The Current Analog Signal Generator can be connected with the power supply to generate 4-20MA constant current signal output. The digital display shows output current in mA and the accuracy is one decimal place. The signal generator is designed internally with various protection circuits. It is characterized with pure output signal, stable and reliable performance, which can be widely used for inverter control, PLC debugging, valve adjustment, instrument test, LED test, analog transmitter output, signal source generation, etc. Features: 1. The current signal generator uses 4 male and female head socket for convenient wiring and maintenance and reserves 5.08mm interval for safe use. 2. It adopts high quality potentiometer with ultra long life and high wear resistance. 3. Coarse tuning and fine tuning dual potentiometer make it convenient to accurately control current signal output. 4. 0.56 inch high-brightness digital tube display ensures display effect under long-distance and strong light. 5. Power supply input has reverse connect protection function and self-recovery fuse protection function, 6. The signal output has lightning protection, anti-ESD protection and anti-interference protection.
