ABB BINT-22C Power Module Interface Signal Board, Order Code 3AUA0000078551 Core Function: This high-channel isolation interface PCB acts as the signal bridge between ACS880 multi-drive BCU control units and parallel power inverter modules. It transmits isolated IGBT gate drive feedback, DC bus voltage sampling, multi-channel power module thermistor temperature signals, short-circuit fault detection, and ground fault monitoring data. Integrated reinforced galvanic isolation blocks high-voltage switching noise from interfering with low-voltage control circuits. The board aggregates fault signals from multiple parallel power stacks, feeds diagnostic data to the main CPU, and features dedicated LED status indicators for each power module channel to speed troubleshooting of parallel multi-inve
