Monitoring relays

Carlo Gavazzi's monitoring relay range covers most automation industry requirements, single and three-phase, current, motor management, earth leakage, frequency, temperature and pump management. They are used in many applications to protect loads, machinery or people from dangerous situations (elevators, compressors, pumps, air conditioning systems, mixing tanks). Process signals can also be monitored (4-20mA, 0-10V) for machinery operation verification.
