Frequency meter FMD6-2/12-24V
f=(0.05 ÷ 9999.99 Hz), Us=12÷24V ac/dc, 2 outputs 4A/220V, 95x49x113mm
The FMD6-2/12-24V digital frequency meter is a microprocessor device with a 6-digit display and serves to measure the frequency of positive electrical impulses with amplitude 3-30VDC in the range from 0,05 to 9999,99Hz. The device can work together with sensor type "PNP" connected to its input. 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 device is designed for installation in a dashboard (panel montage).
The FMD6-2 digital frequency meter is a compact microprocessor device that is used to measure and controlling the frequency of rotation of axes and other rotating objects in hertz (Hz). The frequency meter input is designed to work with PNP sensors. It can also work with NPN sensors with the addition of a resistor. The device can be used to measure the frequency of generators of positive electrical pulses. 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.
