96-Channel Isolated Digital I/O 3U VPX Board
 

PDF print version of this specification

The 96-Channel Digital Input / Output (I/O) Board provides up to 96 opto-isolated digital input and output channels with internal output status feedback on a single 3U VPX board.

All 96 digital channels may be configured at build time as either digital inputs, digital outputs, internal output status feedbacks or as a combination of all three. The high current digital output channels can sink up to 600 mA. A Field-Programmable Gate Array (FPGA) and a PCI to PCIe bridge are used to provide access to the digital data over the PCIe bus.

I/O channel isolation voltage is 2 500 V RMS with 500 V RMS isolation voltage across the VPX backplane connectors.

Architecture

A FPGA is used to control the output channels and read the input channels as well as providing the PCI interface to the PCIe bridge. LED optocouplers on all inputs and outputs provide 2 500 V RMS isolation and the outputs are driven by high-current optical coupled MOSFETs.

Features

  • I/O channel to system voltage isolation
  • high number of digital inputs and digital outputs
  • high output sink current (up to 600 mA)
  • board identification switch
  • programmable inputs and outputs
  • Commercial, Industrial and Ruggedised grades
