Dual-port or dual-function relay protection panels, such as the SEL-501, iRelay 50-P, SIPROTEC, and Multilin 850, are designed to provide redundant or independent protection for feeders, buses, transformers, motors, and breakers. These panels integrate multiple protection functions in a compact unit, often supporting two independent relays (Relay X and Relay Y) with separate inputs, outputs, and communication channels .
While exact dimensions vary by manufacturer, these panels are generally compact and modular, suitable for stacked switchgear or motor control centers. For example:
Dual-port information panels for relay protection are compact, modular, and highly configurable, providing independent protection channels, multiple digital and analog I/O, and communication interfaces for integration with SCADA or DCS systems. They are designed for redundant protection, flexible configuration, and easy installation in switchgear or motor control centers, with operational parameters tailored to specific protection requirements .
