Introduction
IO-Link box with four configurable analog differential inputs
The EPI3174-0002 und ERI3174-0002 IO-Link box modules have four analog inputs which can be individually parameterized, so that they process signals either in the -10 V to +10 V range or the 0/4 mA…20 mA range. The voltage or input current is digitized with a resolution of 16 bits, and is transmitted (electrically isolated) to the higher-level automation device.
The four input channels have differential inputs and possess a common, internal ground potential. The input filter and therefore the conversion times are configurable in a wide range. The inputs can, if required, be scaled differently, and automatic limit value monitoring is also available. Parameterization is done via IO-Link. The parameters are stored in the module.
The IO-Link box modules with die-cast zinc housing (ERI series) can be used in extremely challenging industrial and process environments. The fully sealed design and the metal surface of the ERI series make it ideal for applications requiring enhanced load capacity and protection against welding spatter, for example.
