The EL3443-0010 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 EL3443-0010 terminal, the effective power

and energy consumption for each phase are calculated.

The RMS values of voltage U and current I as well as the active

power P, apparent power S, reactive power Q, frequency f, phase

shift angle cos φ and harmonic are available. The EL3443-0010

offers extended functionality for mains analysis and energy

management.

In addition, the EL3443-0010 comes with the option of transmitting

the time of the last voltage zero crossing to the controller via XFC

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

operations to suit the application.

The EL3443 can be ordered for other current ranges, such as 5 A,

100 mA or 333 mV. An overview of the different versions can be

The ED3362-0100 analog input terminal enables the direct connection

of two independent resistance bridges (strain gauges – SG) or load

cells using 4-wire or 6-wire connection technology. It records the ratio

of the bridge voltage UBridge to the measured supply voltage USense

and outputs the calculated load value as a process value based on the

terminal settings. This enables precise recording of weights, torques,

and vibrations.

Special features:

• integrated, switchable 5 V/10 V bridge supply UExc, generated from

the power contacts

• parallel connection of bridges possible due to powerful bridge supply

• sampling rate of 10 ksps

The ED series EtherCAT Terminals have push-in connection technology

which makes wiring easy and tool-free.

In addition, the terminal has two digital inputs/outputs. For example,

an input can be used to trigger a tare function, while an output can be

switched based on local evaluations in the terminal, e.g., depending on

the measured value of the resistance bridge.

• integrated, switchable 5 V/10 V bridge supply UExc, generated from

the power contacts

The analog EL3356-0090 input terminal enables direct connection

of a resistor bridge or load cell in a 4- or 6-wire connection technology.

The ratio between the bridge voltage UD and the supply voltage UREF

is determined simultaneously in the input circuit and the final load value

is calculated as a process value on the basis of the settings in the terminal.

With automatic self-calibration (can be deactivated) and dynamic filters

the terminal with measuring cycles of 10 ms can be used for slow weighings

with high precision.

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.
