Beckhoff EL3475-0200 | EtherCAT Terminal, 12-channel analog input, 4-port, multi-function

The EL3453-0100 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 EL3453-0100 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 EL3453-0100 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 EL3453-0100 comes with the option of transmitting the

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

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

operations to suit the application.

The EL3453 EtherCAT power measurement terminal has voltage

inputs for direct monitoring of high-capacity generators up to max.

690 V AC, as is common in the wind industry, for example.

No upstream voltage transformer is required. 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 connectionz

incl. neutral conductor current measurement.

The EL3443-0013 EtherCAT Terminal enables the measurement

of all relevant electrical data of the supply network and carries

out simple pre-evaluation. The voltage is measured via direct

connection of L1. L2. L3 and N. The current of the three phases

L1. L2 and L3 is fed via simple current transformers.

All measured currents and voltages are available as root-mean-

square values. In the EL3443-0013 terminal, the effective power

and energy consumption for each phase are calculated.
