4-20MA Signal Generator For Inverter Control PLC Debugging Instrument Testing Analog Transmitter Output

Feature 1 Wide power supply voltage range the input power supply is DC 5 28V DC and the recommended power supply is 12 24V DC 2 Perfect protection function with input voltage reverse connection protection the instrument will not work if the power supply is reversed and it will not burn out due to reverse connection 3 Standard current output range 4 20MA current output can be generated by manually adjusting the potentiometer on the product which is used for the occasions where the current analog output is 4 20MA 4 The current adjustment is very stable the wire wound potentiometer is used to adjust the current and the adjustment is stable which avoids the faults such as the sudden change of resistance generated by the general carbon film potentiometer 5 With an ammeter head the display is accurate 6 With a scale dial you can quickly locate and identify the operating status of the equipment according to the scale 7 The current output value can be fixed the output current can be automatically constant at the set point according to the customer s adjustment and can also be used as a constant current source When used as a constant current source the maximum current output does not exceed 20MA 8 The golden ratio of the body is easy to hold and turns work into a pleasure 9 To test whether the output is normal you can use a multimeter DC current gear to short circuit the current positive and current negative terminals and compare whether the dis
