PDF print version of this specification

The 64-Channel Digital Input/Output (I/O) Board provides 32 opto-isolated digital output channels, each with internal output status feedback, as well as 32 opto-isolated digital input channels on a single 3U CompactPCI board. A Field-Programmable Gate Array (FPGA) is used to provide access to the digital data over the PCI bus. The 32 output status feedback channels can be used as additional inputs giving a 96-channel board.

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

Architecture

A FPGA is used to control the 32 output channels and read the 32 input channels, and provides the PCI interface. LED optocouplers on all input and output channels provide 2 500 V RMS isolation, while outputs are driven by high-voltage Darlington transistor arrays.
