4-20mA Current Voltage Signal Generator, with Battery Power Interface, Analog Simulator, Adjustable 4-Digit Display

Features: 1. Dual AMP and VOLT Signal: The multifunctional signal generator kit can generate both amps and voltage via a single module. Simply turn a precise potentiometer a few cycles to generate a current signal from 4 to 20 mA, making it easy and convenient. 2. Clear LED Display: Our 4-20 mA signal generator features a clear and bright 4-digit LED digital display that can be used to monitor the output current and voltage. You can easily switch between displays by simply pressing the switch located on the bottom of the display. 3. Amp and Voltage Display Calibration: There are calibration potentiometers for the current and voltage displays on the back of the module. If the display is inaccurate, you can calibrate the displayed current and voltage values ​​yourself. 4. Wide range of applications: Our signal adapters can be used for signal generators, valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, and analog transmitter output. 5. Good performance: Dual coarse and fine adjustment modes, and the number of turns can be set independently. The minimum adjustment value of the knob is 0.01 mA; the last digit is added or subtracted by 1. After calibration, the actual error is 0.01 mA, and high-precision linear output is achieved. 6. Reliable performance: Large, high-brightness 0.4-inch 4-bit digital tube; the display is clearly visible. Digital encoder knob, durable and insensitive to environmental factors. Power supply with reverse polarity protection. The output can be short-circuited.
