About Output Impedance Matching:
Output signal must meet the following requirements
According to the formula:I=U/R(current = voltage/)
So the maximum current that signal receiving end can generate is equal to dividing power supply voltage by signal .
In this way, current generator still has some .
Thus concludes to a formula:
Power supply voltage/(signal internal + current generator internal ) = output constant current
Our module power supply is 5-32V voltage, so if using low voltage power supply, and the signal internal is large, the output constant current will not be enough.
Signal matching requirements is given below:
For 24V power supply, signal shall not be greater than 1000 ohms.
For 12V power supply, signal shall not be greater than 500 ohms.
For 5V power supply, signal shall not be greater than 200 ohms.
