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. _x000D_ _x000D_ Features: _x000D_ 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. _x000D_ 2.
