Discover Harmony Control Relays
About 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 presentationsWith 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 applicationsOur control relays are designed with unique features to make them suitable for use in any conditions, including dusty or poorly lit environments.
