6U cPCI 256-Channel Isolated Digital I/O Board

The 256-Channel Digital Input/Output (I/O) Board provides 128 opto-isolated digital output channels, each with internal output status feedback, as well as 128 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 channels to system isolation is 2 500 V RMS.

Architecture

A set of FPGAs is used to control the 128 output channels and read the 128 input channels. Another FPGA is used to provide the PCI interface. Dual-LED optocouplers on all inputs and outputs provide voltage isolation, while outputs are driven by high-voltage Darlington transistor arrays.
