D-sub sockets, 25-pin
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.
