ISA Isolated Digital I/O Boards

ISO-P32C32 - ICP DAS USA, Inc. (ICP DAS)

The ISO-P32C32 is a 64-channel isolated digital input board, arranged into four isolated banks. Each input chanel use a photo-coupler input which allows either internal power supply or external power selected by a jumper. Isolated input channels 0 ~15 are designed into group A, channels 16~31 into group B, Isolated input channels 32~47 are into group A, channels 48~63 are into group B. The power supply of the input port may use the external power or the the power from the PC side using DC to DC converter. The board interfaces to field logic signals, which eliminates ground-loop problems and isolates the host computer from damaging voltages. The ISO-P32C32 has one 37-pin D-sub connector and one 40-pin header. Users can connect the digital signal through the second D-sub connector. Each D-sub connector contains 16 input channels and 16 output channels.
