IP3312-Bxxx, IE3312

4 Channel Analog Input Thermocouple

The IP3312 analog input module permits four thermocouples to be directly connected. The module's circuit can operate thermocouple sensors using the 2-wire technique. 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 voltage measurements in the mV range. The module's standard settings are: Resolution 0.1 °C over the temperature range of type K sensors. Sensor malfunctions such as broken wires are indicated by error LEDs. Compensation for the cold junction is made through a temperature measurement in the connecting plug. This means that standard extension leads can be connected.

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.
