This product is a PCI Express card used to provide a digital signal I/O function on a PC. It is a 12 - 24VDC opto-coupler isolated type for which the response speed of 5µSec can be realized by using a high-speed opto-coupler with input 32ch and open-collector output 32ch equipped. You can use all of the input signals as interrupt inputs. Equipped with the digital filter function and output transistor protection circuit (surge voltage protection and overcurrent protection). Windows/Linux driver is bundled with this product. Possible to be used as a data recording device for LabVIEW, with dedicated libraries.
