Description for BECKHOFF KL1804 HD Bus Terminal, 4-Channel Digital Input
The KL1804 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 four channels, consisting of a signal input, 24 V DC and 0 V. The signal states are displayed by LEDs. The power contacts are looped through. The reference ground for all inputs is the 0 V power contact. The wires 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 dataKL1804Connection technology3-wireSpecificationEN 61131-2, type 1/3Number of inputs4Nominal voltage24 V DC (-15 %/+20 %)“0“ signal voltage-3…+5 V (EN 61131-2, type 1/3)“1“ signal voltage11…30 V (EN 61131-2, type 3)Input filtertyp. 3.0 msInput currenttyp. 3 mA (EN 61131-2, type 3)Current consumption K-bustyp. 10 mACurrent consumption power contactstyp. 1 mA + loadElectrical isolation500 V (K-bus/field potential)Bit width in the process image4 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. 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/variable (see documentation)ApprovalsCE, UL, Ex, GL
