Product Overview
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.

Frequently Asked Questions about UR-9NH
What is a UR-9NH used for the in universal relay system?
The UR-9NH is a CPU that may be contained in a variety of Multilin universal relays. Each of these relays has a different focus depending on the model of that UR. For example, the C90 plus is a breaker automation and controller. It is made to be used in substation settings in order to handle unique requirements of utility or industrial power systems in terms of automation. Its logic processing features are currently incomparable to other logic processing systems. Other universal relays are designed for other purposes. The T35 URs for example is used to protect multiple CTs as a basis transformer protection relay. Each of these Multilin universal relays need a central processing unit no matter their end function or application to the end user. These CPUs come in a variety of forms specified by a certain order code. In the case of a UR-9NH, the order code that designates this unit from other units is the 9N option. This 9N option is a newer designed CPU with a RS495 and a 10/100Base-T. In certain cases of URs, this new CPU will limit the version of the CT/VT, necessitating that the CT/VT is updated as well.
