Pre-Configured Matching Unit (PCMU)

The PCMU represents the best choice to replace ABB legacy relays.

ABB offers an alternative to upgrade legacy relays using the Relion 615 Series of Intelligent Electronic Devices in a simple, easy to install, retrofit assembly. These retrofits, which replace existing ABB legacy relays such as DPU, DPU2000, TPU2000, IMPRS, and Pro*Star, allow the user to take advantage of features provided by the 615 Series such as high impedance fault detection, improved fault recording capabilities, upgraded communication protocol or port, and even add arc-flash detection. Flexitest test switches can also be added to the retrofit.
The 615 series has been designed to unleash the full potential of the IEC61850 standard for communication and interoperability of substation devices including fast, horizontal relay-to-relay (GOOSE) communications for cost-effective, reliable and high-speed control schemes.

The retrofit assembly comes with the same rear terminal block layout as the existing relay, reducing the installation time while ensuring that the existing wiring and its terminal connectors can be connected to the retrofit assembly “as is”, without the need for any modifications.
