Preliminary

PDF print version of this specification : A4 or Letter

The 32-Channel Isolated Digital Input adapter provides 32 opto-isolated digital input channels on a single PMC adapter. A Field-Programmable Gate Array (FPGA) is used to provide access to the digital data over the PCI bus.

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

Architecture

A FPGA is used to read the 32 input channels and provide the PCI interface. Isolation is achieved by optocouplers on all inputs.
