Digital Adjustable Current Signal Generator Module Board Precision to 0.1mA frequency generator DIY Kit DC 12V 24V 4-20mA

Features:
Easy to use and connect the wire, good performance.
Knob operation, immediately after adjusting the response output, no delay.
The power port has polarity protection, will not damage the components with power reverse.
Power supply voltage: DC 12V or 24V(tolerance ±25%), total power<1W.
Output load impedance range: 0-350 ohms(DC12V); 0-800 ohms(DC 24V).
The test output is normal, you can use a multimeter shorted "4-20mA output" terminal.
Can be used for signal sources, valve adjustment, output meter test, the light emitting diode test, analog transmitter.
