Harmony Control Relays — Reliable Monitoring & Safety for Industrial Automation

Welcome to AGM Electrical Supplies, your premier Australian online source for high-quality industrial control and automation components. On our Harmony Control Relays page, you can effortlessly find top-tier Schneider Electric Harmony control relays—from classic analog models to cutting-edge NFC control relays. These units are engineered to maintain system reliability across a vast array of monitoring needs.

What Harmony Control Relays Do

Harmony control relays monitor critical electrical and mechanical conditions, such as phase loss, phase sequence, voltage, current, frequency, temperature, speed, and liquid level. Whether you're safeguarding motors from damaging phase issues or keeping pumps in check, these relays are your frontline defense against costly breakdowns.

Conventional vs NFC Smart Relays

While conventional control relays offer compact, modular, and reliable operation across RM17, RM22, RM35 series, the NFC relays elevate usability and intelligence. One NFC relay reference can support seven control functions—phase, asymmetry, over/undervoltage, and over/under frequency. Plus, setup is done via a smartphone app, with password protection, fault logging, and intuitive diagnostics.

High-Level Features That Matter

• True RMS measurement ensures stable operation even in noisy or distorted power environments, reducing nuisance tripping.
• Diagnostic button lets you test the downstream circuit instantly—no fault signal needed—streamlining commissioning and troubleshooting.
• Compact modular designs in standard widths (17.5 mm, 22.5 mm, 35 mm) make panel integration versatile and efficient.

Applications Built for Performance

Ideal for environments like lifts, escalators, packaging machinery, hoisting systems, data centers, HVAC, and pump stations, Harmony control relays are essential in industries demanding precision and uptime.
