The EL3314-0090 analog input terminal allows four thermocouples

to be connected directly. The EtherCAT Terminal circuit can operate

thermocouple sensors using the 2-wire technology.

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 terminal.

The EL3314-0090 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 TÜV SÜD for the correct application of the TwinSAFE SC

components and the respective normative classifications can be found

in the TwinSAFE application manual.
