Features:
- Protection input role: Provides the CT and VT signal-processing path for an applicable GE Multilin Universal Relay build.
- Module family: Uses the 8F standard 4CT/4VT arrangement represented by the installed option code.
- Host dependency: Requires the relay order code, slot, wiring, firmware and settings to be matched together.
UR8FH is used inside a compatible Universal Relay to bring current- and voltage-transformer signals into the protection and metering functions.
The module does not operate as a stand-alone measurement card; its behavior depends on the host relay hardware, firmware, slot assignment, CT/VT wiring and protection settings.
Keeping the complete UR8FH identity with the host-relay order code helps protection teams avoid a module that fits the chassis but does not reproduce the installed input arrangement.
Apter Power supports exact-model document review, quotation, and procurement for the General Electric UR8FH UR Relay CT/VT DSP Module.
