The Arduino Motor Shield is based on the L298 (datasheet), which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the current absorption of each motor, among other features. The shield is TinkerKit compatible, which means you can quickly create projects by plugging TinkerKit modules to the board. The Arduino Motor Shield must be powered only by an external power supply. Because the L298 IC mounted on the shield has two separate power units, one for the logic and one for the motor supply driver.The current draw for the motor supply is often than the USB can give. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the Arduino's board power jack on which the motor shield is mounted or by connecting the wires that lead the power supply to the Vin and GND screw terminals, taking care to respect the polarities. To avoid possible damage to the Arduino board on which the shield is mounted, we reccomend using an external power supply that provides a voltage between 7 and 12V. If your motor require more than 9V we recommend that you separate the power lines of the shield and the Arduino board on which the shield is mounted. This is possible by cutting the "Vin Connect" jumper placed on the back side of the shield. The absolute limit for the Vin at the screw terminals is 18V. The power pins are as follows: Vin on the screw terminal block, is the input voltage to the motor connected to the shield. An external power supply connected to this pin also provide power to the Arduino board on which is mounted. By cutting the "Vin Connect" jumper you make this a dedicated power line for the motor. GND Ground on the screw terminal block.

John asked Do SSRs with DC inputs typically function with both sinking and sourcing input configurations?
I've been looking at various SSR datasheets and I do not see anything about the inputs being sinking or sourcing. Do they work in both configurations? Are they usually designed to be one? Thanks!
And got the following answer:
Source: the currents direction goes from the IC input to the driver. Sink: the current direction comes from the driver to the IC input. Look at a typical DC Solid State Relay: http://denethor.wlu.ca/pc300/triacs/ssrtec.pdf As you see, it has a photo transistor input. That means a diode. That means conventional input current flows from positive to negative, in other words, from the driver to the IC input. That means, by the above definitions, it functions as a current sink. .
The relay driver ic function very nicely with distinctive applications that happen to be distinct to power distribution and protection. The relays come with wide adjustment ranges with a scale that may be easy to read either in 3 or 4 digits based on the model. These relay driver ic aid in escalating the flexibility from the applications, decrease the general energy and upkeep costs. You will discover relays that are used for general purposes which are available in reputable styles with rapid replacement possibilities. And there are actually models which are applied for industrial applications and heavier duty applications that operate on big loads. These products are made to meet the lifetime industrial handle wants with the applications.
Their latest products will be the Time counter, Timer Delay, relay driver ic, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and various other individuals. The website offers a detailed description of every single model in many categories of relay driver ic couplings and sensors. These goods are really beneficial for high-risk applications. The relay driver ic are also offered with features like many timing ranges and functions. The corporation is at present on the lookout for agents and dealers who can market and sell their factory created items. They’re constantly on a lookout for creating new and more dependable products determined by the wants and specifications on the industry.
