In today’s energy-conscious world, monitoring electricity usage is no longer just a compliance task—it’s a strategic advantage. Whether you’re managing an industrial facility, a commercial building, or a large office complex, knowing exactly where and how your energy is consumed can save significant costs and improve operational efficiency.

The Rayleigh Instruments RI-D480 ‘Quad’ Multifunction Meter delivers a powerful solution in a compact package, combining four independent metering systems into one DIN-rail unit. Built with Rayleigh’s innovative EasyWire® technology, it’s designed for speed, safety, and scalability.

Why the RI-D480 Stands Out

The RI-D480 isn’t just another meter—it’s four meters in one. This means you can measure 4 separate three-phase loads or 12 single-phase loads using a single device. For busy electrical panels, that’s a huge space and cost saver.

The EasyWire® system is a game-changer for installers, reducing wiring time by up to 90% compared to traditional setups. The plug-and-play current transformer connections not only save time but also prevent open-circuit CT hazards, making installation safer.

Feature Highlights

  • Versatile Inputs
    Supports four 3-phase or twelve single-phase connections. Each load can have its own programmable CT and VT ratios.

  • True RMS Accuracy
    Delivers precise readings for voltage, current, power, power factor, frequency, and energy.

  • Scalable Monitoring
    Daisy-chain up to 32 meters using Modbus over RS-485. With a single voltage reference, you can monitor up to 128 three-phase or 384 single-phase circuits.

  • Clear, Easy-to-Read Display
    A crisp, white backlit LCD makes readings visible in all lighting conditions. Use the front panel buttons to scroll manually or let it auto-cycle through pages.

  • Pulse Output & Energy Indicators
    An integrated LED provides instant confirmation of energy flow.

The RI-D480 is ready for integration into your existing energy management systems. With RS-485 Modbus communication via “In” and “Out” ports, multiple units can be linked without complex wiring. This makes it ideal for large installations spread across multiple distribution boards.

The Rayleigh Instruments RI-D480 Quad Multifunction Meter delivers the insight, flexibility, and efficiency that modern energy monitoring demands. By combining four meters in one, integrating rapid-install EasyWire® technology, and offering scalable Modbus connectivity, it’s a smart investment for facilities that take energy management seriously.

Smarter metering starts here—compact, connected, and built for the future.
