4 - 20mA Signal Source Constant Current 0.01mA Signal Generator DC 12V- 24V
Features: Easy to connect wire and use, knob operation. In response to the output immediately after adjustment, no delay. Adjust the actual fineness of up to 0.01mA, operate freely. With polarity protection, power reverse does not work, do not burn components. Power supply voltage: 12V DC or 24V (tolerance 25%), Total power 1W . Output load impedance range between 0-350 ohms(DC 12V); 0-800 ohms(DC 24V). Can be used: signal sources, regulating valves, test instrumentation, light emitting diode test, the inverter output analog transmitter.
