The IP3112 analog input module handles signals in the range from 0/4 to 20В mA. The input current is digitized to a resolution of 16В bits (the default is 15В 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 applied auxiliary voltage (which can be any value up to 30В VВ DC) 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, several data output formats may be chosen. If required, the inputs can be scaled differently. 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.
