Beckhoff ELM3102-0100 | EtherCAT Terminal, 2-channel analog input, multi-function

The ELM310x EtherCAT Terminals are designed for flexible current

measurement in the range from -20 to +20 mA.

They offer selectable measuring ranges of -20/0/4 to ±20 mA as

well as current measurement according to NAMUR NE43.

The measuring range is selected in the CoE, as are the other setting

options such as the filter parameters. Irrespective of the signal

configuration, all ELM modules have the same technological properties.

The ELM310x modules for current measurement offer a maximum

sampling rate of 10.000 or 20.000 samples per second.

The 2-pin plug (push-in) can be removed for maintenance purposes

without releasing the individual wires.

This terminal is also available as a variant with an individual calibration

certificate. (See related products) Extensive documentation is available

from Beckhoff sales, support or measurement@beckhoff.com.

This ELM3xxx series measurement terminal enables efficient

implementation of complex system-integrated data acquisition systems

(DAQ) that place high demands on measurement accuracy and time

synchronization.

The ELM3002-0325 EtherCAT Terminal in the basic series is designed

for low-voltage measurement in high-voltage systems (AC or DC),

especially current measurement via shunt or single-cell measurement.

It has an adjustable measuring range of ±60 mV to ±5 V per channel

and electrical isolation between the channels.

The measuring range is selected in the CoE, as are the other setting

options such as the filter parameters. Regardless of the signal

configuration, all ELM modules have the same technological properties,

and the ELM3002-0325 with oversampling offers a maximum sampling

rate of 50.000 samples per second and channel.

The terminal is equipped with 4 mm laboratory sockets.

The individual Beckhoff factory calibration certificate can be downloaded

via Beckhoff Service.

The EL3783 EtherCAT Terminal is a power monitoring I/O terminal

 used for state monitoring of a 3-phase AC voltage system.

For each phase, voltage up to 400/690 Vrms and current up to 1

Arms/5 Arms are sampled as instantaneous values with a resolution

of 16 bits. The six channels are measured simultaneously based on

the EtherCAT oversampling principle with a temporal resolution of

up to 50 µs and then passed on to the control system.

With the processing power available there and in combination with

the TwinCAT Function TF3650. true RMS or power calculations as

well as complex user-specific algorithms can be calculated via the

voltage and current characteristics. Through the oversampling

principle, the terminal is able to measure at significantly shorter 

intervals than the cycle time of the control system.

AC and DC parameters must be connected and measured with a

common reference potential.
