The DIO-32 PCIe digital-I/O-interface adapter provides 16 optically isolated inputs and 16 Reed-relay outputs. Isolated inputs protect PCs and sensitive equipment from voltage spikes and ground-loop currents in industrial environments. The socketed DIP resistors allow for configurable input ranges of 2 to 30V. The outputs provide long-life, dry-contact switch closures for low-current applications. Available in 3 to 13V or 10 to 30V inputs, the adapter costs $479.
