As a matter of fact, it controls the on and off of the solenoid valve. Take the DCS to control switching of pneumatic valve is very easy. Does this mean there are two cable lines? If there is the valve position switch, how will the wiring become? Does the valve position switch require independent power supply? Then, how much cable is required in total? The DCS outputs a DO signal and requires one 220V power supply cable. Take the 220V AC pneumatic valve for example. Either in terms of 24 V DC or in terms of 220 V AC, there are two wires which can lead to generation of magnetism for the coil (which is the power supply wire), and the other one is for ground connection. The solenoid valve on the pneumatic valve is generally three-wired. Is it that the solenoid valve on the pneumatic stop valve can be two-wired, three-wired or four-wired? Here are some problems for your reference.ġ. Although the wiring of solenoid valve is simple, but poeple still encouter problems when wiring the solenoid valve to other devices.
