ABBAdvant® 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 signaloriented 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

On-board processing capabilities

The process I/O modules are “intelligent” in the sense 

that module-related signal and data processing is 

performed on board as opposed to centrally, by the 

CPU of the host controller. Time tagging of events, 

filtering and gain control are some examples of 

board-level tasks. This functional distribution improves 

real-time performance and reliability of the system 

as a whole and maintains processing capacity when 

the system is expanded.

Comprehensive self-diagnostics

Comprehensive self-diagnostics continuously monitor 

the modules and report any errors through LEDs on 

the module fronts and through alarm messages and 

indications to process operator stations. 

Malfunctioning inputs can be disabled and simulated 

by manual entry while failing outputs are deactivated 

or driven to a predetermined safe state automatically. 

All I/O modules can be replaced while the system is in 

service. Some modules can even be arranged, transparently into dually redundant configurations 

forenhanced availability.

High disturbance immunity

All modules conform to the highest standards of 

electromagnetic noise immunity and satisfy the 

requirements of the EU directives 2014/30/EU and 

2014/35/EU. For the above reasons, S100 I/O is likely 

to be the best help you can get for putting your control system in touch with your field devices.
