The N60 is the single point for protection, control, metering, and monitoring in one integrated device that can easily be connected directly into DCS or SCADA monitoring and control systems like Viewpoint Monitoring as shown.
FlexLogic is the powerful UR-platform programming logic engine that provides the ability to create customized protection and control schemes based on information measured locally by the N60 and received from remote N60s sent to it over the communications network. With FlexLogic, the N60 can use the status of measured inputs, along with the output of the protection elements, FlexElements and FlexMath summators, in Boolean logic equations to perform automated functions for customized special protection schemes.
The N60 contains FlexLogic and FlexMath equations that allow the creation of automated wide area protection and control schemes, remedial action schemes, and other special protection applications.

In addition to providing high-speed connectivity directly to your Universal Relay, the UR Switch Module provides an additional 4 fiber Ethernet ports, for connection to other relays in the system as well as upstream connectivity. It also provides 2 RJ45 copper Ethernet ports which can be used to connect local devices such as PCs, meters, or virtually anything else in the system.
The UR Switch Module provides a simple way to add fully-managed Ethernet networking to your relays and devices without the need for additional hardware or a dedicated communications cabinet.
The UR Switch Module includes all of the management and features that come with all MultiLink managed switches, and can be easily integrated into a network that has other Ethernet switches.
When used in a ring topology with other UR Switch Modules or MultiLink Switches, the UR Switch Module can be configured to use MultiLink’s Smart RSTP feature to provide industry-leading network recovery for ring topologies, at a speed of less than 5ms per switch.Learn More
