Description for BECKHOFF KL2798 HD Bus Terminal
The digital KL2798 Bus Terminal provides eight switches that can be used like a relay contact for AC/DC voltages. The electronic switch is realised through high-performance MOSFET transistors with low switch-on resistance. The switch itself is not short-circuit-proof, but due to its high pulse current capability it can cope with current until an external fuse triggers a switch-off.Wear resistance increases the availability of the application. Resistive and inductive loads can be switched up to a rated voltage of 30 V AC/DC, completely resistive loads also up to a rated voltage of 48 V DC.High peak voltages and electromagnetic interference pulses are prevented.Technical dataKL2798Connection technology2-wireNumber of outputs8 x make contactsRated load voltage0…30 V AC/DC (only ohmic load: 0…48 V DC)Max. output current2 A per channel (∑ 10 A)Breakdown voltage80 VPeak current5 A (100 ms), < 50 A (10 ms)Short circuit currentnot short-circuit-proof, see peak currentReverse voltage protection–Isolation voltage (channel/channel)< 200 VElectrical isolation500 V (K-bus/field potential)Switching on speedtyp. 1.8 ms, max. 5 msSwitching off speedtyp. 30 ms, max. 50 msOn-resistancetyp. 0.03 ΩCurrent consumption power contacts–Current consumption K-bus80 mABit width in the process image8 outputsConductor 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 mm²Special featuressubstitute for relay contacts, potential-freeOperating/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/variableApprovalsCE, ULRelated products
