Features 1、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. 2、The converter module is to convert 0~500hz digital signal into 0~10V analog signal. 3、Input pulse level of 5/12/24V can be directly input without resistance.But input signal frequency should maintain more than 0.5 seconds. 4、All parts of the converter module are well-selected of good durability and high quality. 5、The module is stable and has great performance while using. Specification Features: The converter module is to convert 0~500hz digital signal into 0~10V analog signal. 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. Input pulse level of 5/12/24V can be directly input without resistance.But input signal frequency should maintain more than 0.5 seconds. All parts of the converter module are well-selected of good durability and high quality. The module is stable and has great performance while using. Specification: Size:4.5 x 4.7 x 1.7cm / 1.77 x 1.85 x 0.67in Relationship,Linearity: 50Hz to 1V 250hz to 5V 500hz to 10V Package List: 1 x Converter Module Note: At 24 levels, the power supply needs to be powered by 24VDC 3. The signal input end is isolated by diaphragm. Guaranteed anti-interference ability. 4. If you need to use PLC, support NPN type. Must have a ground wire. 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. 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. 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. Package List
