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.

4-wire technology, external bridges must be set for the 2- and 3-wire

The EL3184 analog input terminal for HART-capable field devices

supplies measuring transducers located in the field and transmits

their analog measuring signals to the automation device under

electrical isolation. With a technical measuring range of 107%

of the nominal range, the terminal also supports commissioning

with sensor values in the limit range and the evaluation according

to NAMUR NE43.

HART communication can also be used for the FDT/DTM concept.

The TwinCAT FDT Container enables field device DTMs to be 

directly integrated into TwinCAT Engineering.

This means that field device configuration and diagnostics are

already available in the development environment.

As the FDT concept only supports 32-bit, it cannot be used in the

64-bit TwinCAT XAE Shell.

The EL3182 analog input terminal for HART-capable field devices

supplies measuring transducers located in the field and transmits

their analog measuring signals electrically isolated to the

automation device. With a technical measuring range of 107% of

the nominal range, the terminal also supports commissioning with

sensor values in the limit range and the evaluation according to

NAMUR NE43.

The EtherCAT Terminal indicates the signal state by means of light

emitting diodes. Error LEDs signal overload and wire breakage, in

addition to which LEDs provide information about the state of the

HART communication and signal any communication errors.

The HART (Highway Addressable Remote Transducer) protocol

enables two-way communication through digital data transfer via

the analog 0/4…20 mA wiring. In this way, in addition to the analog

current signal, further data can be exchanged with the field device

via the superimposed digital signal.

The HART communication can also be used for the FDT/DTM concept.

The TwinCAT FDT container enables the integration of field device DTMs

into TwinCAT Engineering, so that the device configuration and diagnostic

functions are available directly within the development environment.

As the FDT concept only supports 32-bit, it cannot be used in the 64-bit

TwinCAT XAE Shell.

The EL3174 analog input terminal has four individually parameterizable inputs.

Signals in the range from -10/0 to +10 V or-20/0/+4 to +20 mA can be

processed via each channel. Physically, the voltage and current signals

should be connected to different terminal points.

Each channel should then be set by the controller/TwinCAT to U or I mode

via CoE. The voltage inputs operate differentially; the current inputs are

single-ended. All inputs are digitized with a resolution of 16 bits and

transmitted, electrically isolated, to the higher-level automation device.

With a technical measuring range of ±107% of the nominal range, the

terminal also supports commissioning with sensor values in the limit

range and diagnostics according to NAMUR NE43.

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.
