Description for BECKHOFF EL3174-0002 4-Channel Analog Input

The EL3174-0002 analog input terminal has four individually parameterisable inputs. Signals in the range from -10/0 to +10 V or -20/0/+4 to +20 mA can be processed via each channel. Each channel should be set by the controller to U or I mode via CoE. The input voltage or current is digitised with a resolution of 16 bits, and is transmitted, electrically isolated, to the higher-level automation device. With a technical measuring range of ±107 % of the nominal range, the terminal also supports commissioning with sensor values in the limit range and diagnostics according to NAMUR NE43. The four differential inputs are electrically isolated against each other and against the fieldbus (2,500 V DC).Technical dataEL3174-0002Number of inputs4Power supplyvia the E-busTechnologydifferential input, channels electrically isolatedOversampling factor–Distributed clocksyesDistributed clock precision<< 1 µsInternal resistance> 200 kΩ | typ. 85 ΩInput filter limit frequency5 kHzConversion timeminimum 150 µsMeasuring range, nominal-10/0…+10 V | -20/0/+4…+20 mAMeasuring range, technical-10.73…+10.73 V | -21.47…+21.47 mAResolution16 bit (incl. sign)Measuring error< ±0.2 % (at 25 °C ±5 °C, or else < ±0.3 %, relative to full scale value)Electrical isolation2500 V functional isolation (test voltage channel/channel and channel/fieldbus, production test)Current consumption power contacts–Current consumption E-bustyp. 150 mABit width in the process imageinputs: 16 byteConfigurationno address or configuration settingSpecial featuresU/I parameterisable, Extended Range, standard and compact process image, activatable FIR/IIR filtersWeightapprox. 65 gOperating/storage temperature-25…+60 °C/-40…+85 °CRelative humidity95 %, no condensationVibration/shock resistanceconforms to EN 60068-2-6/EN 60068-2-27EMC immunity/emissionconforms to EN 61000-6-2/EN 61000-6-4Protect. class/installation pos.IP 20/variableApprovals/markingsCE, UL
