The Ex analog input modules have the following mechanical features:

  • Compact configuration;
    The rugged plastic housing contains:

    • A single red group fault LED for all circuits
    • One red LED each per channel for displaying channel-specific faults/errors, e.g., wire break or load break
    • Slot for front connector or cable guide, protected by the front cover
    • Labeling area on the front cover.
  • Easy installation:
    The module is mounted on the DIN rail and connected to the adjacent modules via bus connectors. There are no slot rules; the addresses of the inputs are predetermined by the slot.
  • User-friendly wiring:
    The modules are wired by means of a plug-in front connector. When they are first plugged in, a coding element clicks into place so that the connector will only fit into modules of the same type. The front connector contains a special barrier for covering the module’s 24 V load current supply. When the module is replaced, the front connector can be used in its fully wired state for the new module of the same type.
