UR9NH General Electric CPU MODULE

The UR9NH 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.
