CARLO GAVAZZI DFC01DB23 Frequency Monitoring Relay
The Carlo Gavazzi DFC01DB23 frequency monitoring relay provides precise monitoring of power supply frequency. It offers two independent setpoints for over and under-frequency conditions, along with adjustable delay times. This relay is ideal for applications requiring reliable frequency monitoring, such as industrial automation, power systems, and motor protection. The DFC01DB23 is DIN-rail mountable and features LED indication for relay status, alarm, and power supply.
