ISO-P32S32W has 32 channels of optical-isolated DI and 32 channels of optical-isolated open-collector output board (8-channel for 500 mA and 24-channel for 100 mA current sinking output, NPN), arranged into four isolated banks. Each input channel use a photo-coupler to isolate the card and computer from external signal. Each digital output offers a NPN transistor and integral suppression diode for inductive load. ISO-P32S32W requires external power to drive the D/I and D/O ports.

This interface board is easily installed in any PC. The board interface to field logic signals, eliminating ground-loop problems and isolating the host computer from damaging voltages. ISO-P32S32W has one 37-pin D-Sub connector and one 40-pin male header. The 40-pin to DB-37 flat cable is used to fix with the case. The user can connect the digital signal through the second D-Sub connector. Each D-Sub connector contains 16 input channels and 16 output channels
