About the UR-9NH
General Electric Multilin’s UR-9NH is a CPU Module designed for installation in the Universal Relays series. The module offers the Universal Relay unit computing power through complex algorithms, logic gates, latches, and logic frameworks. The module also works closely with other modules of the series, assisting in determining parameters collected and general functions, especially alongside the CT/VT modules. Aside from the CPU module and CT/VT module, other modules in the series include the transducer input and output, power supply, contact input and output, and inter-relay communications.
One of the major benefits of the UR-9NH relay is that it is produced by General Electric Multilin, a highly organized company with a large array of technical support documents for wiring, installation, and daily operation. The Universal Relay manuals contain highly specific instructions for maximizing the efficiency of the CPU module while reducing the potential for system harm and user injury. The module is also capable of self-diagnostics, providing error codes to reduce the amount of time users need to hunt for support information.
The CPU module does not require a surge ground connection, cutting down on the amount of wiring and auxiliary equipment required by the user.
