The KL1212 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The KL1212 generates a short-circuit protected 24 V DC supply voltage for sensors. The sensor outputs can be switched on or off by the controller. A short-circuit or an open lead in the sensor supply is detected, and the terminal status is relayed to the controller via the K-bus. The Bus Terminal contains two channels that indicate their signal state and errors by means of LEDs.
