Brad® Direct-Link® Industrial Ethernet switch with corrosion-resistant housing. Industrial-control applications require complex networks with high data-rates and time sensitive devices whilst harsh environments on the plant floor create vibration, heat and other hazards. Direct-Link® Ethernet switches meet the 3 main challenges posed by industrial Ethernet applications determinism, robustness and integration. Determinism is the assurance that control communication will occur in a set period of time. Delivery of information in the prescribed time requires the use of industrialized protocols Ethernet/IP, PROFINET or Modbus TCP. Unmanaged, standard duty (SD) switches in tough, Lexan plastic enclosures provide a cost-effective network solution for a multitude of low-end applications. Heavy-duty (HD) aluminium enclosures with wide temperature operation are the solution for tougher industrial applications. Easy configuration of managed switches with advanced flexibility and diagnostics provides a superior user experience.
