Description

The KL2808 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation. The KL2808 is protected against polarity reversal and processes load currents with outputs protected against overload and short-circuit. The Bus Terminal contains eight channels, consisting of a signal output and 0 V DC. The signal states are displayed by LEDs. The power contacts are looped through.
