PRODUCT INFORMATION
Product Overview
General Electric UR-9NH is a Multilin Processor Module designed for Universal Relay platform installations. The unit executes protection algorithms, logic gates, latches, and custom control frameworks. It processes electrical data collected across adjacent modules, including CT and VT instrumentation cards. The module operates alongside power supply units, transducer interfaces, and digital input or output cards. Integrated self-diagnostic routines generate explicit error codes during hardware or calculation faults.
This central processing unit does not require a dedicated surge ground connection during installation. Eliminating the surge ground conductor decreases panel wiring complexity and auxiliary mounting hardware requirements. The assembly measures approximately 6.5 inches long, 6 inches wide, and 2.5 inches high. It weighs approximately 1 pound and 10 ounces. Manufacturing of the hardware took place in Markham, Ontario, Canada.
