2-Channel 24 V DC
Digital Input Terminal
The KL1212 digital input terminal acquires the binary control signals from the process
level and transports them as electrically isolated signals to the higher-level control
system. The KL1212 variant creates a 24 V DC short-circuit proof supply voltage for
sensors. The sensor outputs can be switched on and off by the control system. A
short-circuit or wire break in the sensor supply is recognized and the terminal status is
passed on to the control system via the K-Bus. The bus terminal contains two channels,
which indicate their signal status and errors with LEDS.
The KL1202 is further available.
