Features: _x000D_ 1. Convert the 0-500Hz frequency pulse signal into an analog voltage signal of 0-5V. _x000D_ 2. Can be used to Convert interface between PLC and frequency, Or movement control card and converter interface matching control occasions. _x000D_ 3. Input pulse level is 5V 12V 24V can be directly input, no string resistor. However, the input signal frequency should be maintained for more than 0.5 seconds. _x000D_ 4. The output current is 5MA. _x000D_ 5. Frequency and voltage conversion module, response time is about 0.3-0.5 seconds. _x000D_ _x000D_ Specification: _x000D_ Condition: 100% Brand New _x000D_ Item Type: Frequency To Voltage Conversion Module _x000D_ Model: FV-500Hz5V _x000D_ Function: Input 0-500Hz frequency is converted to 0-5V _x000D_ Output Current: 5MA _x000D_ Response Time: 0.3-0.5 seconds _x000D_ Size: Approx. 4.5 x 4.7 x 1.7cm / 1.8 x 1.9 x 0.7in _x000D_ _x000D_ Package List: _x000D_ 1 x Frequency To Voltage Conversion Module _x000D_ _x000D_ Precautions for use: _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. Powered converter. At 24 levels, the power supply needs to be powered by 24VDC _x000D_ 3. The signal input is isolated by diaphragm. Guaranteed anti-interference ability. _x000D_ 4. For use with PLC, support NPN type. Must have a ground wire. _x000D_ 5. If you need to use an encoder, the encoder should be rotated 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. When using the correspondence, if there is a deviation, you can adjust the blue potentiometer on the board to adjust. 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_ _x000D_ Identification and wiring: _x000D_ 1. 12-30V--Power input positive _x000D_ 2. GND--Power input negative (common ground wire) _x000D_ 3. GND--Pulse frequency input negative (common ground wire) _x000D_ 4. 0-10KHZ--Pulse frequency input positive _x000D_ 5.
