Monitoring

Monitoring

Voltage monitoring relays protect equipment from damage caused by faults in a DC or 1-phase AC system, such as overvoltage, undervoltage, or exceeding a voltage band. These relays are available in a selection of voltage inputs; certain models offer fixed or adjustable drop-out protection. Phase Monitoring Relays can help detect phase loss, phase reversal, and over/under voltage in 3-phase circuits. They can also help protect against phase unbalance. Safety monitoring relays respond to hazardous conditions to turn machinery on or off. They're used to stop equipment as well as monitor doors and guards to protect equipment and workers.
