GE UR-8FH Part # UR8FH | Universal Relay Analog Module

GE Multilin UR8FH Universal Relay 8-Channel Analog Input Module

The UR8FH (Model: UR8FH) is a high-precision Analog Input Module (AIM) specifically engineered for the GE Multilin Universal Relay (UR) series. As a critical interface for power system monitoring, the UR8FH (Part Number: UR8FH) facilitates the acquisition of secondary signals from Current Transformers (CTs) and Potential Transformers (PTs). It translates these high-voltage/high-current electrical variables into a 16-bit digital format that the relay's central processing unit can use for protective logic, metering, and oscillography.

Built for utility-grade reliability, the UR8FH (Model: UR8FH) ensures signal integrity through comprehensive galvanic and optical isolation. This architecture prevents severe system transients—such as those occurring during a primary fault—from reaching the sensitive microprocessor backplane. The module is capable of supporting both current and voltage acquisition, making it the backbone for functions like overcurrent protection, distance elements, and power quality monitoring. Its wide operating temperature range ensures consistent performance in the most demanding substation environments, upholding the E-E-A-T (Expertise, Authoritativeness, Trustworthiness) standards of the GE Multilin series.
