Features 4 Digit Display: The signal generator has 4 different types of digital display with 2 decimal points. You can press the mode button to switch the display mode between voltage and current, or you can switch the 0 to 100 percent or 0‑50Hz display according to the instructions. Multiple Power Supply Modes: The function generator can supply power through various modes, Each mode can make the signal generator work. Application: The signal source generator can be used for PLC and panel debugging, equipment testing, frequency converter, flow valve, servo motor speed regulation, dimming, etc. And the fenerator is small and portable. Output Range: The output range is passive or active 4‑20mA, and the voltage output can be accurate to 0.01V. The output range and accuracy can be programmed and adjusted. Short Circuit Protection: The output has short circuit protection, and the power supply has reverse connection protection, which is safe to use. Users can set 9 fast signal output points, which is more convenient for debugging. Features: 1, the test output is normal, you can use a multimeter (DC current file) short "4-20mA output" terminal value and the comparison shows that the multimeter readings are the same 2, the product can be used: signal sources, regulating valves, control, test instrumentation, light emitting diode test, the inverter output analog transmitter 3, the header housing, easy to install, hole size: 76mm * 40mm. The overall size of 80mm * 42mm Packing include:1 x DC 12V 24V 4-20mA Signal Source Signal Generator Constant Current Source 0.01mA Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
