Portable Signal Generator 4~20mA Constant Current Analog Simulator Adjusting Module with Led Display for Inverter Contro

Features Output Impedance Matching of 4 20mA Current Generator The output source impendence should meet the following needs According to the formula I U R Current Voltage impedance the voltage of your power supply divided by the signal impedance is the max current that generated by the signal receiving terminal Besides there is impedance with this current generator so the formula should be the voltage of power supply the signal impedance of the device the impedance of the current generator output constant currentSince the voltage range of power supply of this product is 4 35V if the practical voltage of the power supply is low and the impedance of the device is high the product cannot provide enough constant curren Specification Power Supply 4 35VMeasuring Range 4 20mAWhen the power supply is 24V the signal impedance cannot be more than 1000ohm When the power supply is 12V the signal impedance cannot be more than 500ohm When the power supply is 5V the signal impedance cannot be more than 200ohm If the signal impedance is higher than the above parameters you can increase the voltage of power supply or decrease the signal impedance to solve the current shortage of the constant current source Please note that the voltage of the power supply cannot be higher than 28V WIDE APPLICATION Our signal simulator can be used in various areas signal generator valve adjustment frequency converter controlling PLC testing panel testing LED testing simulating the
