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, which reduces project schedules.
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 unique ‘field disconnect’ mode for added protection and flexibility. 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.
The redundant Ethernet FCI of Select I/O makes this solution even more flexible and useful for all projects. 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.
“With this extension of the ABB AbilityTM System 800xA offering our customers get many new cost saving opportunities for their automation projects. The flexibility that Select I/O brings with it will certainly change the way of executing projects.” says Ilpo Ruohonen, BU Managing Director Control Technologies.
ABB AbilityTM System 800xA and its extended automation concept has over 10,000 installations world-wide, in practically every industry, automating processes, controlling and monitoring electrical equipment, and reducing risk through high integrity safety systems. Now, through its integration capabilities and flexible I/O solutions, it’s taking the drama out of automation projects and removing them from the critical path.
