pATLAS Mechanical Specification


The implemented mechanical standard for pATLAS modules was developed in accordance with Phoenix Contact COMBICON standards for modular plastic enclosures/housings (COMBICOM ME/TBUS series), which provide:

  • Small size module design;
  • Robust and compact assembling;
  • Easy implementation and installation. 

  • The choice of appropriate enclosures/housing was a starting point in specifying other mechanical parts: PCB, connectors, rails and cabinets, as well as introducing basic requirements and recommendations in designing individual modules.


    • Module Enclosures/Housing

    pATLAS Enclosures

    The selected modular electronic enclosures/housings are available in multiple widths and connection options, and allow a choice of permanent and plug-in connection systems.  Also, they might contain an integrated cross connector that makes it possible to inter-connect housings with each other (stackable enclosures) without blocking other existing connectors.

    pModule PCB Specs

    The implemented standard for pATLAS modules is the small-sized shaped printed circuit board (PCB) that fits into modular plastic enclosure.  This PCB/enclosure match-up enables an easy module handling, as presented here:

    • Connectors


    All modules internal and external connections are provided via appropriate connectors, carefully selected to fulfil the basic requirements regarding an easy and reliable implementation under different environmental conditions.  A special attention was paid to the external connections, primarily how to connect pATLAS I/O modules with the process itself.  The front-side screw-terminals were selected for this purpose – they allow easy access and cable tying in real-life implementations.



    • Cabinets

    Small module sizes and low power consumptions (consequently, low heat emissions) allow a flexible and versatile cabinet choice.  A wide range of available cabinets includes different type and size metal, aluminium, fiberglass and plastic cabinets.  They could be standalone, wall mounted, desk type, or even suitcase like.  The final choice depends on the actual system implementation and environmental requirements and existing site conditions. 



    A common process interface scenario supposes pATLAS housing in the appropriate cabinets, which are usually equipped with separate terminal strips for direct connection with processes.  For interconnection between module’s screw-terminals and cabinet’s terminal strips, the flexible signal cables are used.  They are led through existing cable ducts suitable for easy testing and maintenance.  As an illustration a portion of pATLAS equipment mounted in a metal standalone cabinet in a 110/35 kV transformer station is presented here:

    Terminal strips are located in the accordance with the actual introduction of the process interface cables, usually between cable inlets and pATLAS TBUS rail and modules.  Generally, process signals cabling is not particularly challenging job due to the inherent small capacities of individual pATLAS units.
