The UR incorporates the most complete and unique protection algorithms to provide unparalleled security and system uptime. The UR selector guide (in the following pages) lists all the protection elements found in each relay.
To support the protection and control functions of the UR, various types and forms of I/O are available (specific capabilities are model dependent). Supported I/Os include:
CTs and VTs
Up to 24 analog current transformer (CT) and voltage transformer (VT) signals can be configured to monitor AC power lines. Both 1 A and 5 A CTs are supported. Special function modules are available including: a CT module with sensitive ground input to provide ground fault protection on high-impedance grounded systems; and a high impedance fault detection module that provides fast and reliable detection of faults caused by downed conductors.
Up to 96 digital inputs (with utility voltage rating up to 250V), and up to 64 digital outputs, are available and can be used to monitor and control a wide range of auxiliary equipment found within a substation or other protection application. Types of digital I/O cards include trip-rated Form-A, Form-C, Fast Form-C, Latching and Solid State with or without DC voltage, current monitoring and isolated inputs (with auto burnish feature). Mechanically latching outputs can be used to develop secure interlocking applications and replace mechanical switches and lockout relays. Form-A digital outputs have activation speeds of less than 4ms and both wet and dry contacts are supported. Solid state output modules with high current breaking capability, fast tripping and reset time are ideal for direct tripping applications.
RTDs and DCmA cards are available to monitor system parameters such as temperature, vibration, pressure, wind speed, and flow. Analog outputs can be used for hardwired connections from the controller to a SCADA system, to a programmable logic controller (PLC), or to other users.
The UR 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.

When used in a ring topology with other UR Switch Modules or MultiLink Switches, the UR Switch Module can be configured to use MultiLink™ Smart RSTP feature to provide industry-leading network recovery for ring topologies, at a speed of less than 5ms per switch.Learn More
The HardFiber Process Bus System represents a true breakthrough in the installation and ownership of protection and control systems, by reducing the overall labor required for substation design, construction, and testing. This innovative solution addresses the three key issues driving the labor required for protection and control design, construction and testing:
Every substation is unique making design and drafting a one-off solution for every station
Miles of copper wires needs to be pulled, spliced and terminated
Time consuming testing and troubleshooting of thousands of connections must be performed by skilled personnel
The HardFiber System was designed to address these challenges and reduce the overall labor associated with the tasks of designing, documenting, installing and testing protection and control systems. By specifically targeting copper wiring and all of the labor it requires, the HardFiber System allows for greater utilization and optimization of resources with the ultimate goal of reducing the Total Life Cost (TLC) for protection & control.
