The wires of an ssr are smaller and of a higher gauge. The elecrow relay shield has the following points to ensure its usage.
Using A Transistor Instead Of A Relay To Control A Dc Motor
Why use a relay instead of a switch. Yes it is so easy to use a relay. But it is theoretical we need to notice something in actual usage. One reason you might want to use a relay is if the circuit being controlled needs to be electrically isolated rather than just being off. With a switch youll additionally need to run thicker wires enough to deal with 30 40 amps since it requires more voltage than a transfer. A reliable relays is the most important and as the copper width and weight will impacts the max current that can be flowed in the circuit the width of the layout should meet the current requirements. Relays are distinct from transistors in a few key ways.
A correctly wired relay will provide the shortest electrical path ie. Relays are a time tested technology and they physically switch contacts as if you were throwing a switch yourself. Electronic switches do not completely isolate and will allow a small leakage current to flow when they are off. This is useful because the magnet uses a very small amount of electricity usually less than 1 amp to move the big clunky contact that can handle a big current usually 30 40 amps which is more than any reasonably sized switch. Transfers are littler and more affordable than switches. Using relays allows you to control a number of devices with a single switch a master ignition switch on a race car.
Shortest wire length between the battery and. So a relay is a switch that is turned on or off by electricity a small electro magnet moves a contact inside. The central point is accommodation wellbeing and cost. Here are five of their biggest differences. Here are some reasons why relays are better than switches. Christian none 82117 1243 am.
Reliable relays and layout. Why use a relay instead of a switch. Typically they use an electromagnet reed switch to allow a small electric signal to switch much higher voltages. Using relays instead of switches are much saferrelays can be operated in very low voltage but can handle high voltages and much saferswitches are only manual operated easily.
