Inputs/outputs

Observe the following information:

  • The digital inputs and outputs are referenced to GND. GND is connected to PE. Incorrectly applied voltages can damage the digital inputs and digital outputs. Do not apply external voltage to the digital outputs.
  • Cables outside the control cabinet must be shielded.
  • When connecting the shielding, ensure equipotential bonding.
  • The cable length must not exceed 30 m.
  • Connect the digital inputs and outputs to the appropriate connections.
