The 128-Channel Digital Input/Output (I/O) Board provides 64 opto-isolated digital output channels, each with internal output status feedback, as well as 64 opto-isolated digital input channels on a single 6U CompactPCI board. Field-Programmable Gate Arrays (FPGAs) are used to provide access to the digital data over the PCI bus.

I/O channel to system isolation is 2 500 V RMS.

Architecture

A set of FPGAs is used to control the 64 output channels and read the 64 input channels. Another FPGA is used to provide the PCI interface. Dual-LED optocouplers on all inputs and ouputs provide voltage isolation, while outputs are driven by high-voltage Darlington transistor arrays.
