KL2212 | 2-channel digital output terminal 24 V DC with diagnostics

The KL2212 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation. The load current output of the KL2212 version is protected against overload and short-circuit. A short-circuit or an open lead is detected, and the terminal status is relayed to the controller via the K-bus. The Bus Terminals each contain two channels that indicate their signal state and errors by means of light emitting diodes.
