Your bridge from physical to digital worlds:

Process Interface Unit for Digital Substations

MU360 is the Process Interface Unit (PIU) with analog and binary interfaces for full

switchyard modelling, control and digitization using IEC 61850 and IEC 61869 standards and

protocols such as Sampled Values (SV), GOOSE, MMS and PTP.

The MU360 unlocks the full value of a completely digital substation, capable to be a single

I/O interface for Protection, Automation and Control applications to bay IEDs. Limiting the

field wiring just up to the MU360 reduces project complexity by reducing cabling, terminals,

and physical connections, which combined with a complete set of logical nodes allows

design standardization on the yard. Bay level IEDs can use data from redundant MU360

units, increasing system availability. Bay level IEDs can also be quickly replaced or added

using IEC 61850 test modes as no field wiring is involved. The MU360 has the additional

benefit of improving CT performance and cost through a lower connected burden and a

reduction in the number of CT cores required for an application.
