Description

The ABB DSDX453, order number 5716075-AN, is a digital I/O expansion unit in the S400 Remote I/O system for ABB Advant Master distributed control systems (DCS). It provides additional digital input and relay output channels through connection to a compatible basic unit. Its documented configuration includes 20 digital inputs for 48 V DC signals and 12 digital relay outputs, making the distinction between input signal voltage and output type important when selecting the module for an existing installation.

The DSDX453 communicates only with the basic unit to which it is connected and is monitored by that unit. It is listed as an expansion option for the DSDX454 and DSDI454 basic units. Status indicators cover operation, channel status, power supply, and transducer power supply. The expansion unit is not designed to operate as an independent fieldbus-connected basic unit.

Introduction

General

This document, “ABB Advant Energy Management Systems Type Circuits & Functions” for Master software, contains a brief description of all functions of the ABB Advant Energy Management Systems.

Advant EMS provides economical control and supervision of the power-generation and -supply in industrial plants. The main reason for considering the Advant EMS is very often the need for Load Shedding. This system drastically increases the overall plant safety by assuring electrical power and steam for critical loads and avoids blackouts.

The costs, caused by production losses, of a complete blackout easily can go up to one million USD per blackout. With the provided tools it is possible to ensure safe operations with less personnel. Better, faster and more comprehensive information from the process is thus a necessity. For many (petro-)chemical, steel and cement industries the costs for energy form at least 30-50 % of the production costs. The Advant EMS increases the efficiency and the pay back time of the system is very short (<less than 2 years).

Advant EMS allows for more critical designs of the electrical equipment in a plant. The Advant EMS will re-arrange generation, importation and loading in such a way that the individual generators, reactors, transformers, and tie-lines are operated well within their specifications. The integration and serial communication with Motor Control Centres, Protection Units, Governor controllers, Variable Speed Drives and other subsystems give high savings in copper wiring and maintenance costs. The optical connections provide a rigid network that does not suffer from electromagnetic interference.

Since 1986 ABB Systemen BV in Rotterdam, the Netherlands has been actively working in the field of Industrial Electrical Energy Management Systems (Advant EMS).

Realising projects all around the world, the power automation group has built up specific application know how regarding the control and monitoring of electricity networks for industrial process plants. The Advant EMS functionality has gained wide acceptance among its users.

Since January 1996 ABB Systemen BV is the product responsible unit (PRU) for the applications for this type of energy management systems within the business unit COG of ABB IAD.

A wide range of products is available to allow for a cost-efficient and reliable engineering of the EMS systems. The well tested and documented products (software type circuits and system software modules) guarantee a significantly decreased project execution time and (even more important) shorter commissioning periods.

In case, projects are run by the local ABB Automation companies or Regional Centres, ABB Automation Benelux can support these projects either by supporting man-hours or by providing tools like project quality control plans, frames for functional design specifications and pre-defined project time schedules. These tools help in order to achieve a smooth and optimised project execution.
