Zelio Control

Monitoring and Control Relays RM17 - RM22 - RM35 - REG

Part of Harmony

Zelio Control relays 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.
