It is an 8 Channel Isolated 28V 10A Relay Module, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other types of equipment with large current. Relay output maximum contact is AC250V 10A and DC 28V 10A. One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use.

This Relay is used for wide variety of AC & DC applications like Home Automation configured, Solenoids, Motors, lights, fans, heavy load device, home appliances & controlling higher current loads from microcontroller development board.

Design and Operation:-

When an electric current is passed through the coil it generates a magnetic field that activates the armature and the consequent movement of the movable contact either makes or breaks (depending upon construction) a connection with a fixed contact. If the set of contacts was closed when the relay was de-energized, then the movement opens the contacts and breaks the connection, and vice versa if the contacts were open. When the current to the coil is switched off, the armature is returned by a force, approximately half as strong as the magnetic force, to its relaxed position. Usually this force is provided by a spring, but gravity is also used commonly in industrial motor starters. Most relays are manufactured to operate quickly. In a low-voltage application this reduces noise; in a high voltage or current application it reduces arcing. When the coil is energized with direct current, a diode is often placed across the coil to dissipate the energy from the collapsing magnetic field at deactivation, which would otherwise generate a voltage spike dangerous to semiconductor circuit components. Some automotive relays include a diode inside the relay case. Alternatively, a contact protection network consisting of a capacitor and resistor in series (snubber circuit) may absorb the surge. If the coil is designed to be energized with alternating (AC), a small copper "shading ring" can be crimped to the end of the solenoid, creating a small out-of-phase current which increases the minimum pull on the armature during the AC cycle. 

Relay can control any devices just like a switch contact. Its contact is isolated from the driven circuit. 

It is important that microcontroller share ground with relay board along with other control signals else it will not able to control relay.
