F4080 is a digital measuring, fully programmable device from the 4080 series, designed on the basis of microcontrollers. The device is used to measure frequency (50/60 Hz) in electrical substations and power plants.
F4080 is powered by the measured AC voltage. F4080 has potential-free contacts for remote signalisation if the measured frequency goes out of a certain specified range (option “R”). The unit is designed to be mounted on boards in control rooms of electrical substations.
