Zelio 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. Zelio phase control relays detect all possible faults occurring in the phases. Zelio voltage and current control relays ensure your equipment is powered with proper values. Zelio frequency control relay monitors frequency variation from your power generation line. The product monitors its own power supply, when the power supply is abnormal, the output relay de-energizes. Zelio pump control relay controls and protects your pump from dry running or overloading. Zelio speed control relay picks up the improper rhythm of your process. Zelio temperature control relay for lift application is a dedicated to elevator temperature monitoring (EN81). Zelio temperature control relays are dedicated to temperature regulation (heating, cooling or heating/cooling of processes). These Zelio relays are available in 17.5 mm, 22.5 mm or 35 mm wide housings and are DIN rail mounted. Applications for these Zelio relays include hoisting, construction cranes, harbor cranes, packaging, construction elevators, passenger elevators, escalators, textile, water and waste water.
