Power Supplies

The SD83x and SD85x Power Supply Units are designed to meet all the applicable electrical safety

data stated by the EN 50178 harmonized European

Standard Publication and the additional safety and

function data required by EN 61131-2 and UL 508.

The secondary output circuitry is accepted for SELV

or PELV applications.

They are switch-mode Power Supply Units which

convert the mains voltage to 24 volts d.c. These

power supplies can be utilized for non-redundant

and redundant applications. Redundant applications

require diode voting units SS823 or SS832.

With the type SD83x series Power Supply Units,

there is no requirement for the installation of a

mains filter. They provide a soft start feature; power-on of an SD83x will not trip fuses or earth-fault

circuit breakers. The SD822Z is also G3 compliant.

Scales from low cost, standard function to high end features like hot-swap, HART, time tagging, redundancy down to I/O channel.

S800 I/O is an open comprehensive, distributed, process I/O system that communicates with

controllers by direct connection or over industry-standard field buses.

Thanks to its open connectivity it fits a wide range of process controllers from ABB and others.

By permitting installation in the field, close to sensors and actuators, S800 I/O reduces the installation cost by reducing the cost of cabling.

Leading paths to greater awareness, faster response and better decisions

Handling the unplanned outages has become the number-one priority for many companies today. On an average, operators deal with thousands of alarms per day. Hence, they should face no more than two alarms per 10-minute period but alarm overload distracts the operators and often causes unplanned downtime.

For maximum plant performance, high performance HMI and advanced alarm management helps to improve the operator’s tools and work environment. An ABB case study reveals savings of more than $800.000 from upgrading to a high performance HMI.

Importance of HMI

In control rooms of old, the number of alarms was limited by the amount of space on the control room panel board and the cost of wiring equipment from the production area to the board.

Annunciators, indicators and switches (to acknowledge and clear a resolved alarm) had to be essential to justify a place on the panel. If a new alarm was needed, an existing alarm would usually have to  make way.

This began to change with digital signals and the distributed control system (DCS) in the 1980s. Panel boards were replaced by monitors and servers, and signals were transmitted from plant equipment to computer processors, where the signals were turned into actionable information. But the alarms were overloading the control room and terms such as flooding, nuisance, chattering, fleeting and stale were coined to describe them and their effect on the operators.

ASTAT® for industry!

ASTAT, with slip-ring motors, has become the

leading technology for new heavy industrial

cranes in the growth regions of the world.

In Europe, ASTAT is mostly used for retrofit

installations or when normal industrial drives

are unable to fulfil the requirements.

We supply ASTAT solutions for applications up

to 4000 A or 4700 kVA.

The ASTAT Digital Crane Motion Controller has

better control and information properties

compared to earlier controllers. Equally

important is the focus on quality of hardware

components. The digital controller can be

mounted on a steel plant crane in hot countries

such as India without extra cooling or air

conditioning. This capability provides additional

benefits to worldwide industrial crane users.

i.e. The crane control system must withstand

dirty, hot and cold environments in addition to

difficult power supply systems. This has forced

us to integrate functions like brake control, time

relays, logic control and thermistor relays into

the ASTAT controller. 

Regulations

Concerning the Setting up of Installations

Apart from the basic “Regulations of the Setting up of

Power Installations” DIN VDE*0100 and for “The Rating

of Creepage Distances and Clearances” DIN VDE 0110

Part 1 and Part 2 the regulations “The Equipment of Power Installations with Electrical Components” DIN VDE 0160

in conjunction with DIN VDE 0660 Part 500 have to be

taken into due consideration.

Further attention has to be paid to DIN VDE 0113 Part 1

and Part 200 in case of the control of working and processing machines. If operating elements are to be mounted near parts with dangerous contact voltage DIN VDE

0106 Part 100 is additionally relevant.

If the protection against direct contact according to DIN

VDE 0160 is required, this has to be ensured by the user

(e.g. by incorporating the elements in a switch-gear cabinet). The devices are designed for pollution severity 2 in

accordance with DIN VDE 0110 Part 1. If higher pollution

is expected, the devices must be installed in appropriate housings.

General setup rules

An ABB AC 31 system always includes an AC 31 central unit. There are three types of central units:

– The 40 series central unit, with a local inputs / outputs extensions interface

– The 50 series central unit, with a local inputs / outputs extensions interface

and a CS 31 bus interface

– The 90 series central unit, with a CS 31 bus interface

Each central unit incorporates a specific number of binary inputs / outputs and occasionally

analog. It is possible, depending on the central unit, to increase the number of inputs / outputs,

to add input / output extensions connected directly to the central units or remote input / output

units via the CS 31 twisted pair.

Central units with extensions

The 40 and 50 series. It’s possible to increase the number of inputs / outputs of the basic

central unit by adding up to 6 local extension units of either type, binary or analog (Figure 1-1).

2.2. Central units with CS 31 bus

The 50 and 90 series. It’s possible to increase the number of inputs / outputs of the basic

central unit by adding remote units. The central unit controlling the system is called the

MASTER central unit. The maximum bus length is 500 m without an amplifier and 2000 m with

3 amplifiers (1 NCB or NCBR unit enables bus amplification for 500 m).
