The PCI Express bus-compliant interface board helps extend a computer's digital signal I/O functions. This is a DIO-3232L-PE model of a 12-24VDC opto-coupler isolated type. This particular device comes with a opto-coupler isolated input of 32ch and opto-coupler isolated open-collector output of 32ch.
Input signals can be used as interrupt inputs. The interface board is outfitted with the digital filter function and output transistor protection circuit. The latter is highly useful for surge voltage protection and overcurrent protection. This product also includes a Windows/Linux driver
