Easy to Use. Controllers are also easy to configure.

Simply connect the SX to the DeltaV network and auto-sense

it from DeltaV Explorer. Add the controller and all its IO cards

to the system database and all components are automatically

addressed and communicating.

„ Control strategies are developed using IEC-61131

programming techniques: Function Blocks,

Sequential Function Charts and Structured Text.

„ Automatic diagnostics and event reporting with

time stamps applied in the controller.

„ Set control execution to match process dynamics

and controller scheduling adjusts automatically.

„ Reference any parameter by its module name,

regardless of its location in the system.

„ Synchronized system clock for consistent time

based event driven actions across the system.

„ Online expandable IO carriers allow new cards to be added

online, with autosense capability, for modular system growth

„ Hardware redundancy is automatically detected with zero

configuration effort.

Benefits

Scalable controllers. The SX controller complements the

SQ controller by providing additional CPU and Memory

for those applications that need more control capacity:

„ Late Changes. You can easily upgrade an SD Plus or

SQ controller to an SX to handle project scope changes

late in the project. Simply replace the SD Plus or SQ with

the SX and all existing configuration, documentation and

hardware design remain the same — forgiving.

„ Speed. The SX controller supports all the features you’ve

come to expect from the DeltaV system: self-addressing,

automatic I/O detection. All these features are designed

to make your projects execute faster — just plug and play!

„ Redundant Architecture. The SX controller supports

1:1 redundancy for increased availability. Redundant SD

Plus or SQ controllers can be upgraded to SX controllers

online — robust!

Quick Assembly. The S-series hardware has been designed for

speed of project execution. Carriers snap to standard DIN rails

and controllers and S-series IO snap into position without the

use of retaining screws.

Field Proven Architecture. The SX controller is an evolution

of the DeltaV MX controller. The new design delivers

installation and robustness enhancement while still using

the same processor and OS that has proven itself in the

field. All IO cards run the latest software enhancements

of corresponding M-series IO cards and deliver the same

field proven, reliable operation.

Designed for Electronic Marshalling. The SX controller

have highly distributable IO capabilities with CHARMs based

Electronic Marshalling. Electronic Marshalling IO can be

mounted anywhere, facilitating system design and expansion

while reducing overall system footprint over traditional

marshalled IO Subsystems.

Advanced Controls. The SX controller supports all the

advanced control features that are expected in a world

class Distributed Control System:

„ Batch Software

„ Model Predictive Control

„ Neural Networks

I/O Cards

A variety of analog and discrete I/O interfaces are available to

meet your specific requirements. The following cards support

simplex or redundant installation:

• AI 4-20 mA HART, eight channels

• AO 4-20 mA HART, eight channels

• DI Dry Contact, eight channels

• DO 24V DC High Side, 8channels

• AI (Plus) 4-20 mA HART, 16channels

• AO (Plus) 4-20 mA HART, 16channels

• DI (Plus) 24V DC, Dry Contact, 32channels

• DO (Plus) 24V DC, High-Side, 32channels

The following I/O cards are supported in simplex format to

meet your field wiring needs.

• AI Isolated, four channels

• RTD, eight channels

• Thermocouple, eight channels

• Millivolt, eight channels

• DI 24V DC Isolated, eight channels

• Pulse Count Input, four channels (Isolated DI)

• Sequence of Event, 16 channels (DI 24V DC)

• DI 120V AC Low Side Detection, eight channels

• DI 120V AC Isolated, eight channels

• DO 24V DC Isolated, eight channels

Pulse Counters are available on most DI cards. The supported

maximum frequency varies from 0.1 Hz on AC signals to 75 or

120 Hz on 24V DC inputs, and up to 50 KHz on the High-speed Pulse input card.

1:1 Redundancy for traditional I/O cards: Increased

system availability is easy with S-series traditional I/O cards.

Four traditional I/O card types are available with redundant

terminal blocks for critical field circuits. Simply install a pair

of cards on the prescribed redundant terminal block and the

DeltaV Distributed Control System (DCS) will automatically

recognize them as a redundant pair. There is no configuration

other than to autosense the redundant pair.

Plug-and-play I/O: All S-series traditional I/O components

plug into the I/O interface carrier and are auto sensed by

the controller. There are no addressing switches or jumpers.

Cards can be installed in any order simplifying the I/O

subsystem design. New I/O interfaces are detected by the

system and added to the engineering database automatically.

Additional features can be enabled as needed and downloaded

without disruption to existing I/O communication,

allowing you to install the I/O you need today with the ability to expand tomorrow.

Easy online expansion: The S-series I/O carriers and interfaces

can easily be added online, without disruption of existing

I/O communication. I/O carriers can be extended online,

either by directly connecting them to the right side of the

existing carrier, or using extender cables to mount the new

carrier on a different DIN rail. The controller automatically

detects new carriers and interfaces and allows these to be

auto-sensed into the configuration database.

Field-mounted capable hardware: All S-series traditional I/O

interfaces are rated for extreme operating temperature ranges

of -40 to 70°C (-40 to 158°F). The interfaces can be installed

in field mounted enclosures so you significantly reduce the

footprint of your equipment and increase valuable control room

space for other uses. This also allows you to save on wiring

expenses by eliminating the need for long runs of multi-cores.

The integrated design of the I/O subsystem can eliminate the

need for marshaling panels. This saves you even more in your

total capital costs.

Reduced installation time and expense: The DeltaV system’s

S-series I/O interfaces are designed for quick assembly and

error proof maintenance. All carriers snap onto T-DIN rails and

interfaces snap into the I/O slots without the use of any tools.

Each I/O interface has a separate wiring terminal block,

which connects field wiring to the interface. The I/O card can

easily be removed without touching the I/O wiring on the

terminal block. Some I/O cards can also use the fused terminal

block, which is equipped with in-line fuses that can be pulled

to isolate power to the field circuit.

Traditional I/O interfaces have I/O function keys that allow

the terminal block to be set to receive a specific I/O card.

These keys ensure that the correct I/O card is always plugged

into the corresponding terminal block. The keys provide a

safety measure by preventing the wrong I/O card being

installed. It’s incredibly easy to use and gives you time to do more.

The I/O carriers provide integrated bussed field power

distribution to the I/O interfaces.

Benefits

Modular and flexible construction: The S-series traditional

I/O subsystem is designed with your investment in mind.

Each controller supports up to eight I/O carriers that form a

robust, passive bus for up to 64 I/O interfaces. Each interface

has a matching I/O terminal block and can be installed in any

I/O slot on the bus. Carriers and interfaces can be added online,

without interruption to the existing I/O communication.

This modular design enables you to purchase the exact

amount of I/O cards, eight-wide carriers, power/controllers,

and two-wide carriers you need and add more DeltaV I/O

as your system grows.

The integrated bus is divided

into primary and secondary power for odd- and even-numbered

slots. Each slot is individually fused to protect power to other

cards. This significantly reduces the external power distribution

circuits while still providing each card with fused 24V DC bussed

field power.
