| About product | 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 parameterised, 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. To suppress aliasing effects, the input channel features two configurable numeric software filters up to 39th order FIR/6th order IIR. The filters can be preselected or freely described, so that a band stop or a band pass can be realised. The measurement at the differential input channel is digitised with a resolution of 24 bit and 10 ksps and is transmitted to the higher-level automation device electrically isolated and optionally with oversampling. The data rate can be internally reduced, in which case the filters have to be adjusted accordingly. Non-linear characteristic sensor curves can be corrected flexibly through an integrated sampling points table. Simple mathematical operations are also possible. 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.
