The EL3751-0020 analog input terminal is part of the new generation of

analog EtherCAT measurement terminals. The nominal measuring range

of the input channel can be comprehensively parameterized, both

electrically and on the software side:

• voltage measurement: ±5 mV to ±30 V (incl. ±10 V), 0…10 V, 0…5 V

• current measurement: ±20 mA, 4…20 mA, 0…20 mA, NAMUR NE43

• resistance measurement: 0…5 kΩ

• electrical resistance R in 2-/3-/4-wire connection

• RTD measurement in 2-/3-/4-wire connection

• strain gauge/load cell: ¼ bridge (350 Ω + 120 Ω), ½ bridge (±16 mV/V)

and full bridge (±32 mV/V) with integrated supply in 2-/3-/4-/5-/6-wire

connection

• potentiometer: min. 1 kΩ

The measuring ranges generally reach accuracy class 0.01%. For further

information please refer to the documentation. Through the feature

“ExtendedRange” the user has the full technical measuring range available,

up to 107% of the specified nominal measuring range, depending on the

measuring range. This feature can be disabled, in order to ensure compatibility

with the “LegacyRange” of the EL30xx/EL31xx series.
