The PISO-P32C32 has 32 channels of optically isolated digital inputs and 32 channels of optically isolated digital outputs, arranged into four isolated banks. Each input channel use a photo-coupler input which allows either internal isolated power supply or external power selected by jumper. Each digital output offers a darlington transistor and integral suppression diode for inductive load. Isolated input channels 0-15 are designed into group A and channels 16-31 are designed into group B. Isolated output channels are designed into group C and group D. The power supply of the input port may use the external power or the power from the PC side using DC/DC converter. The power supply of the output port should use the external power. This interface board is easily installed in any PC. The board interfaces to field logic signals, which eliminates ground-loop problems and isolates the host computer from damaging voltages. The PISO-P32C32 has one 37-pin D-Sub Connector and one 40-pin male 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.
