ELM7211 and ELM7221

WARNING

Safety functions require connection cables from Beckhoff

The safety certification of product variants -9016 and -9018 requires the use of connection cables from Beckhoff.

  • Only use connection cables from Beckhoff for safety applications.

Notice

Incorrect signal levels due to electromagnetic interference

The digital inputs 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.
