Beckhoff Automation ej3314-0090

The EJ3314-0090 EtherCAT plug-in module allows four thermocouples to be connected directly. The module circuit can operate thermocouple sensors using the 2-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable. Compensation for the cold junction is made through an internal temperature measurement at the module. The EJ3314-0090 can also be used for mV measurement. With the aid of the TwinSAFE?SC technology (TwinSAFE Single Channel) it is possible to make use of standard signals for safety tasks in any network or fieldbus. To do this, EtherCAT I/Os from the areas of analog input, position measurement or communication (4°≠20?mA, incremental encoder, IO-Link, etc.) are extended by the TwinSAFE?SC function. The properties typical for the signals and the standard functions of the I/O components are retained. TwinSAFE?SC I/Os differ optically from standard I/Os by a yellow stripe on the front of the housing. The TwinSAFE?SC technology enables communication via a TwinSAFE protocol. These connections can be distinguished from the usual secure communication via Safety over EtherCAT. The data from the TwinSAFE?SC components is fed via a TwinSAFE protocol to the TwinSAFE Logic, where it can be used in the context of safety-relevant applications. Detailed examples confirmed/calculated by the T®πV S®πD for the correct application of the TwinSAFE?SC components and the respective normative classifications can be found in the TwinSAFE application manual.
