The Advantech PCIe-1730 is a 32-channel isolated digital I/O PCIe card designed for industrial automation, machine control, and process monitoring. It combines 16 TTL digital I/O channels with 16 optically isolated digital I/O channels, delivering 2,500 VDC isolation protection against voltage surges and ground loops. The card interfaces via PCI Express v1.0 and connects through one DB37 female connector and four 20-pin box headers.
