yahoo2 asked what is solenoid and presure switch how they work?
sending my problem. You have a flood defense system When an input is made for more than 5 seconds start a warning siren and lamp for 30seconds. After this time delay a solenoid will operate to lift a barrier. Once the barrier is lifted to its closed position a air seal inflates by another solenoid. This seal is controlled by a pressure switch. The solenoid inflates the seal until the pressure switch makes. If the pressure switch does not make within 10 seconds of the solenoid energising then sound an alarm. This alarm can be cancelled by an operator. If the air pressure drops the seal solenoid can re-energise until the pressure switch makes again. When the signal for the barrier lift goes off the barrier stays in position until an operator presses a reset button then the seal can deflate and the barrier can lower. The barrier has two solenoids, one for lift and one for lower. The seal inflate has two as well one to inflate and re-flate and the other to deflate. with the help of the above mentioned text i am supposed to write a PLC programm
And got the following answer:
pressure switch A Pressure switch is a form of switch that makes electrical contact when a certain set pressure has been reached on its input. This is used to provide on/off switching from a pneumatic or hydraulic source. The switch may be designed to make contact either on pressure rise or on pressure fall. solenoid switch In engineering, the term solenoid may also refer to a variety of transducer devices that convert energy into linear motion. The term is also often used to refer to a solenoid valve, which is an integrated device containing an electromechanical solenoid which actuates either a pneumatic or hydraulic valve, or a solenoid switch, which is a specific type of relay that internally uses an electromechanical solenoid to operate an electrical switch; for example, an automobile starter solenoid, or a linear solenoid, which is an electromechanical solenoid. and i am really sorry that in this sheet I cant able to draw ladder diagram
The pneumatic time delay relay operate exceptionally well with various applications which are specific to power distribution and protection. The relays come with wide adjustment ranges with a scale that is definitely easy to read either in three or 4 digits in line with the model. These pneumatic time delay relay aid in increasing the flexibility on the applications, decrease the overall power and upkeep charges. You will find relays that are utilised for common purposes which come in dependable designs with rapid replacement choices. And you will discover models that are utilised for industrial applications and heavier duty applications that function on significant loads. These merchandise are made to meet the lifetime industrial manage requirements of the applications.
