EQ3204-0002 | 4-channel analog input PT100 (RTD)

The EQ3204 EtherCAT Box with analog inputs allows resistance sensors to be connected directly. The module’s circuitry can operate the sensors using 2-, 3- or 4-wire connection techniques. Linearisation over the full temperature range is realised 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 2-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. Parameterisation is carried out via EtherCAT.

The modules of the EQxxxx series are made of stainless steel and feature the “Hygienic Design” completely. Therefore they are ideal for applications in the food, chemical or pharmaceutical industries, which require protection class IP 69K.
