The digital KL2798 Bus Terminal provides eight switches that can be used like a relay contact for AC/DC voltages. The electronic switch is realized 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.
