WA-FR8/G frequency relay
The WA-FR8/G frequency relay measures the frequency of generators and motors. The principle is based on a frequency measurement of the generator’s voltage. The input range is 80 - 500 V AC. The measuring converter of the WA-FR8/G displays the frequency at the output as a standard signal 2-10 V DC.
Monitoring of underfrequency and overfrequency
In addition, the WA-FR8/G monitors the measurements for underfrequency and overfrequency. To indicate, a relay with changeover contact is available for each. In addition, the status is displayed on the device using LEDs. The tripping limits are predefined using a dip switch.
