[DESCRIPTION] => According to IEC 61869 ENMU belongs to SAMU (Stand-Alone Merging Unit) class. ENMU provides Sampled Values (SV) data transmission according to Implementation Guidelines for Digital Interface to Instrument Transformers using IEC 61850-9-2 (IEC 61850-9-2LE).
ENMU comes with three optical fiber Fast Ethernet 100Base-FX interfaces, two of which can be configured to operate as a PRP node to provide seamless failover.
ENMU is an ultimate combo, transmitting up to four SV streams it can serve as a Phasor Measurement Unit (PMU) in compliance with IEEE C37.118.2 (up to 4 clients), while IEC 60870-5-104 (up to 4 clients) for legacy systems is supported too. IRIG-A, IRIG-B, PPS or PTPv2 can be used for time synchronization.

ENMU
ENMU meets IEC 61869-13 stand-alone merging unit standard. In addition to measuring inputs, ENMU may have digital inputs and outputs. Additional features of ENMU are
synchrophasor measurement and digital fault recording.
ENMU digitizes input current and voltage signals and publishes up to 4 streams of IEC 61850-9-2 sampled values (SV) to the process bus for protection and measurement. High sample rate streams can be used for energy metering and power quality monitoring by
ESM smart meters.
ENMU synchronizes the data using IEEE 1588v2 PTP. The modification with built-in digital inputs and outputs provides remote monitoring and control via IEC 61850-8-1 (MMS, GOOSE). The number of digital and analog signals processed can be increased by connecting external devices such as
ENMV-1.
ENMU provides IEEE C37.118 phasor measurements. ENMU records and stores fault oscillograms and phasor measurements. Pairs of interfaces for publishing SV streams, and communication via IEC 61850-8-1 (MMS, GOOSE) can operate in IEC 62439-3 PRP redundancy mode.
