220v/24v Solenoid valve coil resistance
The resistance value of the 24v solenoid valve coil is about 20 ohms to 200 ohms. The resistance values of different models from different manufacturers are not necessarily the same. If the measured resistance value is not within these ranges, the coil may There is a problem.
The resistance value of the 220v solenoid valve coil is approximately 6/220(Ω), Solenoid ValveIt also depends on the power. The ones used on 4Kg pressure pipes and 10Kg pressure pipes must be different, right, but generally it must be greater than 300 ohms. The 0.2 ohm ones must be broken. The 1.16K ohm ones are not sure. Regarding the screws of the electrical contact pressure gauge, except for the connecting wire fixing screws.
What is the general resistance of the solenoid valve coil< /strong>
Depending on the power of the coil, the resistance value is different, which is related to the quality and power. The power of good quality is generally smaller, about 4W, which reduces the heat. R=U2/P, the square of the voltage divided by the power, look at the nameplate to know.
The size of the resistor will affect the characteristics of its control loop. For example, if the resistance is increased, the power supply remains unchanged, but the characteristics of the controlled load change, affecting the working characteristics of the load. Mainly reflected in voltage, current, etc., the current is large, the opening time is short, the current is small, it can be opened, but the time is slow. Detailed analysis requires the specific structure, Electromagnetic theoryTheoretical analysis. Purpose, the smaller the resistance value, the better. If you want to add a delay, you can add a delay circuit to the loop.
