IE3202 | Extension Box, 4-channel analog input, temperature, RTD (Pt100), 16 bit, M12

The IE3202 analog input module allows resistance sensors to be connected directly. The module’s circuitry can operate the sensors using 2-, 3- or 4-wire connection techniques. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The module can also be used for simple resistance measurement with the output in ohms. The module’s standard settings are: resolution 0.1 °C in the temperature range of Pt100 sensors in 4-wire connection. Sensor malfunctions such as broken wires are indicated by error LEDs.

The module is quite versatile, but the default values are 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.
