The CurrentAnalog Signal Generator can be connected with the power supply to generate4-20MA constant current signal output. The digital display shows output currentin mA and the accuracy is one decimal place. The signal generator is designedinternally with various protection circuits. It is characterized with pureoutput signal, stable and reliable performance, which can be widely used forinverter 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 forconvenient wiring and maintenance and reserves 5.08mm interval for safe use. 2. It adopts high quality potentiometer with ultra long life and highwear resistance.3. Coarse tuning and fine tuning dual potentiometer make it convenientto accurately control current signal output.4. 0.56 inch high-brightness digitaltube display ensures display effect under long-distance and strong light.5. Power supply input has reverse connect protection function andself-recovery fuse protection function,6. The signal output has lightning protection, anti-ESD protection andanti-interference protection.Specification:Power SupplyVoltage: DC 7-30VPower SupplyCurrent: ≥150mAOutputCurrent: 4-20mAShellColor: GreySize:Approx. 7*4*5cm / 2.75*1.57*1.97inPackageWeight: Approx. 58g/2.0ozPackage list:1 * CurrentSignal GeneratorNote: Please allow slight error due to manual measurement.Thanks for your understanding.
