Description for BECKHOFF KL1889 HD Bus Terminal, 16-Channel Digital Input
The KL1889 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 device. The Bus Terminal contains 16 channels, whose signal states are displayed by LEDs. The terminal is particularly suitable for space-saving use in control cabinets. By using the single-conductor 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.The KL1889 Bus Terminal takes the 24 V power contact as its reference for all inputs. The conductors can be connected without tools in the case of solid wires using a direct plug-in technique.The HD Bus Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.Technical data Connection technology1-wireSpecificationground switchingNumber of inputs16Nominal voltage24 V DC (-15 %/+20 %)“0” signal voltage18…30 V“1” signal voltage0…7 VInput filtertyp. 3.0 msInput currenttyp. 3.0 mACurrent consumption K-bustyp. 20 mACurrent consumption power contactstyp. 4 mA + loadElectrical isolation500 V (K-bus/field potential)Bit width in the process image16 inputsConfigurationno address or configuration settingConductor typessolid wire, stranded wire and ferruleConductor connectionsolid wire conductors: direct plug-in technique; stranded wire conductors and ferrules: spring actuation by screwdriverRated cross-sectionsolid wire: 0.08…1.5 mm²; stranded wire: 0.25…1.5 mm²; ferrule: 0.14…0.75 mm²Weightapprox. 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/variable (see documentation)Approvals/markingsCE, UL, ATEX, GLEx markingII 3 G Ex nA IIC T4 Gc
