MU360 is the Process Interface Unit (PIU) with analog and binary interfaces for full switchyard modeling, control and digitalization over IEC 61850 and IEC 61869 standards & protocols such as Sampled Value (SV) and GOOSE.

Key Benefits

• Compact form factor supports field installation options into circuit breakers cabinets, marshalling kiosks and metal-clad switchgear.
• Two slots for CT/VT analog boards supports application on breaker-and-a-half lines, dual distribution feeders, and combination protection and metering installations.
• 14 slots for I/O cards allows multiple applications. Apply as Merging Unit, Switchgear Control Unit device or PIU. Right size and point count for all type of application.
• High Speed High Break output contact option to directly operate into Circuit Breakers and Switchgears.
• Up to 4 SV streams IEC 61869-9/IEC 61850-9-2 Ed 2.1compliants for Protection and Metering profile.
• Full integration into the digital substation through up to 6 SFP interfaces, support for PRP and HSR redundancy protocols for availability networks, and IEEE 1588 Precision Time Protocol.
• Easy commissioning through simple EnerVista Flex 2.0, simulated Sampled Values and Test modes controllable per Logical Device to integrate multiple circuit breakers and disconnectors in one MU360.

Applications

• Process Interface Unit (PIU) for full bay digitization.
• Standalone Merging Unit (SAMU) for conventional instrument transformers.
• Switchgear Control Unit (SCU) for interfacing and control primary equipment such as circuit breakers and disconnectors.
• Yard unit for GE B30X distributed bus bar protection system.
• Revenue accuracy and power quality metering applications.
• Breaker-and-a-half line terminals using a single PIU device.
• Two feeders in a single PIU device.
