Standardized communication

REF615 supports the new IEC 61850 standard for in

ter-device communication in substations. The relay

also supports the industry standard DNP3.0 and Mod

bus® protocols. The implementation of the IEC 61850

substation communication standard in REF615 en

compasses both vertical and horizontal communica

tion, including GOOSE messaging and parameter set

ting according to IEC 61850-8-1. The substation

configuration language enables the use of engi

neering tools for automated configuration, com

missioning, and maintenance of substation devices.

The cost-effective GOOSE-based busbar protec

tion is obtained by configuring the IEDs and the

operational availability of the protection is assured

by continuous supervision of the protection IEDs

and their GOOSE messaging over the station bus.

No separate hard-wiring is needed for the horizon

tal communication between the switchgear cubicles.

The REF615R is a dedicated feeder IED perfectly aligned

for the protection, control, measurement, and supervi

sion of utility substations and industrial power systems.

Application

The REF615R provides main protection for overhead lines,

cable feeders, and busbar systems of distribution substations.

It can be applied for protection and control of grounded and

ungrounded distribution systems.

One configuration tailored to meet and exceed these DPU2000R

ANSI and IEC configurations:

− Standard:  587R… (ANSI); 687R…(IEC)

− Synch Check:  587C…(ANSI); 687C…(IEC)

− SEF:  587E…(ANSI); 687E…(IEC)

The REF615R is designed for users looking for a 19” rack

mount form of ABB’s Relion® REF615. The REF615R utilizes

the same form and fit as the DPU2000R relay and provides

exact wire-alike matching rear terminals. This wire-alike

feature makes the REF615R the ideal solution for upgrad

ing to the industry’s latest technologies. The REF615R is

a member of ABB’s Relion family and part of its 615 pro

tection and control product series. The 615 series IEDs

are characterized by their compact, withdrawable design.

Engineered from the ground up, the 615 series has been

designed to unleash the full potential of the IEC 61850

standard for communication and interoperability of substa

tion automation devices while providing Modbus® and DNP

simultaneously in one standard configuration.

S800 I/O is a comprehensive, distributed and modular process I/O system

that communicates with parent controllers over industry-standard field buses.

Thanks to its broad connectivity it fits a wide range

of process controllers from ABB and other vendors.

By permitting installation in the field, close to sensors and

actuators, S800 I/O reduces the installation cost by reducing

the cost of cabling. And thanks to features such as “hot swap”

of modules, “on-line” reconfiguration and redundancy options,

it contributes to keeping production – and thereby profits – up.

Features and benefits

• Complete instalation of I/O modules using 3-wire connections and field power distribution.

• Up to 16 channels of field signals and process power connections.

• Connections to two ModuleBuses and I/O modules.

• Mechanical keying prevents insertion of the wrong I/O module.

• Latching device to DIN rail for grounding.

• DIN rail mounting

The TU842 MTU can have up to 16 I/O channels and 2+2 process

voltage connections. Each channel has two I/O connections and one

ZP connection. The maximum rated voltage is 50 V and maximum

rated current is 3 A per channel.

The MTU distributes the two ModuleBuses to each I/O module and to

the next MTU. It also generates the correct address to the I/O

modules by shifting the outgoing position signals to the next MTU.

The MTU can be mounted on a standard DIN rail. It has a mechanical

latch that locks the MTU to the DIN rail.

Four mechanical keys, two for each I/O module, are used to configure

the MTU for different types of I/O modules. This is only a mechanical

configuration and it does not affect the functionality of the MTU or

the I/O module. Each key has six positions, which gives a total

number of 36 different configurations.

The TU891 is a compact MTU for the S800 I/O. The MTU is a passive

unit used for connection of the field wiring and power supply to

the I/O modules. It also contains a part of the ModuleBus. The

TU891 MTU has gray terminals for field signals and process voltage

connections. The maximum rated voltage is 50 V and maximum

rated current is 2 A per channel, but these are primarily constrained

to specific values by the design of the I/O modules for their

certified application.
