Generates 0/4 20 mA current signals and a 0 10 V voltage signal using a precision multi turn potentiometer. Key features Output options: 0 20 mA, 4 20 mA, and 0 10 V signals Precise control: multi turn potentiometer allows fine adjustment for accurate signal generation Flexible signal types: supports both current loop and voltage outputs for diverse applications Direct applicability: suitable as a signal source for testing, calibration, and control tasks Compatible applications Signal source generation for sensors, instruments, and transmitters Valve adjustment and control in hydraulic/pneumatic systems Inverter control and motor drive signals PLC debugging and analog input testing Instrument testing and calibration LED driver testing and debugging Analog transmitter output verification and testing Specific use scenarios Industrial control calibration: generate precise 0 20 mA or 4 20 mA signals to calibrate loops in valve control and inverter systems, and verify PLC analog inputs. Instrument and sensor testing: simulate transmitter outputs and validate instrumentation readings, PLC logic, and data acquisition paths. LED driver and analog transmitter testing: provide stable reference signals to test LED drivers and analog transmitters during development or maintenance. Debugging and adjustment procedure Current display correction 1) Rotate the multi turn potentiometer clockwise to the maximum position. 2) Move the display switch to the right. 3) Measure the actual current output with a multimeter. 4) Adjust the potentiometer to align the display reading with the measured current value, ensuring the display reflects the true output.
