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 dc timer relay operate exceptionally well with unique applications which can be particular to power distribution and protection. The relays include wide adjustment ranges having a scale that is definitely simple to study either in three or 4 digits in accordance with the model. These dc timer relay support in increasing the flexibility on the applications, minimize the all round energy and maintenance fees. You will discover relays which are utilized for common purposes which are available in reliable styles with fast replacement selections. And you’ll find models which are applied for industrial applications and heavier duty applications that perform on massive loads. These goods are produced to meet the lifetime industrial control desires on the applications.
Their latest merchandise will be the Time counter, Timer Delay, dc timer relay, Swift Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and several other folks. The site presents a detailed description of each and every model in many categories of dc timer relay couplings and sensors. These items are really beneficial for high-risk applications. The dc timer relay are also accessible with attributes like a number of timing ranges and functions. The firm is at the moment trying to find agents and dealers who can market and sell their factory produced merchandise. They’re often on a lookout for establishing new and more trustworthy solutions depending on the desires and requirements of your industry.
