Relay Shield (ie 5V Quad lss module) is a small current power signal control equipment commonly used electronic module, which allows single-chip high-power control devices are widely used in the SCM system to make project smart home; and the use of various types of motherboards can be inserted directly into the Arduino, eliminating patch cable problems.

Module features are as follows:
1. Standard Arduino Shield interfaces and shape
2. Can continue to stack other Arduino expansion boards
3. 3 M3 screw positioning holes for easy installation
4. High Drive (5V or 3.3V) normally open contact closure
5. Onboard relay indicator (red)

Relay Shield Interface: (the last picture show)
Relay: sky- 5V DC relay , model HJR-4102-L-5V, which Relay1 behalf of the 1st relay , the other and so on.
Power Interface : 5V DC power interface
Indicator: four lights are red when the relay is driven high , the corresponding indicator will light up .
Relay Terminals: Terminal high-power , high-current high voltage can be connected to the device . The 1st foot ( i.e. NOx) is a normally open pin , NCx pin is normally closed , COMx is common, i.e., when the relay is not driven , NOx and COMx open between two pins , NCx and COMx connection ; When the relay (x) control signal pin is high drive relays , NOx and COMx connection open between NCx and COMx.

Special Note: When using the Arduino UNO board connected to it, perches the UNO USB interface is extremely high, should avoid green terminals are shorting its shell.

Package Included:
1 x four-channel Relay Shield
