ABB Ability™ System 800xA Advant® Master S400 I/O to S800 I/O Evolution

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.

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.
