Does the dc24v solenoid valve have positive and negative poles? Can the positive and negative poles of the dc24v solenoid valve be connected casually?

dc24v solenoid valve Are there positive and negative poles

Question:The DC24V power supply of the SMC solenoid valve is a DC power supply. Negative pole, but in fact, when wiring the 24Vsolenoid valve on site, There is no distinction between positive and negative, and the solenoid valve can work normally even if it is connected to it. Why?

Answer:How to connect the SMC solenoid valve wiring when there is no positive or negative distinction? All the same, it is the Japanese SMC solenoid valve that is understood as an automatic switch in the square block after it is powered on. You can understand it this way. When there is current flowing through the coil, the direction of the N and S poles of the electromagnetic induction is determined;but for the armature, regardless of the N pole or the S pole, it will also generate attraction for it. Therefore, there are some above Standard AC/DC 24V power supply;when using DC24V, there is no need to consider positive and negative. The internal circuit is protected against positive and negative, regardless of positive and negative.

Question:Are all brands of DC24V power supply voltage solenoid valves regardless of positive and negative poles, or are there no distinctions between individual brands?

Answer:Only SMC’s DC solenoid valve does not need to consider polarity. No matter how you connect it, it will not affect the use and instructions.

1. Because it is an electromagnet, there is no direction. .

2. It is just because Japanese SMC solenoid valves are used The whole bridge is connected, and the indicator light wiring is arbitrary.

dc24v solenoid valve positive and negative Not picked up casually

< span style="font-size: 16px;">Terminals B and D are connected to the positive pole, and terminals A and C are connected to the negative pole.

Ordinary DC24V solenoid valve does not have positive and negative , all can work normally. But not all DC24V solenoid valves can be divided into positive and negative. This mainly determines the circuit inside the coil, because some solenoid valves are not completely coils, but also have part of the electronic circuit inside. Therefore, if you use them, it is still It's better to connect according to the instructions.

There is a red or white light-emitting diode on the solenoid valve connected in series with a resistor and connected to both ends of the coil. Generally, the positive connection is connected Solenoid ValveOn the "H" marked end (or the end connected to the resistor), connect the negative wire to the "L" marked end (or the end connected to the diode) on the solenoid valve. This will eliminate the possibility of the control loop being disconnected. The reverse self-induced electric potential produced by the electromagnetic coil.

The above isDoes the dc24v solenoid valve have positive and negative poles? Does the dc24v solenoid valve have positive and negative poles? Just pick up the introduction. If you want to know more about it, please log in to www.diancifa.cc.
