SIEMENS S7-300 Ex analog output modules Technical specifications

Ex analog output modulesEx analog output modules

  • Analog outputs for signals from the Ex field
  • For the connection of intrinsically safe analog equipment from the Ex field
  • 4 analog outputs in 4 channel modules (single-channel isolation)
  • Diagnostics and diagnostics alarm programmable

The Ex analog output modules have the following mechanical features:

  • Compact configuration;
    the rugged plastic housing contains:

    • A shared 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 cable guide to cover the module’s 24 V load power 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.
