            DI and DU Series Current and Voltage Monitoring Relays
                    Carlo Gavazzi’s relays provide invaluable protection for machinery against power anomalies
    

Image of Carlo Gavazzi's DI and DU Series Current and Voltage Monitoring Relays Carlo Gavazzi’s DI series of current monitoring relays can monitor both AC and DC currents. Current reading is made directly on the terminals, either through an external shunt or current transformer. Models such as DIA53 and DIB01 feature built-in current transformers that can read up to 100 A_AC. For applications with several hundred amps or more, external current transformers can be used with DI series monitoring relays.

The DU series of voltage monitoring relays can monitor both AC and DC single phase, from millivolts up to several hundred volts. With various models, under-voltage, over-voltage, or even both can be monitored and addressed before damage to machinery occurs.
