In this way, current generator still has some resistance. Thus concludes to a formula: Power supply voltage/(signal internal resistance + current generator internal resistance) = output constant current Our module power supply is 5-32V voltage, so if using low voltage power supply, and the signal internal resistance is large, the output constant current will not be enough. Signal matching requirements is given below: For 24V power supply, signal resistance shall not be greater than 1000 ohms. For 12V power supply, signal resistance shall not be greater than 500 ohms. For 5V power supply, signal resistance shall not be greater than 200 ohms. If your signal resistance is greater than the above parameters, you can improve the power supply voltage or reduce internal resistance, to ensure a enough constant current source that the power supply voltage cannot be more than 32Vage Includes: 1 × Signal Generator
