4 to 20ma Signal Generator Adjustable DC 0 to 10V 0 Or 4 to 20mA Current Voltage Analog Simulator 1、Dual Signal Generator: This product can generate 0/4 to20mA current signal and 0 to 10V voltage signal by rotating a multi cycle precision potentiometer, which can be used as a signal source to produce output such as valve regulation. 2、Three Digit Display: Our signal generator has a bright and clear three digit LED digital display for monitoring output current and voltage. You can switch monitors easily by pressing the switch below the monitor. 3、Current and Voltage Calibration: Calibration potentiometers with current and voltage displays on the back of the module. If the display is accurate, you can calibrate the display value of the current voltage yourself. 4、High Accuracy: The LED display of the signal adapter displays current accuracy to 0.1mA, voltage accuracy to 0.01V, and the operating voltage is DC24V 5、Wide Applications: Our signal adapters can be used for signal generators, valve regulation, inverter control, PLC commissioning, panel commissioning, LED testing, analog transmitter output.
