The GE UR9EV Multilin Processor Module CPU is a high‑performance CT/VT module designed for the Universal Relay (UR) platform. It supplies phase and ground current transformer inputs along with four‑terminal voltage transformer inputs, enabling precise monitoring and protection of AC power systems. Its advanced diagnostic algorithms ensure signal integrity and early detection of abnormal conditions, improving system reliability and operational safety.
The UR9EV module provides essential CT/VT interfacing for Multilin UR relays, enabling accurate measurement of phase currents, ground currents, and system voltages. Its built‑in diagnostic algorithms continuously validate analog signal quality, helping operators detect wiring issues, transformer faults, or abnormal operating conditions before they escalate.
The module supports straightforward installation using standard AWG wiring and can be used to:
Replace older CT/VT modules
Upgrade existing UR relay systems
Add CT/VT capability to relays lacking these functions
