Beckhoff EL3681 | EtherCAT Terminal, 1-channel analog input, multimeter

The EL3681 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 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.

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

certificate. (See related products)
