PCI Digital I/O Boards

PISO-P32C32U - ICP DAS USA, Inc. (ICP DAS)

The PISO-P32C32/P32C32U/P32C32U-5V has 32 channels of optically isolated digital inputs and 32 channels of optically isolated digital outputs, arranged into four isolated banks. Each input channel uses a photo-coupler input which allows either internal isolated power supply or external power selected by jumper. Each digital output offers a Darlington transistor. The power supply of the input port may use the external power or the power from the PC side via DC/DC converter. The power supply of the output port should use the external power. The board eliminates ground-loop problems and isolates the host computer from damaging voltages.
