Product Overview
Features:
Specifications:
Current: 0-20mA
Size: 8.5 x 7 x 4.2cm/3.34 x 2.75 x 1.65inch
Weight: 185g
The output impedance matching problem of the current generator:
The output signal must meet the following requirements
In addition, our current generator has some internal resistance.
So here's the formula:
Since
the power supply of our module is 4-35v, the constant current generated
by the module will not be sufficient if the power supply is low and the
customer's internal resistance is larger.
Power supply is 24V, the signal internal resistance ≤ 1000 Ω
Power supply is 12V, the signal internal resistance ≤ 500 Ω
Power supply is 5V, the signal internal resistance ≤ 200 Ω
If the internal resistance of your signal is higher than the above parameters, it can be used to solve the problem of insufficient current supply of the constant current source by improving the power supply voltage or by reducing the internal resistance of the signal. Note that the supply voltage cannot be increased to more than 28V.
