Proven, State-of-the-Art Protection & Control Systems
The Universal Relay family of protection and control products are built on a common modular platform. All UR products feature high performance protection, expandable I/O, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The UR is the basis of simplified power management for the protection of critical assets.

Protection & Control
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.
Digital I/O
Up to 120 digital inputs (with utility voltage rating up to 250V), and up to 72 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.
Transducer I/O
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.
