The KL2889 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation. The KL2889 is protected against polarity reversal and processes load currents with outputs protected against overload and short-circuit. The Bus Terminal contains 16 channels, whose signal states are displayed by LEDs. The terminal is particularly suitable for space-saving use in control cabinets. The connection technology is particularly suitable for single-ended inputs. All components have to use the same reference point as the KL2889. The power contacts are looped through.
The outputs are fed via the 0 V power contact in the KL2889. The conductors 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.
