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, trans parently 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 con trol system in touch with your field devices.
