Application

The following intrinsically-safe equipment can be connected to Ex digital output modules:

Solenoid valves, indicator lights, LEDs

Function

The Ex digital output modules convert the internal signal level of the PLC into external binary signals for the intrinsically-safe equipment in the Ex field.

Design

The Ex digital output modules have the following mechanical features:

  • Compact configuration;
    The rugged plastic housing contains:

    • Green LEDs for each circuit to indicate “1” signal (internal status, not affected by short-circuit at the terminals)
    • Red LEDs for each circuit to indicate wire break or short-circuit.
    • Slot for front connector and 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.
