BECKHOFF KL1212 Bus Terminal
The KL1212 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 two channels whose signal states or errors are indicated by LEDs. The KL1212 generates a short-circuit proof 24 V DC supply voltage for sensors. A short circuit or a wire breakage in the sensor supply is detected, and the terminal status is relayed to the controller via the K-bus.
