Feature:
1. Signal Output: Connect to power supply to send 4-20MA industry standard constant current source control signal output.
2. Safer Working: Designed to have anti reverse protection, self recovery fuse protection, electrostatic protection, etc.
3. Broad Utility: Enables application on inverter control, PLC debugging, valve adjustment, instrument testing and so on.
4. Clear Display: Digital display allows for a clear view, while the multiturn potentiometer makes the adjustment easier.
5. Simple Wiring: 5.08MM pitch male and female sockets are used for wiring, and a space is reserved in the middle.
How to Use:
1. The input voltage of the power supply is 7?30V. Pay attention to matching the output load. The larger the internal resistance of the load, the higher the power supply voltage should be selected for matching. The specific matching calculation requires a lot of parameters to be calculated. According to experience, any voltage of 9V, 12V and 24V can be used for power supply. If you find that the current is adjusted to the maximum and is not enough to 20MA, you can solve the signal matching can be solved by gradually increasing the voltage. In general industrial occasion, 24V power supply can be selected.
2. Power Supply Current: In order to e
