The KL2012, KL2022 and KL2032 digital output terminals connect the binary control signals from the
automation unit on to the actuators at the process level with electrical isolation. The KL2012 and KL2022
versions handle different load currents, and their outputs are protected against overload (only KL2012) and
short circuit. The KL2032 Bus Terminal is protected against reverse polarity connection. The Bus Terminals
contain two channels that indicate their signal state by means of light emitting diodes.
