Дизайн



Digital output modules are characterized by the following mechanical features:

  • Compact configuration:
    The rugged plastic housing contains:
    • Green LEDs for indicating the signal statuses at the outputs
    • One red LED each to indicate internal and external faults or errors, and to display blown fuses and the absence of the load voltage
    • Labeling strips
  • Simple assembly
  • User-friendly wiring:
    The modules are wired by means of a plug-in front connector.

Функции



Digital output modules convert the internal signal levels of the S7-400 in the external signal levels required for the process.
