Select I/O

Universal I/O - modular, single point, late binding, Ethernet I/O solution able to be digitally marshalled into the ABB Ability System 800xA architecture

Select I/O is a Ethernet based single channel I/O solution for  ABB Ability™ System 800xA that offers full redundancy down to the Signal Conditioning Module. Each signal coming from the field is conditioned individually with a Signal Conditioning Module (SCM) for both process and safety applications.

The Select I/O together with the innovative xStream Engineering tools helps decouple project tasks, minimize the impact of late changes and supports standardization of hardware and cabinets helping projects come on time and under budget.  A robust field friendly design provides features such as:

  • Hardware selectable I/O types
  • Field disconnect mode (connected to system, but isolated from the field)
  • Keyed terminal blocks
  • Electronic current limitation and galvanically isolated (per channel)
  • Line monitoring for all I/O types
  • Extended temperature ranges -40°C to +70°C (-40°F-158°F)
  • Up to 192 SCM’s per Ethernet I/O cluster
  • Zone 2 and Class 1 Division 2
  • SIL3 certified safety modules (DI, DO, AI, AO)
  • Single channel and multi-channel (S800) I/O in the same system / Ethernet I/O network
  • HART variables to the application
  • SOE for Digital Input (1 ms)
  • Support for digital marshalling any channel to any controller

Select I/O is suitable for many types of projects, especially for:

  • Large capital intensive (complex) project with high risk of late changes and schedule delays
  • Projects with small counts of distributed I/O (for example well pads)
  • Retrofit projects
  • Fast track projects with the need for flexibility
