Description for BECKHOFF KL1488 Channel Digital Input Terminal
The digital input terminal KL1488 (ground switching) acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains eight channels which indicate their signal state by means of light emitting diodes. The KL1488 is particularly suitable for space-saving use in control cabinets. By using the single-ended connection technique, a multi-channel sensor can be connected in the smallest space with a minimum amount of wiring. The power contacts are looped through. For the KL1488, the reference point for all inputs is the 24 V power contact.Technical dataKL1488, KS1488Connection technology1-wireSpecificationground switchingNumber of inputs8Nominal voltage24 V DC (-15 %/+20 %)“0” signal voltage18…30 V“1” signal voltage0…7 V“0” signal current–“1” signal currenttyp. 3 mAInput filtertyp. 3.0 msCurrent consumption K-bustyp. 5 mACurrent consumption power contactstyp. 2 mA + loadElectrical isolation500 V (K-bus/field potential)Bit width in the process image8 inputsConfigurationno address or configuration settingWeightapprox. 55 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, ATEXEx markingII 3 G Ex nA IIC T4 Gc
