GFD212A

Parameter
power supply specifications
Backplane bus power supply, rated 24VDC ± 15%, low-power design, overall power consumption<6W; supports reverse connection and overvoltage hardware protection
Fiber optic drive signal channel
Multiple fiber optic transceiver channels, isolated transmission of PWM trigger pulses issued by the main control, while collecting power unit fault feedback fiber optic signals
High and low voltage isolation withstand voltage: ≥ 5kV AC, completely isolating high voltage interference
Terminal I/O channel
External green plug-in terminal, integrated with multiple analog signal acquisition and digital DI/DO, used for cabinet temperature, cabinet door interlocking, contactor status acquisition and output
communication bus
Backplane dedicated high-speed bus docking with GCC960C102/C103 main control board; Onboard CAN2.0 bus, supporting Modbus and Profinet extended communication

Function
Signal transfer bridge: Connect the GCC960 main control board to the GDD360C/GDD471A001 power drive board, and distribute the light fiber gate trigger signal
Fault collection summary: Collect all power unit overcurrent, overtemperature, and short-circuit fault fiber feedback, upload to the main control to generate fault codes
Cabinet peripheral signal processing: collecting cooling fan, high-voltage cabinet door interlock, charging contactor, temperature sensor switch/analog signal
Closed loop current monitoring: dual channel high-precision current sampling, real-time monitoring of output current, participating in overload and short-circuit protection logic operations
