ABB Ability™ System 800xA

ABB Ability™ System 800xA

ABB’s S400 I/O system has been  around since 1986 and created a  reputation for itself world-wide as  a capable and reliable I/O system.  But these days, spares are getting  ever harder to come by, and the  system does not support the  industry-standard field buses of  today.

Consequently ABB has developed a replacement  solution, based on its current – and future – I/O system  S800, which is designed to provide expanded functionality, greater flexibility, higher reliability,  and improved self-diagnostics.

More specific benefits available when upgrading  from S400 I/O are: 

• Retain existing field wiring, right up to their  plug-in connectors. 

• Unscrew the old unit and put the new one in its  place! It will fit perfectly, down to the existing  screw holes, DIN rail and connectors. 

• Pretested functionality, from the connector  sockets in. 

• Shortest possible downtime. Just plug in and produce! 

• Enables HART® fieldbus support and thereby  management of intelligent field devices from a  central point.

The evolution units consist of platemounted S800  I/O modules with exactly the same footprint and  mounting alternatives (corner screws or DIN rails)  as those of the old S400 units. And of plug connector  sockets and intermediate wiring that match up to the  existing field wiring and its connectors perfectly.

Upgrading to S800 I/O is essentially as easy as removing the existing S400 I/O station and putting  the new I/O assembly in its place.

The reward is a more capable, adaptable and maintenance-friendly I/O system that will provide reliable  service far into the future. Thereby contributing as  much as an I/O system ever can to higher output and  a better financial return.
