Core Function AINT-14C is an upgraded high-density fiber communication PCB exclusively designed for ABB ACS800 multi-drive cabinets, acting as the galvanically isolated bridge between the CUVC main control board and power unit stacks: Transmits high-speed PWM IGBT drive trigger signals via 8 ST-type fiber ports to rectifier/inverter power modules; eliminates high-voltage EMI noise between low-voltage control and high-power circuits. Collects multi-channel real-time feedback signals: DC bus voltage, motor phase current, power unit temperature, IGBT fault flags, and short-circuit detection data. Supports synchronous multi-drive linkage for coordinated heavy-load motion (rolling mills, cranes, paper machines) with improved signal synchronization vs AINT-12C. Typical Industrial Applications Me
