Operation principle

The merging units (MUs) are situated close to the primary equipment, like circuit
breakers, isolators, etc. The MUs have the capability to gather measured values from
measuring transformers, non-conventional transducers or both. The gathered data are
then transmitted to subscribers over the process bus, utilizing the IEC/UCA
61850-9-2LE protocol.
The IED communicates with the MUs over the process bus via the rear access points.
For the user, the MU appears in the IED as a normal analogue input module and is
engineered in the very same way.
