  Информационные материалы

  The following SIPLUS S7-400 F digital modules are available for use in extreme environmental conditions:

  • SIPLUS S7-400 SM 421;
    digital inputs
  • SIPLUS S7-400 SM 422;
    digital outputs

  SIPLUS S7-400 digital modules are designed for use in the following environmental conditions:

  • Extended ambient temperature range from -25 °C to +60 °C
  • Where increased resistance to chemical, mechanical and biological loading as well as salt spray is required
  • Higher installation altitudes
  • In relative humidity up to 100%

  Область применения

  Digital input/output modules are used to interface binary process signals to the S7-400. Digital sensors and actuators can be connected to the SIMATIC S7-400 via these modules.

  Use of the digital input/output modules offers users the following advantages:

  • Optimal adaptation:
    The number of inputs/outputs can be adapted to the corresponding task with the help of modules which can be combined as required. Superfluous investments are avoided.
  • Flexible process connection:
    The S7-400 can be connected to the process via many different digital actuators and sensors.

  Дизайн

  Digital output modules feature the following mechanical characteristics:

  Compact design

  The rugged plastic housing contains:

  • Green LEDs for indicating the signal status at the outputs.
  • Two red LEDs for displaying internal/external errors, with modules with diagnostics capability, and for display of faults (e.g. blown fuses and absence of load voltage).
  • Labeling strips for sliding into the front connector (included in scope of delivery; also as copy template in manual); cover foils can be obtained as option.

  Easy installation

  The modules are hung into the subrack and screwed in place.

  User-friendly wiring

  The modules are wired via a plug-in front connector. When the module is connected for the first time, a coding latches in the front connector so that this now only fits onto modules with the same voltage range.

  When a module is replaced, the front connector can be used for the new module of the same type with the complete wiring.
