Features:_x000D_ _x000D_ The converter module is to convert 0~500hz digital signal into 0~10V analog signal. _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 5/12/24V can be directly input without resistance.But input signal frequency should maintain more than 0.5 seconds. _x000D_ All parts of the converter module are well-selected of good durability and high quality. _x000D_ The module is stable and has great performance while using. _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_ 50Hz to 1V_x000D_ 250hz to 5V_x000D_ 500hz to 10V_x000D_ _x000D_ Package List:_x000D_ 1 x Converter Module_x000D_ _x000D_ Note:_x000D_ 1. The multi-turn potentiometer on the board is used to calibrate the corresponding relationship between frequency and voltage._x000D_ 2. 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. If you need to use 12V power supply, you can also order 12VDC. Power converter._x000D_ At 24 levels, the power supply needs to be powered by 24VDC_x000D_ 3. The signal input end is isolated by diaphragm. Guaranteed anti-interference ability._x000D_ 4. If you need to use PLC, support NPN type. Must have a ground wire._x000D_ 5, if you need to use the encoder, the encoder is required to continue to rotate at a constant speed for more than 0.5 seconds._x000D_ 6, frequency and voltage conversion module, response time is about 0.3-0.5 seconds._x000D_ 7. 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_ 8. 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.
