Features:_x000D_ _x000D_ Convert the 0-500 Hz frequency pulse signal into an analog voltage signal of 0-10V. Can be used for interface conversion between PLC and inverter. Or the motion control card and the inverter and other interfaces match the control occasion. _x000D_ The input pulse level of 5V 12V 24V can be directly input, without string resistance. However, the input signal frequency should be maintained for more than 0.5 seconds.The output current is 5mA. _x000D_ The multi-turn potentiometer on the board is used to calibrate the corresponding relationship between frequency and voltage. _x000D_ The input power supply voltage range is 12-30VDC. It is recommended that the power supply voltage be 15-24VDC. When the 12V level is used, the power supply cannot be powered by 12VDC,at least 15VDC power supply is required. When the 24V level is used, the power supply needs to be powered by 24VDC. _x000D_ The signal input end is isolated by diaphragm. Guaranteed anti-interference ability. _x000D_ _x000D_ Specification:_x000D_ Item Type:Frequency to Voltage Converter Module_x000D_ Model:FVS-500Hz10V_x000D_ Conversion:0~500Hz to 0~10V_x000D_ Output Current:5mA_x000D_ Size:7.3 x 5 x 2.8cm / 2.87 x 1.97 x 1.1in _x000D_ Correspondence Relationship(Linearity)_x000D_ 50Hz converted to 1V_x000D_ Convert 250Hz to 5V_x000D_ Convert 500Hz to 10V_x000D_ _x000D_ Package List:_x000D_ 1 x Converter Module with Shell_x000D_ _x000D_ Note:_x000D_ If you need to use PLC, support NPN type. Must have a ground wire._x000D_ If you need to use with the encoder, the encoder is required to continue to rotate 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 normal function._x000D_ Correspondence in use If there is a deviation, 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.
