Description for BECKHOFF EL3204-0200 4-Channel Universal Input Terminal

The analog EL3204-0200 input terminal enables direct connection of four resistance sensors up to 240 kΩ, so that the usable measuring range is significantly larger compared with the EL3204. The EtherCAT Terminal circuit can operate sensors using the 2-wire technique. The resistance values are converted (linearisation) in the terminal either based on preset characteristic curves, conversion formulas with specific material parameters (e.g. according to IEC 60751, Steinhart-Hart equation, B-parameter equation), or a freely programmable conversion table. Sensor malfunctions such as broken wires are indicated by error LEDs.Technical dataEL3204-0200Number of inputs4Power supplyvia the E-busTechnologyTemperature measurement (RTD)Signal typedifferentialDistributed clocks–Sensor typesNi/PT, any RTD in the range of 100 Ω…240 kΩ, calculation possible on the basis of a table or material constant, resistance measurementConnection method2-wireConversion timeapprox. 24 ms default setting, 4…500 ms configurableMeasuring currenttyp. < 0.03 mAResolution0.1 °C per digitMeasuring error< ±0.3 % relative to full scale value (6 kΩ, 65 kΩ, 240 kΩ)Electrical isolation500 V (E-bus/signal voltage)Current consumption power contacts–Current consumption E-bustyp. 150 mABit width in the process image4 x 32 bit RTD inputSpecial featurestemperature calculation on the basis of Steinhart-Hart, B parameters, IEC 60751, free table, predefined sensorsWeightapprox. 60 gOperating/storage temperature0…+55 °C/-25…+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, ATEXEx markingII 3 G Ex nA IIC T4 Gc
