Features Easy to use: The signal generator uses a knob to operate, easy to use, easy to connect, and immediately respond to the output after adjustment, without delay, to achieve stepless fine-tuning, especially the actual fineness of multi-loop (5*360) potentiometer adjustment can reach 0.01mA, Operate freely Output load impedance range: The signal source generator uses 12V DC power supply, output load impedance range is between 0-350 ohms; 24V DC power supply between 0-800 ohms, output load impedance range Whether the test output is normal: Whether the electronic instrument test output is normal, you can use a multimeter (DC current file) to short-circuit the "4-20mA output" terminal value and the comparison shows that the multimeter reading is consistent Multi-purpose signal generator: The signal source generator can be used for signal source, regulating valve, control, test instrument, light-emitting diode test, inverter output analog transmitter Size: The digital signal source generator adopts a header shell, which is easy to install. The opening size is 76mm*40mm, and the overall size is 80mm*42mm. Features: 1. The signal source generator is easy to use, easy to wire, knob operation, in response to the output immediately after adjustment, no delay 2. In order to achieve stepless fine adjustment, particularly multi-ring (5 * 360) potentiometer to adjust the actual fineness of up to 0.01mA, operate freely 3. The power supply voltage: 12V DC or 24V (tolerance ± 25%), Total power <1W. 4. 12V DC power supply, output load impedance range between 0-350 ohms; between 0-800 Ohm 24V DC power supply, output load impedance range 5.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 6. The digital signal source generator can be used: signal sources, regulating valves, control, test instrumentation, light emitting diode test, the inverter output analog transmitter 7. 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 Package List
