IO-Link box with four configurable analog differential inputs
The EP3174-0002 and ERI3174-0002 IO-Link boxes 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.
