Introduction

4-channel input thermocouple, TwinSAFE SC

The EJ3314-0090 EtherCAT module enables the direct connection of four thermocouples. The circuit of the EtherCAT module can operate thermocouple sensors in 2-wire technology. A microprocessor handles linearization across the whole temperature range, which is freely selectable. Cold junction compensation is achieved by external temperature measurement via RTDs. Measurements in the mV range are also possible with the EJ3314-0090 EtherCAT plug-in module.

The EJ3314-0090 also supports TwinSAFE SC (TwinSAFE Single Channel). This enables the use of standard signals for safety tasks in any networks or fieldbuses.
