Feature

●Input supply voltage range of 12-30V DC. (The voltage of 15-24V is recommended.) If the current level is 12 V, the supply voltage must not be 12 V. It is better more than 15 V. If the current level is 24 V, the supply voltage can be 24 V.
●The multi-circuit potentiometer board is used to calibrate the correspondence of frequency and voltage. The frequency of the pulse signal 0 Hz to 10 kHz converts into an analogue voltage signal of 0-10 V. Can be used for interface switching between the PLC and the frequency converter or for interface adjustment, e.g. B. for adjusting motion control card and converter control
●If the signal input is turbine flow, etc., an 817 optocoupler and resistor are needed to adjust the flow meter normally due to signal adjustment.
●Frequency/voltage converter module, the response time is approx. 0.3-0.5 seconds. For rotary encoders with constant speed, the encoder must continuously rotate more than 0.5 seconds. The input pulse level is 5V, 12V, 24V and can be entered directly without serial resistance. The input signal frequency must be longer than 0.5 seconds.
●The converter is intended for use with PLC supported NPN types. Must have an earth cable. Signal inputs with optical coupling separation. To ensure the ability of anti-interference.

Corresponding relationship:
If the F/V is transferred to an intermediate value with the resistor, F / V corresponds to the following relationship, 100 Hz = 0.1 V, the accuracy is 1%. It cannot reach up to 2 digits after the decimal point if a relatively high accuracy of the event is not sufficient.
0.1 V = 100 Hz, 500 Hz = 0.5 V, 1 kHz = 1 V, 2 kHz = 2 V, 3 kHz = 3 V, 4 kHz = 4 V, 5 kHz = 5 V, 6 kHz = 6 V, 7 kHz = 7 V, 8 kHz = 8 V, 9 kHz = 9 kHz = 9 V. V, V, 10 kHz = 10 V.
0.1 V DC each of the equivalent between the frequency 100 Hz. If the match is allowed, it can be corrected to adapt it to the board potentiometer
