Description/Features: The 4-20mA Current Voltage Signal Generator is a versatile tool designed for various applications including signal generation, valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, and analog transmitter output. It features a dual signal capability, allowing users to generate both ampere and voltage signals from a single module. Adjustments are made through a multi-cycle precise potentiometer, offering both coarse and fine tuning modes. The device boasts a clear 4-digit LED display for monitoring output current and voltage, with easy switching between displays at the of a button. Calibration potentiometers for current and voltage are conveniently located on the back of the module, enabling users to fine-tune the display accuracy. The unit is designed for reliability with a digital encoder knob that is and unaffected by environmental conditions, and includes reverse polarity protection and short-circuit capability on the output.
