KL1889 | Bus Terminal, 16-channel digital input, 24 V DC, 3 ms, ground switching

The KL1889 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 sixteen channels whose signal states are indicated by light emitting diodes. The power contacts are connected through. With the KL1889, the reference ground for all inputs is the 24 V DC power contact.

 

Special features:

  • ground switching
  • no bouncing due to mechanical switches thanks to 3 ms input filter
  • tool-free connection by direct plug-in technology for solid wire conductors
  • space-saving use in the control cabinet
  • direct connection of multi-channel sensors in 1-wire connection technology in the smallest space
