ABB PCMU The solution to mitigate risk and save costs on relay upgrades

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

− Reduced risk of human error - Controlled and repeatable

procedure for replacing existing protection relays with modern

protection relay allows users to implement as standardized solution.
