EP3204-0002 – BECKHOFF

EP3204-0002 | EtherCAT Box, 4-channel analog input, temperature, RTD (Pt100), 16 bit, M12
The EP3204-0002 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. 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 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. Parameterization is carried out via EtherCAT.
