Features:_x000D_ _x000D_ The module is to convert frequency pulse signal of 0-5 KHz into an analog voltage signal of 0-10V. _x000D_ The converter can be used for interface conversion between PLC and inverter or interface matching control between motion control card and inverter. _x000D_ The input pulse level of 5V 12V 24V and can be directly input without string resistor. But the input signal frequency should be maintained for more than 0.5 seconds, and the output current is 5mA. _x000D_ The optical isolate is used in the input end of the signal to ensure the anti-interference ability. _x000D_ The multi-coil potentiometer on the board is used to calibrate the corresponding relationship between frequency and voltage. _x000D_ _x000D_ Specification:_x000D_ Item Type:Frequency to Voltage Converter Module_x000D_ Size:4.5 x 4.7 x 1.7cm / 1.77 x 1.85 x 0.67in _x000D_ Relationship,Linearity:_x000D_ 500Hz to 1V_x000D_ 2.5Khz to 5V_x000D_ 5Khz to 10V_x000D_ _x000D_ Package List:_x000D_ 1 x FV-5KHz10V Frequency to Voltage Converter Module_x000D_ _x000D_ Note:_x000D_ For use with PLC, support for NPN type. Must have a ground wire._x000D_ If you need to use an encoder, you need to keep the encoder running at a constant speed for more than 0.5 seconds._x000D_ Frequency and voltage conversion module, response time is about 0.3-0.5 seconds._x000D_ If the signal input is turbine flow, etc., due to signal matching, an 817 diaphragm and a resistor must be added to match the flowmeter to function properly._x000D_ If there is a deviation in the correspondence when using, you can adjust the blue potentiometer on the board to calibrate. At the time of shipment, we have adjusted the F/V potentiometer to a certain correspondence. It is generally not recommended to adjust it by itself._x000D_ Input power supply voltage range is 12-30 VDC, recommended supply voltage 15-24 VDC.When at 12V level, the power supply can not use 12VDC power supply, at least 15 VDC power supply, if a certain need to use 12V power supply, can also be customized 12VDC power supply converter. When at 24V level, the power supply need to use 24VDC power supply.
