Specification:
Features: Input power is DC 3.3-30V, recommended power supply is 12-24VDC. Input power supply, product can generate 4-20mA current output by manual adjusting potentiometer, used for current analog quantity 4-20mA output. Output current can be constant automatically at setting value according to adjustment; it can also be used as a constant current source of which the maximum output current should not exceed 20mA. Universal power supply of module, can be used for PLC, frequency converter, servo. Module power consumption current is less than 30mA, supports for general equipment. Specifications: Type: Current generator Model: 4-20mA Potentiometer Installation Hold Diameter: 10mm Size(L*W*H): 73*54*30mm/2.9*2.1*1.2in Hole Spacing: 61mm/2.4in    Suitable Screws: M3 (NOT included) Weight: 74g(approx.) Wiring: 3-32V: DC power supply positive GND(left): Power supply negative   GND(right): 4-20mA output current negative 4-20mA-OUT: 4-20mA output current positive Potentiometer: Adjust output range of 4-20mA, clockwise to increase, counterclockwise to reduce Instruction: About Output Impedance Matching: Output signal resistance must meet the following requirements In this way, current generator still has some resistance. Thus concludes to a formula: Signal matching requirements is given below: For 24V power supply, signal resistance shall not be greater than 1000 ohms. For 12V power supply, signal resistance shall not be greater than 500 ohms. For 5V power supply, signal resistance shall not be greater than 200 ohms. Package Includes: 1 x Signal Generator
