Product Overview
The UR6PH is a plug-in digital I/O and phase measurement expansion module designed exclusively for GE Multilin UR Series universal protection relays. This module provides four isolated digital status inputs and six Form-A relay outputs, with integrated voltage and current metering functionality for electrical phase angle detection. It extends base relay hardware to interface with field auxiliary contacts, circuit breaker status feedback, trip circuits and local alarm devices. The module’s high-speed signal sampling supports precise fault sequence recording and coordinated protection logic. Substation automation engineers and maintenance teams rely on this expansion card to avoid full relay replacement when additional control and monitoring points are required, reducing upgrade costs and equipment downtime for existing protection systems.
Application Scenarios
- Power Substation Protection Panels: Expands UR series relays to monitor circuit breaker auxiliary contacts and drive trip/close coils. Accurate phase measurement enables directional overcurrent protection and simplifies coordination between upstream and downstream protective devices.
- Petrochemical Plant Auxiliary Power Systems: Monitors switchgear status on medium voltage distribution networks. Fast response time ensures timely fault logging and alarm signalling for uninterrupted critical process power supply.
- Renewable Energy Collector Substations: Used on wind and solar farm interconnection panels. GOOSE protocol support enables peer-to-peer interlocking between multiple UR relays for grid compliance and anti-islanding protection logic.
- Heavy Industry Medium Voltage Motor Control Centres: Provides remote status feedback for motor protection relays. Event sequence recording captures fault timestamps to accelerate root cause analysis after motor overload or short-circuit incidents.
