The KL1184 digital input terminal acquires the binary 24 V DC control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The Bus Terminal contains four channels that indicate its signal state by means of light emitting diodes.
The KL2184 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation.
The KL9184 potential distribution terminal provides the potential of the 24 V DC contact at 8 terminal points and the potential of the 0 V contact at 8 terminal points. The conductors can be connected without tools in the case of solid wires using a direct plug-in technique.
