Beckhoff EL3214-0090 | EtherCAT Terminal, 4-channel analog input, temperature

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.
