This specialized module acts as the critical sensory interface for utility and heavy industrial power systems. It continuously samples high-voltage and high-current waveforms from physical secondary instrument transformers, reducing them safely into digital data that the host relay uses for real-time protection algorithms, harmonic monitoring, and revenue-grade metering.\u003c\/p\u003e\n\u003cp\u003eThe architecture provides multi-channel configurations, typically offering 8 independent CT channels and 4 independent VT channels on a single faceplate assembly. This dense channel layout allows a single UR chassis to track comprehensive three-phase line currents, residual neutral currents, and bus voltages simultaneously.\u003c\/p\u003e\n\u003cp\u003eWe distribute this power system component exclusively in \u003cstrong\u003e100% brand new, original, and factory-sealed\u003c\/strong\u003e condition.
