UMER asked How to change the direction of dc current in a circuit?

Is there any way that i can automatically change the direction of current in a DC circuit after a predefined time. that means i will have to use H bridge is this device ready made available or i have to make it also cant understand how to use electronic timer so it reversed direction after lets say 20 secs I am just using a simple motor for which i want to change its direction automatically after 20 sec is there any IC available to do that

And got the following answer:

The suuply is reversed by a double pole changeover switch, one changeover for each leg. For automatic operation, this switch can be a relay, that is in turn operated by a timer device. If there is significant power involved it is important to make sure the contacts break well before the other pole makes in the changeover. That is, a dead zone. With motors, you might need to stop the motor before reversing it. A solid state switch that does the same is a H bridge. The circuit is wired like the letter H with electronic switches on each leg (4 of them) and the load on the horizontal of the H. One diagonal pair is on for one direction, and the other pair for the other direction. This is commonly used for reversing DC motors. There also needs to be a dead zone between switching one pair off (so all 4 are off) then switching on the other pair. A timer can be mechanical or electronic. Mechanical timers have a motor driving a disk with pegs that operate the switch. Electronic timers for times longer than a few seconds are often a counter that counts the frequency of an oscillator etc, timing out when a specific count is reached. For shorter times from a few microseconds to a few seconds a 555 timer device might do. The timer may be triggered by some event (the power came on, something pressed a button) or even by itself so the reversal is repeated over and over in a loop. This needs specific circuitry for the application. Look up relays, H bridge, 555 timer circuits to learn more.

The solid state relay circuits function extremely effectively with various applications which are specific to power distribution and protection. The relays include wide adjustment ranges having a scale that is easy to read either in three or four digits as outlined by the model. These solid state relay circuits assist in escalating the flexibility on the applications, minimize the overall power and maintenance fees. There are relays that are utilised for common purposes which come in reputable designs with fast replacement options. And you will find models which are made use of for industrial applications and heavier duty applications that perform on large loads. These solutions are made to meet the lifetime industrial control requirements with the applications.
Their most current solutions will be the Time counter, Timer Delay, solid state relay circuits, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and various other individuals. The internet site offers a detailed description of each and every model in many categories of solid state relay circuits couplings and sensors. These products are particularly helpful for high-risk applications. The solid state relay circuits are also readily available with options like a number of timing ranges and functions. The enterprise is at present searching for agents and dealers who can promote and sell their factory produced goods. They’re often on a lookout for establishing new and much more trustworthy products depending on the desires and requirements on the industry.
