ISO-P32C32Isolated Digital I/O Board

Functional Description
The ISO-P32C32 has 32 channels of optically isolated digital inputs and 32-channels of optically isolated digital outputs, arranged into four isolated banks. Each input chanel use a photo-coupler input which allows either internal power supply or external power selected by jumper. Isolated input channels 0~15 are designed into group A, channels 16~31 are designed 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 interface to field logic signals, eliminating ground-loop problems and isolating the host computer from damaging voltages. The ISO-P32C32has one 37-pin D-sub connector ans one 40-pin header. The 40-pin to D-sub 37 flat cable is used to fixed with the case. The user can connect the digital signal through the second D-sub connector. Each D-sub connector contains 16inputs chnnel and 16 output channel.
