Monitoring Relays

Monitoring Relays: Voltage, Current, Phase and Level

Monitoring relays watch a supply or process and switch a contact when it goes out of bounds – phase loss and sequence, over/under-voltage, current, frequency, temperature (PTC) and liquid level. We stock Carlo Gavazzi and Lovato Electric monitoring relays, level controllers and float switches, plus Finder, Pizzato and ABB units.

Filter by monitored quantity and supply voltage. For timing functions see time relays; for general switching see relays; for safety-rated monitoring see safety relays.
