GCC960 main control and distribute them to all GDD series IGBT/IGCT drive boards of the entire machine
Fault summary collection: Collect all power unit short circuit, overcurrent, and overtemperature fiber fault feedback, upload to the main control to generate fault codes
Peripheral interlocking signal acquisition of cabinet: Processing peripheral switch values such as high-voltage cabinet safety doors, fans, contactors, etc., participating in the overall safety protection logic of the machine
Supporting equipment: ABB ACS1000, ACS2000 6kV/3kV medium voltage high-power frequency converter (power plant, mining, metallurgical main drive)
