Discover Harmony Control Relays
Harmony Control Relays monitor and detects abnormal operating conditions concerning phase, current, voltage, liquid level, frequency, speed, temperature, and pump control.
The relays inform users of abnormal conditions and allow them to initiate the necessary corrective actions before serious and costly breakdowns occur. By monitoring energy network statuses, they enable both electrical and mechanical load control.
Harmony Control Relays are suitable for a wide range of applications, such as hoisting, packaging, lifts, textile, pumping, and water.Video presentations
Advanced three phase control
With the new near-field communication (NFC) control relay, you can now enjoy greater accuracy, security, and enhanced monitoring within the palm of your hand.
Easy to use in all applications
Our control relays are designed with unique features to make them suitable for use in any conditions, including dusty or poorly lit environments.
Benefits of Harmony Control Relays
Comprehensive range
Wide monitoring parameters (phase, current, voltage, liquid level, frequency, speed, temperature, and pump control) to meet your application needs.
Increased efficiency
True root mean square (RMS) measurement that minimizes the possibility of unexpected trips from highly polluted networks.
Reduce troubleshooting time
Diagnostic button that helps you check the downstream circuit immediately without sending a fault input signal to the relays.
Advanced three phase control
Experience simplified product selection, unprecedented accuracy, predictive maintenance, and superior security with NFC Control Relay.

Harmony NFC Control Relays features
Simplified product selection and inventory management• One product reference covering 7 monitoring functions: phase loss, phase sequence, asymmetry, overvoltage, undervoltage, over frequency and under frequency.
Configure settings digitally via Zelio NFC App• Monitoring parameters can be set precisely to the desired value without the need for a screwdriver and complex calculations.• Time delay can be set precisely up to minutes, seconds or milliseconds.• Simulator available to check logic validity in settings.
Embedded with unique functions to help you save time• Auto-configure to “teach” the product to propose settings with real-time 3-phase network connections.• Clone settings to multiple NFC Control Relays easily with a simple click.• Settings can be shared via multiple channels (email, SMS, etc.) and loaded directly to another NFC Control Relay.
From product:• Front LEDs to indicate the exact fault statusVia Zelio NFC App:• Real-time monitoring of a relay status• Records a maximum of 20 faults through event logging
Set a four-digit password to prevent an unintended change of settings.
