ABB Advant® Master S100 I/O system

The S100 I/O process interface modules for Advant Controller 400 series process controllers come with connection units, simplifying cable termination and keeping noise and destructive spikes away from the central electronics

S100 I/O is the central process interface for Advant

Controller 400 series process controllers. Thanks to

built-in cablemarshalling facilities and parallel

communication with the host controller, it is the

right choice for centralized I/O systems and

high-speed applications.

The range of process I/O modules is complete,

consisting of general purpose digital and analog

inputs and outputs and special interfaces for special

tasks. These specials include pulse counting,

frequency measuring, positioning, motor speed

control and communication with other controllers.

All I/O modules provide simple interfacing, accurate -

yet fast - control, and easy integration of individual

loops into a comprehensive plant-wide control

and supervision system.

The interface modules connect to the process

through screw terminals on connection units

normally installed inside, at the back of the cabinet.

This solution keeps noise and destructive voltage

spikes away from the central electronics and

provides a neat and tidy process interface that is

easy to maintain.

Prefabricated cables interconnect modules with

connection units. The cables come in different

lengths, permitting termination and marshalling

in controller cabinets, in adjacent cabinets, or in

cabinets a greater distance away.

There are connection units that support signal

oriented or device-oriented field wiring. The former

means that field wires with the same electrical

characteristics (e.g. all 24 V d.c. inputs) are grouped

and terminated together, the latter that field wires

to/from the same field devices are grouped and

terminated together. The combination means

maximum installation flexibility.
