Description
Signal Generator 4-20/0-20m 0-10v Digital Controller Constant Current Generator Electronic Measuring Meter Instruments
Product Description
1. Simple to use, convenient to connect, knob operation, response output immediately after adjustment, no delay. 2. Multi-turn (5 turns*360 degrees) potentiometer and single-turn (300 degrees) potentiometer are used for fine adjustment and smooth output. 3. The power port has polarity protection, the power connection does not work and does not burn components. 4. The error accuracy can be adjusted by itself, and the button on the back selects the digital tube to display current or percentage. 5. Power supply voltage: DC 9V~30V wide voltage input, the power of the whole machine is less than 1.5W. 6. DC 12V power supply, output end load impedance range between 0~350 ohm; DC 24V power supply, output end load impedance range between 0~800 ohm. 7. To test whether the output is normal, you can use a multimeter (DC current file) to short-circuit the "4~20mA output" terminal, and compare whether the displayed value is consistent with the reading of the multimeter. 8. The product can be used for: signal source generation, valve adjustment, inverter control, PLC debugging, instrument testing, light-emitting diode testing, analog transmitter output. 9. The meter head shell is easy to install. The overall size: width 80mm*height 42mm and depth 40mm, cabinet opening size: 76mm*40mm.
