ABB has launched an addition to its automation platform ABB Ability System 800xA; a redundant Ethernet based single channel I/O system called Select I/O. Select I/O supports ABB’s project execution model called Intelligent Projects that provides efficiency improvement for automation projects. Select I/O allows users to install standardized cabinets with the bases for field wiring early during a project, then select the type of I/O much later. It digitally marshals signals instead of using space and labor intensive marshalling panels and allows loop checks to be done before the rest of the system is delivered. This minimizes the impact of late changes and allows for project tasks to be done in parallel. The Select I/O solution’s network is connected via an Ethernet Fieldbus Communication Interface (FCI) with embedded redundant switches and uses individual Signal Conditioning Modules (SCMs) for process and safety I/O. In addition to being field ready with temperature ratings of -40 to 70 degrees Celsius and having galvanic isolation per channel, each SCM is current limited and has a ‘field disconnect’ mode for added protection. Line monitoring DIs, SOE and high current options are also available to reduce the need for ancillary third party equipment which aids in I/O cabinet standardization. In addition to being used for Select I/O, the FCI can accept System 800xAs’ multi-channel S800 I/O allowing the user to select the I/O solution that best fits the application.
