Product Description
The GE Multilin UR81H is an IEC 61850-based Process Bus Module designed for the GE Multilin Universal Relay (UR) series. It provides an eight-port digital process bus interface enabling modern digital substation architectures where CT/VT measurement and sampled-value streams are communicated over Ethernet instead of conventional copper wiring. The module enhances protection, control, metering, and automation by delivering precise digitization of analog signals (from CTs/VTs) into IEC 61850 sampled values, supporting advanced protection applications in industrial and utility environments. Its modular, hot-swappable design reduces downtime during maintenance and system upgrades, and it supports IEEE 1588 time synchronization plus cybersecurity features aligned with industry standards.
