The EL3681-0030 EtherCAT Terminal enables measurement of currents

and voltages in a wide input range. The measuring ranges are switched

automatically, as usual in advanced digital multimeters.

For current measurements, two current paths are available, one of which

is a high-current path for up to 10 A. The current and the voltage

measurement facility can be used for DC and AC.

The alternating parameters are output as true RMS values. 

The measurement readings can be read and processed with EtherCAT.

At the same time, the EL3681-0030 enables the measuring type and range

to be set via the bus.Excellent interference immunity is achieved through

the fully electrically isolated design of the electronic measuring system and

the dual-slope conversion system. High precision and simple, high-impedance

measurement from 300 mV to 300 V allow the EtherCAT Terminal to be used

like a modern digital multimeter.

In measuring applications in particular, the voltage to be expected is often

not yet known during the planning phase. Automatic adjustment of the

measurement range simplifies use and reduces stock levels.

The selected measuring type and overload are indicated by LEDs.

For the EL3681-0030. an individual calibration certificate is available, currently

as a choice of DAkkS or IS0 17025-compliant certificate. The certificate is issued

by an accredited service provider in collaboration with Beckhoff.

The individual calibration certificate for each device, in accordance with ISO

17025 or DAkkS, depending on the device variant, can be downloaded here.

These calibration certificates are issued for Beckhoff by an accredited service

provider. Recalibration on request.
