IE3102 | Extension Box, 4-channel analog input, voltage, ±10 V, 16 bit, differential, M12

The IE3102 analog input module handles signals in the range from -10 to +10 V. The voltage is digitized to 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 applied auxiliary voltage (which can be any value up to 30 V DC) is fed through to supply the sensor. It is thus possible, for instance, to supply a measuring potentiometer with 10 V DC from an external voltage source.

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.
