Beckhoff EL3446-0011 | EtherCAT Terminal, 6-channel analog input, current

The EL3446-0011 EtherCAT Terminal enables measurement of

all relevant electrical data in the supply grid and performs simple

pre-evaluations. Since the EL3446-0011 itself has no voltage

inputs, the measured voltage values are transmitted via EtherCAT

from an EL3443 to be installed once per network.

The current in the connectable phases – of which there are up

to six – is fed in via simple current transformers. All measured

currents and voltages are available as RMS values. 

In the EL3446-0011. the active power and the energy consumption

for each phase are calculated. RMS values are available for voltage

U and current I as well as active power P, apparent power S,

reactive power Q, frequency f, phase shift angle cos φ, and

harmonics. The EL3446-0011 offers options for comprehensive

network analysis and energy management.

With 100 mA inputs, the EL3446-0011 is particularly suitable for

evaluating differential current transformers (such as the SCT4xxx)

and DC-capable current transformers.
