The ED3361 analog input terminal enables the direct connection of

a resistance bridge (strain gauge – SG) or a load cell 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.

The terminal also has a digital input and a digital output. The digital

input can be used, for example, to trigger a tare function. The digital

output can be switched on the basis of local evaluations in the terminal,

for example depending on the measured value of

the resistance bridge.

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

• additional digital inputs and outputs for local trigger conditions

The ED series EtherCAT Terminals have push-in connection technology

which makes wiring easy and tool-free.

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.

The EL3314-0092 analog input terminal facilitates the direct

connection of four thermocouples in a 2-wire configuration.

The channels are electrically isolated from each other and

from the E-bus, which effectively prevents adverse effects

and damage due to cross currents.

Various types of thermocouples are supported, and voltage

-to-temperature conversions take place within the terminal.

The terminal also allows for mV measurements.

Wire breaks are signaled by error-LEDs, as well as on the

fieldbus. Cold junction compensation is carried out by an

internal precise temperature measurement at the connection

terminals; however,operation with an external cold junction

is also possible.

The EL3314-0092 also supports TwinSAFE SC (TwinSAFE

Single Channel). This enables the use of standard signals

for safety tasks in any networks or fieldbuses.

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.

The ED3274 analog input terminal enables the measurement of

temperatures with resistance thermometers (RTD) or thermocouples

(TC) on four channels. Each channel can be configured individually,

allowing for mixed operation of RTD and TC.

The measured values can be output as resistance or voltage values

or converted directly into a temperature. All common sensor types

are supported.

For temperature measurement with resistance thermometers, sensors

in a 2. 3. or 4-wire system can be connected. A cold junction

compensation is integrated in the terminal for temperature

measurement with thermocouples. This internal measurement can

be switched off so that an external cold junction can be used.
