This product is a PCI Express bus-compliant interface card used to provide a digital signal I/O function on a PC. This product is compatible with the digital signal I/O with high voltage (input 12 to 48VDC, output 120VAC/DC) and features 16 opto-coupler isolated inputs (compatible with current sink output/current source output) and 16 semiconductor-relay outputs. You can use 16 input signals as interrupt inputs. In addition, the digital filter function to prevent wrong recognition of input signals is provided. Windows/Linux driver is bundled with this product. Possible to be used as a data recording device for LabVIEW, with dedicated libraries.
