This product is an Ethernet-compliant digital I/O Unit used to provide a digital signal I/O function from PC LAN port. Digital signals can be input and output at 12 - 24VDC. 16 channels of Optocoupler isolated inputs (compatible with both current sink and current source outputs) and 16 channels of Optocoupler isolated open-collector outputs (compatible with current sink type) are equipped. Also, including a digital filter function which prevents wrong recognition of input signals, output transistor protection circuit (surge voltage protection and over current protection), and the fail-safe function which changes outputting to the specified pattern when communication errors occur.
