GE FANUC | UR-8LH | UR 8LH | UR8LH | CT/VT Module

Description

The GE FANUC UR8LH CT/VT Module is a dedicated input module designed for the Universal Relay series, engineered to measure electrical circuit current and voltage while delivering multi-functional protection capabilities. It supports module replacement, system upgrades, or adds new functionality to relays not originally equipped with such modules. Key features include interfaces for 4 current transformer (CT) and 4 voltage transformer (VT) inputs, plus enhanced diagnostic functions that verify analog signal integrity, detect saturation, open circuits, and polarity errors to boost system reliability. The module scales CT and VT values for relay ratio calculations, with accessible data via front-panel LCD or the EnerVista UR software. Technical specifications include 0.5 class or higher VT input accuracy, MODBUS communication support, operating temperature range of -25 degrees Celsius to +70 degrees Celsius, and storage temperature range of -40 degrees Celsius to +85 degrees Celsius. It has an IP20 protection rating, uses DIN rail mounting, and carries CE, UL certifications. Fully compatible with other Universal Relay series modules, it is ideal for applications in industrial automation (motor control, variable frequency drive control, power distribution protection), power systems (substation protection, distribution automation), and process control (chemical, metallurgy monitoring and control).
