The EPI3188-0022 IO-Link box has eight analog inputs which can be individually parameterized, so that they process signals either in the ±10 V or the 0/4…±20 mA range. The voltage or input current is digitized with a resolution of 16 bit, and is transmitted (electrically isolated) to the higher-level automation device. The eight input channels have single-ended inputs and possess a common, internal ground potential. The input filter and therefore the conversion times are configurable in a wide range. If required, the inputs can be scaled differently, and automatic limit monitoring is also available.

The EPI3188-0022 is a Class B device, a 5-wire cable is required for connection.
