The 96-Channel Digital Input/Output (I/O) Board provides 48 opto-isolated digital output channels as well as 48 opto-isolated digital input channels on a single 3U VPX board. A Field-Programmable Gate Array (FPGA) and a PCIe bridge is used to provide access to the digital data over the PCIe interface.

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

Architecture

A FPGA is used to control the 48 output channels and read the 48 input channels, and provides the PCI interface to the PCIe bridge. LED optocouplers on all input and output channels provide 2 500 V RMS isolation, while outputs are driven by high-voltage Darlington transistor arrays.
