What is a Monitoring / Measuring Relay?
A monitoring / measuring relay is a protective control device, various types are available suiting what you wish to monitor. The relays receive input signals then monitor them and then output an alarm signal when a set value is reached (alarm relays). The relays protect your equipment against over voltage and over current faults. Monitoring relays monitor AC power supplies, voltage and current, analogue signals detecting unusual activity in equipment against set alarm thresholds.
Types of Monitoring Relays Available?
? Motor protection relays
? Temperature monitoring relays
? Water level control relays
? Voltage
? Current
