Harmony Control Monitoring and Control Relays (RM17, RM22, RM35) monitor and detect abnormal operating conditions concerning phase ,current, voltage, frequency, speed, or temperature. The relays inform users of abnormal conditions and allow them to initiate the necessary corrective actions before serious and costly breakdown can occur. Harmony phase control relays detect all possible faults occurring in the phases. Harmony voltage and current control relays ensure your equipment is powered with proper values. Harmony frequency control relay monitors frequency variation from your power generation line. It provides automatic shutdown management and fault information to user for a quick fault identification and troubleshooting. Harmony pump control relay controls and protects your pump from dry running or overloading. Harmony speed control relay picks up the improper rhythm of your process. Harmony temperature control relay for lift application is a dedicated to elevator temperature monitoring (EN81). Harmony temperature control relays are dedicated to temperature regulation (heating, cooling or heating/cooling of processes). These Harmony relays are available in 17.5 mm, 22.5 mm or 35 mm wide housings and are DIN rail mounted. Applications for these Harmony relays include hoisting, construction cranes, harbor cranes, packaging, construction elevators, passenger elevators, escalators, textile, water and waste water.
