Beckhoff Automation ej3318

The EJ3318 EtherCAT plug-in module allows the direct connection of eight thermocouples and is therefore particularly well suited to compact applications on the signal distribution board. The module's circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable. The error LEDs indicate a broken wire. The compensation for the cold junction is done by two RTDs (Pt1000), which can be placed anywhere on the signal distribution board. The EJ3318 can also be used for mV measurements.
