This module has 16 digital outputs. The output voltage range is 10 to

30 volt and the maximum continuous output current is 0.5 A. The

outputs are protected against short circuits, over voltage and over

temperature. The outputs are divided into two individualy isolated

groups with eight output channels and one voltage supervision

input in each group. Each output channel consists of a short circuit

and over temperature protected high side driver, EMC protection

components, inductive load suppression, output state indication

LED and optical isolation barrier.

The process voltage supervision input give channel error signals if

the voltage disappears. The error signal can be read through the

ModuleBus. The outputs are current limited and protected against

over temperature. If the outputs are overloaded the output current

wi l be limited.

The DO820 is an 8 channel 230 V a.c./d.c. relay (NO) output module

for the S800 I/O. The maximum output voltage is 250 V a.c./d.c. and

the maximum continuous output current is 3 A. Al outputs are

individualy isolated. Each output channel consists of optical

isolation barrier, output state indication LED, relay driver, relay and

EMC protection components. The relay supply voltage supervision,

derived from the 24 V distributed on the ModuleBus, gives an error

signal if the voltage disappears, and the Warning LED turns on. The

error signal can be read through the ModuleBus. This supervision can

be enabled/disabled with a parameter.

Features and benefits

• 8 channels for 230 V a.c./d.c. relay Normal Open (NO) outputs

• 8 isolated channels

• Output status indicators

• OSP sets outputs to predetermined state upon error detection

MR Series controllers

Melody controllers are designed for maximum

computing power and modular scalability.

Each controller can handle up to 2.000 analog

and/or digital I/O points from the local I/O, and

additionally 6.000 analog and/or digital I/O

points connected via PROFIBUS DP. In addition

to the standard tasks such as signal processing,

loop and logic control, the MR Series controller

also performs complex computations such as

sequential, batch and advanced controls.

Diagnostic routines periodically check the

hardware and firmware integrity. 

Each node on the control network operates

autonomously. Acting as its own communication

manager, the system requires no traffic directors.

The controller’s associated I/O modules are

connected using the high-speed redundant serial

field network or PROFIBUS DP (DPV1 as well as DPV2).

Wide range of intelligent I/Os, standard interfaces and libraries

Scalable control stations

MR Series control stations are conveniently

set up according to project needs and are made

up of modular controllers and I/Os. Depending on

the scope of the automation task, the controller

is extended with I/O modules or communication interfaces.

The controllers are connected via the control

network to ensure reliable, high speed and

system wide real-time signal exchange with

other control stations, with S+ Operations,

with system level applications and with

S+ Engineering for Melody.

manager, the system requires no traffic directors.

The controller’s associated I/O modules are

connected using the high-speed redundant serial

field network or PROFIBUS DP (DPV1 as well as DPV2).

The control subsystem includes flexible

communication options to I/O and intelligent

field devices via system buses. HART as well as

PROFIBUS information, including configuration

and diagnostic information, is communicated

via the control network. This information is

available to system controllers and system

level applications such as asset optimization

and device management. The comprehensive

bus concept of the system controller allows

for the easy integration of HART, PROFIBUS,

Modbus RTU and TCP field devices as well as

of PROFIBUS and IEC 61850 electrical assets.

The MR Series functional capabilities are

summarized in figure 2.

Key features include:

• A wide range of I/O interfaces with optionally

integrated intrinsic safety (Ex i) design and

transmitter power supply. Features such as

time stamping with a 1 ms resolution,

monitoring, filtering and HART communication

are implemented directly in the I/O modules

• PROFIBUS interfaces provide connections to

ABB’s S800 and S900 remote I/O stations in

Ex and non-Ex versions, as well as other PROFIBUS devices

• IEC 61850 interface to intelligent electronic

devices (IEDs) for the integration of electrical subsystems

• Modbus RTU and TCP interfaces provide

connections to 3rd party devices

• The MR Series control network uses a

redundant, high-speed serial communication

network with inherent capability for remote

communication. The network is easy to handle,

without requiring routing configuration

• Flexible mounting alternatives such as cabinet,

DIN rail or 19” rack mounting. All three can be

combined in one project. This allows optimal

adaptation to all plant structures and supports

flexible upgrades of existing installations

• An unrivaled high packing density in the

system cabinets saves installation space

• Controller time synchronization based on

a time precision of 0.5 msec

• Sequence of events (SOE) time stamping

with a resolution of 1 ms is implemented

in the controller and local I/O module level

Overview

The MR Series includes a series of compact DIN

rail mounted controllers, a wide range of I/O

modules and modern, standardized fieldbus

interfaces. These modules offer all the

functions required for data acquisition and signal

conditioning, as well as powerful open loop

and closed loop control, sequence control and

monitoring. All process management

tasks are executed on the basis of integrated

complex control strategies. Without the need

for configuration, The MR Series inherent

redundancy design – including integrated

redundancy concepts for power supply,

communication and I/O – provides the highest

level of availability.

ABB Ability Symphony Plus MR Series (Melody

Rack) controllers, communication interfaces

and I/O modules meet the most challenging

requirements in each of these areas.

Thanks to their modular design, MR Series

controllers can be adapted to a wide variety

of plant types and sizes. Supported by an

efficient engineering workbench, MR Series

control based solutions contribute to a higher

return on assets by improving overall production

control, maximizing process availability, and minimizing maintenance.

Traditionally, production facilities maintained

many controller subsystems, each of which

had to meet specific plant needs. However,

as business goals have changed, using a scalable

controller platform that possesses multi

functional capabilities, adapts to changing

requirements, and maximizes openness and

availability, is paramount to success.
