Description for BECKHOFF EL3044 4-Channel Analog Input Terminal
The EL3044 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits and is transmitted (electrically isolated) to the higher-level automation device. The EL3044 EtherCAT Terminal features 2-wire conductors for the four single-ended inputs with a common internal ground potential. The power contacts are connected through. The signal state of the EtherCAT Terminal is indicated by light emitting diodes.Technical dataEL3044 | ES3044Number of inputs4 (single-ended)Power supplyvia the E-busTechnologysingle-endedSignal current0…20 mADistributed clocks–Internal resistancetyp. 85 ΩInput filter limit frequency1 kHzDielectric strengthmax. 30 VConversion time0.625 ms default setting, configurable, multiplexResolution12 bit (16 bit presentation incl. sign)Measuring error< ±0.3 % (relative to full scale value)Electrical isolation500 V (E-bus/signal voltage)Current consumption power contacts–Current consumption E-bustyp. 130 mABit width in the process imageinputs: 16 byteConfigurationno address or configuration setting requiredSpecial featuresstandard and compact process image, activatable FIR/IIR filters, limit value monitoringWeightapprox. 60 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/variablePluggable wiringfor all ESxxxx terminalsApprovals/markingsCE, UL, ATEX, IECExEx-MarkingII 3 G Ex nA IIC T4 GcEx nA IIC T4 GcEx tc IIIC T135 °C Dc
