Various protection circuits are designed inner side, the output signal is pure, and the performance of the whole machine is stable and reliable. The product can be used for: inverter control, PLC debugging, valve adjustment, instrument test, light-emitting diode test, analog transmitter output, signal source generation, etc. Meter head housing, easy to installPower inputV+: Connect to the positive terminal of the power supplyV-: Connect to the negative terminal of the power supply (GND ground wire)Current outputC+: Positive terminal of output currentC-: output current negative terminal1. The power input voltage is 7-30V (5V power supply can be customized). Pay attention to matching with the output load. The greater the internal resistance of the load, the higher the power supply voltage must be used to match. The specific matching calculation needs to find out many parameters In order to calculate it, most users do not have such conditions or do not have relevant information on hand. According to experience, it can be solved like this: Generally, you can choose any voltage power supply of 9V/12V/24V. If you find that the maximum current is not enough to 20MA In the case of, you can gradually increase the supply voltage to solve the problem of signal matching. In general industrial occasion, 24V power supply is enough.2. Power supply current. In order to make sure the stability of the system, the power supply terminal of this product must have a current output capacity of at least 500MA.3. Output ripple coefficient <30MV.4.
