Description for BECKHOFF KL1722 -Channel Digital Input Terminal
The KL1722 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. It is possible to connect 120 V/230 V AC sensors directly. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes. The KL1722 does not have any power contacts. This makes it possible to create individual potential groups. The voltage between input 1 and input 2 must not exceed the max. nominal voltage of 230 V AC.Technical dataKL1722 | KS1722Connection technology2-wireNumber of inputs2Nominal voltage120/230 V AC“0” signal voltage0…40 V“1” signal voltage79…260 VInput filtertyp. 10 msInput current> 3 mA, typ. 6 mACurrent consumption K-bustyp. 3 mASwitching times10 msElectrical isolation500 V (K-bus/mains voltage); 3750 V AC, 1 min.Bit width in the process image2 inputsConfigurationno address or configuration settingSpecial featuresohmic/capacitive input behaviourWeightapprox. 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/variablePluggable wiringfor all KSxxxx Bus TerminalsApprovals/markingsCE, UL, ATEX, GLEx markingII 3 G Ex nA IIC T4 Gc
