Description for BECKHOFF EL3042 2-Channel Analog Input Terminal

The job of the EL3042 analog input terminal is to supply power to measuring transducers located in the field, and to transmit analog measurement signals with electrical isolation to the automation device. The voltage for the sensors is supplied to the terminals via the power contacts. The power contacts can optionally be supplied with operating voltage in the standard way or via a supply terminal (EL9xxx) with electrical isolation. The input electronics is independent of the supply voltage of the power contacts. The 0 V power contact is the reference potential for the inputs. The EtherCAT Terminal indicates its signal state by means of light emitting diodes.Technical dataEL3042, ES3042Number of inputs2 (single-ended)Power supplyvia the E-busTechnologysingle-endedSignal typesingle-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: 8 byteSpecial 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, ATEXEx markingII 3 G Ex nA IIC T4 Gc
