KL1212 | Bus Terminal, 2-channel digital input, 24 V DC, 3 ms, with diagnostics

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.

 

Special features:

  • input specification type 1
  • no bouncing due to mechanical switches thanks to 3 ms input filter
  • short-circuit proof sensor supply
  • possibility to diagnose open circuit and short circuit

Product status:
