The EL3453-0090 offers the “ExtendedRange” feature enabling the use

of the full technical measuring range, which equals 130% of the specified

nominal measuring range.

In addition, the EL3453-0090 comes with the option of transmitting the

times of the last voltage and current zero crossing to the controller via

XFC technology. This can be used, for example, to carry out switching

operations to suit the application.

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 EL3475 is a 12-channel analog input that, with a 24-bit resolution

and an input voltage of 333 mV, enables simple and detailed

measurements in supply networks. With four RJ45 connections that

can each connect three current and/or voltage transformers, the EL3475

is multi-functional and the ideal solution for keeping installation simple

in demanding applications.

In combination with the SCL6xxx pluggable low power split-core

transformers, the EL3475 enables configuration-free commissioning,

as the current transformer ratios are set automatically between the

transformer and terminal during start-up thanks to the electronic

nameplate.

With a single voltage transformer in the system, several EL3475

EtherCAT Terminals can work together as a distributed power 

measurement system and perform any number of power measurements

without any loss in performance.

The EL3453-0120 EtherCAT power measurement terminal has voltage

inputs for up to 130 V AC for connecting voltage transducers, enabling

the monitoring of medium-voltage systems, for example.

The four current inputs are electrically isolated so that the terminal can

be used in all common grounded current transformer configurations

such as 2- or 3-transformer configurations with star or delta connection

incl. neutral conductor current measurement. The EL3453-0120 can be

used for simple grid analysis up to the 63rd harmonics analysis.

Alternatively, all readings can be combined in a power quality factor for

simplified diagnostics. Like all measured terminal data, the harmonic

content can be read via the process data. The EL3453-0120 offers the

“ExtendedRange” feature enabling the use of the full technical measuring

range, which equals 130% of the specified nominal measuring range.

In addition, the EL3453-0120 comes with the option of transmitting the

times of the last voltage and current zero crossing to the controller via

XFC technology. This can be used, for example, to carry out switching

operations to suit the application.

The EL3446-0011 EtherCAT Terminal enables measurement of

all relevant electrical data in the supply grid and performs simple

pre-evaluations. Since the EL3446-0011 itself has no voltage

inputs, the measured voltage values are transmitted via EtherCAT

from an EL3443 to be installed once per network.

The current in the connectable phases – of which there are up

to six – is fed in via simple current transformers. All measured

currents and voltages are available as RMS values. 

In the EL3446-0011. the active power and the energy consumption

for each phase are calculated. RMS values are available for voltage

U and current I as well as active power P, apparent power S,

reactive power Q, frequency f, phase shift angle cos φ, and

harmonics. The EL3446-0011 offers options for comprehensive

network analysis and energy management.

With 100 mA inputs, the EL3446-0011 is particularly suitable for

evaluating differential current transformers (such as the SCT4xxx)

and DC-capable current transformers.
