The EL3751 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 integrated supply and the switchable auxiliary resistors enable direct

connection of a resistor bridge (strain gauge) or a load cell, a fixed ohmic

resistor, a PTC or a potentiometer.

The signal state of the EtherCAT Terminal is indicated by light emitting

diodes.

Each terminal has a unique ID number.

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

certificate.
