Notice

Incorrect signal levels due to electromagnetic interference

Digital inputs with a 10 µs input filter are optimized for fast signal transmission and are therefore susceptible to electromagnetic interference.

Under the influence of electromagnetic interference, a false signal level can be detected.

  • If necessary, use shielded signal lines.
