Dual Signal Generator: This product generates a 0/4 to 20mA current signal and 0 to 10V voltage signal by rotating a multi-cycle precision potentiometer, serving as a signal source for applications such as valve regulation. Three Digit Display: Features a bright and clear three-digit LED digital display for monitoring output current and voltage. Monitor switching is easily performed by pressing the button below the display. Current and Voltage Calibration: Includes calibration potentiometers with current and voltage indicators on the rear of the module. If needed, users can manually calibrate the current and voltage display values. High Accuracy: The LED display provides current accuracy to 0.1mA and voltage accuracy to 0.01V. Operates at DC24V. Wide Applications: Suitable for use as a signal generator in valve regulation, inverter control, PLC commissioning, panel testing, LED testing, and analog transmitter output.
