Features:_x000D_ _x000D_ The 0-3KHz frequency pulse signal is converted into a 0-10V analog voltage signal by this module. _x000D_ The module can be used for interface conversion between PLC and frequency converter or matching control of interface between motion control card and frequency converter. _x000D_ Input pulse level of 5V 12V 24V can be input directly without string resistance.But the input signal frequency, to maintain more than 0.5 seconds, the output current is 5mA. _x000D_ The multi-coil potentiometer on the board is used to calibrate the corresponding relationship between frequency and voltage. _x000D_ The optical isolate is used to ensure the anti-interference ability of the signal input. _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_ 300Hz to 1V_x000D_ 1.5Khz to 5V_x000D_ 3Khz to 10V_x000D_ _x000D_ Package List:_x000D_ 1 x 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.
