GE UR9EH CPU Module

Technical Specifications 

General Electric Multilin’s UR-9EH is a CPU module intended for replacing a defunct module or upgrading an old module for a unit in the Universal Relays series. The module provides computing power to the relay in the form of logic algorithms, logic gates, latches, and timers. CPU modules do not require a surge ground connection.

Precautions

Users should note that new CPU modules must be used alongside new CT/VT modules; similarly, old CPU modules must be used alongside old CT/VT modules. Failure to do so will result in HARDWARE MISMATCH or DSP ERROR error displays, so users should ensure they are buying an appropriate module for the age of their module’s counterpart. GE Multilin’s UR-9EH has a number of configurable settings that impact CPU function and can be modified using the keypad and faceplate or EnerVista UR. For example, the SERVER SCANNING feature can be disabled to increase CPU resources, which is especially useful for users not requiring IEC 61850 client/server functionality. The CPU module’s Plug & Play capabilities also automatically establishes basic CPU settings, removing the burden of total programming from the user and allowing the user to focus on optimizing settings rather than starting from scratch.

Module Identification

There are many UR Multilin series universal relays with diverse functions and applications. The two Generation UR relays are the G60 and the G30. The G60 is designed for medium or large generators (primary and backup protection) and the G30 is designed for medium and small generators to provide comprehensive monitoring features in addition to protection of the generators. Additionally, the bulk of the UR relays fall into the transmission or distribution category. The L30 for example provides line current differential protection for sub-transmission lines whereas the D30 provides backup distance protection for transmission systems. There are more than eighteen UR relays in addition to the ones briefly mentioned here. Each of these universal relays is equipped with a CPU whether the universal relay is a vertical (3/4 size) or a horizontal mount relay. The CPUs can be identified by a RH-9 part introduction, followed by a letter that designates the specific characteristics of that CPU. The CPUs of the 9A, 9C, or 9D category will be of the old module types and the other letters (9E and up to 9S) will indicate a new CPU module contained in the universal relay.
