external process power.
Features and benefits
• Enables 2- and 3-wire connections of process signals.
• Direct mounting on the I/O module.
• Requires no extra space.
Spare parts health and functional check (on-site)
The spare parts critical to commercial operation (noble parts;
ex.: boards, power supply), will be installed directly on the
existing excitation system and the functionality of all parts will
be confirmed. This will require the excitation system and the
machine to be available for testing.
Spare parts health and functional check (at the factory)
Upon request, the health and functional check may be performed in
our factory. The spare parts must be carefully packed and shipped
to ABB. Once they arrive, they will be inspected and tested at our
supplier factory in order verify their correct functionality. We
recommend that spare part boards (PCB) containing electrolytic
capacitors should be tested every four years.
Parts Fingerprint
The Parts Fingerprint provides you with a complimentary
recommended spare parts list or, if a detailed list of the spare
parts is provided, a list of the recommended parts that are
missing can be prepared. This can be done, for example, as part
of a performance review. We will also keep you informed about
critical aging processes of vital components.
Product and part life cycle report (annual)
The Product Life Cycle annual report is a summary of the
excitation system parts availability and life cycle status. It will
also detail which new material can replace the obsolete ones and
if a mechanical adaptation is needed.
Control upgrade solution (preferential price)
ABB has designed a front-end control upgrade solution using the
latest excitation technology, the UNITROL 6000. for excitation
systems in the Limited or Obsolete phase. It is an efficient
solution that extends the life of the system and brings it to the
Active phase of the Product Life Cycle.
Performance review (preferential price)
The ABB performance review program is designed to ensure
the proper and safe operation of all your UNITROL excitation
products. We accomplish this by running tests on all critical
protection devices and system settings in various operating
conditions. We then prepare a report based on the findings, and
make recommendations on how to keep unplanned downtime at
a minimum.
Unlimited phone support
Technical phone support will be provided by the local support
center. During normal business hours (excluding holidays).
Technical support is also available for emergency cases, 24/7/365.
On-site troubleshooting dispatch prioritization
The ABB service hotline team will trigger an internal dispatch alert
and escalation process, immediately upon receiving customer’s
confirmation to dispatch a service engineer to site. The support
line will transfer all information and technical documentation
available for the service to the assigned service engineer.
Annual support usage report (available on demand)
ABB will provide an annual usage report on demand. This will
summarize all support activities provided during the Excitation
Care Program for a period of 12 months.
On-site critical spare parts assessment
The on-site critical spare parts assessment is designed to gather
all necessary information such as software and hardware version,
ABB reference number and quantity of the available spare parts
on-site directly from the customer site. It will then be compiled
in a detailed list by our specialist and provided to the customer
contact person.
Excitation Care provides peace of mind and reassurance to your maintenance team.
They will know who to call in case of emergency, theterms and conditions
of sale will be defined in advance; therefore, your maintenance team will
only focus on getting the best performance from your excitation systems.
Product Life Cycle notification (annual)
ABB will advise where the excitation systems are in the product
life cycle: Active, Classic, Limited or Obsolete. Customers will
receive recommendations depending on the status of the system.
It is a proactive approach to keep customers informed and to help
them plan excitation maintenance services efficiently.

The Relion 615 Series is a comprehensive family of protection relays per
fectly aligned for the protection, control, measurement, and supervision of
utility substations and industrial systems. It includes dedicated protection
relays for feeder, motor, and transformer protection.
The PCMU provides a seamless and cost effective way to re
place legacy relays. It reduces risk and saves money. A detailed
comparison of the PCMU series vs the traditional replacement,
which requires an adapter plate and is not wire-alike, shows
how users save time and money when replacing protection
relays and requires less personnel for less time.
The PCMU replaces DPUs of the 245. 445. and 2000 series
and MSOC relays. To request a training or quotation, contact
your ABB representative with the style numbers of your existing relays.
The PCMU represents the best choice to replace ABB
legacy relays. It ensures a reliable, seamless upgrade due
to the risk reduction only a wire-alike solution can provide.
It also offers the lowest possible cost of installation in
the market by allowing you to use the existing wiring and
connecting it into the wire-alike terminals*. Additionally,
the time to update drawings after installation is virtually
eliminated since no changes in wiring are required.
PCMU benefits:
− Relion® REF615 technology – Provides the ideal solution
to upgrade ABB’s DPU245. DPU445. DPU2000 and MSOC relays
− Installation time savings
− Pre-designed wire-alike and pre-configured relay solution
to quickly and efficiently carry out the replacement (retrofit)
and minimize downtime
− Wire-alike solutions, plate that contains terminal blocks
with connection to REF615 relay pre-wired based on appli
cation requirements
− Installation can be completed in as little as 40 minutes
− Form & fit– PCMU utilizes the existing cutout; no panel
modifications, cutting, or drilling is necessary (except MSOC)
− Engineering time savings – Save up to 70% of the time
required to update existing drawings after the upgrade
− Eliminate risk of setting conversions – Settings conversion
support is included to ensure your system keeps functioning
properly as soon as the new units are powered on
− Expanded communication capabilities – With the Relion
615. you can use Modbus, DNP3.0. or IEC 61850 for your
communications
− Advanced technology – Upgrade to the latest capabilities in
protection, control, metering, and fault recording

The PCMU MSOC is installed by using modern cutting tools
for fast and clean retrofit. The tool enables a precise quality cut
each and every time.
Bus protection via GOOSE
The IEC 61850 implementation in PCMU MSOC includes
fast peer-to-peer communication, over the substation bus.
Use GOOSE communication between PCMU MSOC relays of
the incoming and outgoing feeders of a substation to form a
stable, reliable, and high-speed busbar protection system. The
cost-effective GOOSE-based busbar protection is obtained by
configuring the relays and the operational availability of the pro
tection is assured by continuous supervision of the protection
devices and their GOOSE messaging over the station bus. No
separate hard-wiring is needed for the horizontal communica
tion between the switchgear cubicles.
Pre-emptive condition monitoring
For continuous knowledge of the operational availability of the
PCMU MSOC features, a comprehensive set of monitoring
functions to supervise the relay health, the trip circuit, and the
circuit breaker health is included. The breaker monitoring can
include checking the wear and tear of the circuit breaker, the
spring charging time of the breaker operating mechanism and
the gas pressure of the breaker chambers. The relay also mo
nitors the breaker travel time and the number of circuit breaker
operations to provide basic information for scheduling breaker
maintenance.
