Frequency meter FMD6-2N/220V
f=(30.00 ÷ 80.00 Hz), Us=220Vac, 2 outputs 4A/220V, 95x49x113mm
The FMD6-2N/220V digital frequency meter is a microprocessor device with a 6-digit display and serves for measuring the network frequency (40-60Hz). The device receives information about the network frequency from the supply voltage. The frequency meter has two output relays and can be set two limit frequencies "F1" and "F2" in reaching of which the relevant output relay switches on. The frequency meter is designed for installation in a dashboard (panel montage).
FEATURES
The FMD6-2N digital frequency meter is a microprocessor device used to measure the mains frequency of 40÷60Hz at a supply voltage of 220Vac (110Vac option). There is no input for connecting on a sensor or for receiving pulses from a generator. The frequency meter uses the frequency of the electrical network in which it is connected. The frequency meter has two output relays and can be set two limit frequencies "F1" and "F2" in reaching of which the relevant output relay switches on.
