Automation smart relays are designed for the management of simple automation systems offering logic control of simple processes. Control relays monitor and detect abnormal operating conditions, then initiate necessary corrective actions before serious and costly breakdowns can occur. Timers control a circuit at set daily intervals while counters offer and display usage stats like hours of operation.
