IP3112-Bxxx, IE3112

4 Channel Analog Input, from 0 to 20 mA

The IP3112 analog input module handles signals in the range from 0 to 20 mA. The input current is digitized to a resolution of 16 bits (the default is 15 bits), and is transmitted, electrically isolated, to the higher-level automation device. The input channels have differential inputs and possess a common, internal ground potential. The applied load voltage (which can be any value up to 30 VDC) is fed through to supply the sensor. The module is quite versatile, but default settings have been selected in such a way that in most cases it is not necessary to perform configuration. The input filter and associated conversion times can be set within a wide range, and several data output formats may be chosen. The inputs can, if required, be scaled differently, and automatic limit monitoring is also available. Parameterization may be carried out either via the fieldbus or, using the KS2000 software tool, through the configuration interface. The parameters are stored in the module.
