Introduction

4-channel analog input, temperature, RTD (Pt100), 16 bit, 3-wire connection, TwinSAFE SC

The EL3214-0090 is the TwinSAFE-SC version of the EL3214.

The EL3214-0090 analog input terminal allows 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 done in the terminal according to different sensor characteristics (Pt100, Pt1000, Ni120, Ni1000, KTY types and others).

The EL3214-0090 can operate sensors in 2- and 3-wire technology.

The EtherCAT Terminals indicate their measurement capability via LEDs and status bits in the EtherCAT process image.

The EL3214-0090 supports TwinSAFE single channel technology. 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 TÜV SÜD for the correct application of the TwinSAFE SC components and the respective normative classifications can be found in the TwinSAFE application manual.
