The EL3214-0090 is the TwinSAFE SC version of the EL3214. The EL3214-0090 analog input terminal facilitates the direct connection of four resistance sensors. The measured resistance value can either be output directly in ohms or transformed into a temperature. If the temperature at the measuring point is of interest, the conversion from resistance to temperature can be carried out in the terminal according to various sensor characteristics (Pt100, Pt1000, NI120, NI1000, KTY types, etc.). The EL3214-0090 can operate sensors using 2-wire and 3-wire technology. The EtherCAT Terminals indicate their measurement capability by means of light emitting diodes and status bits in the EtherCAT process image. The EL3214-0090 supports TwinSAFE Single Channel technology.

The TwinSAFE SC technology (TwinSAFE Single Channel) facilitates the use of standard signals for safety-related tasks in any networks or fieldbuses. To do this, EtherCAT I/Os from the areas of analog input, angle and displacement measurement, or communication (4 to 20 mA, incremental encoder, IO-Link, etc.) are extended by the TwinSAFE SC function. The typical signal features and standard functionalities of the I/O components are retained. TwinSAFE SC I/Os have a yellow strip at the front of the housing to distinguish them from standard I/Os.

The TwinSAFE SC technology facilitates communication by means of a TwinSAFE protocol. These connections can be distinguished from the usual safe communication by means of Safety over EtherCAT.

The data from the TwinSAFE SC components is transferred by means of a TwinSAFE protocol to the TwinSAFE Logic, where it can be used in the context of safety-relevant applications. Detailed examples for the correct application of the TwinSAFE SC components and the respective normative classification, which have been confirmed/calculated by TÜV SÜD, can be found in the TwinSAFE application manual.
