Description:Relay Shield (ie 5V Quad Relay Module) is a small current signal control power equipment commonly used electronic module, enabling high-power single-chip control devices are widely used in SCM system to make smart home project; and can be directly plugged into the compatible the use of various types of motherboards, eliminating the patch cable troubles.Module features are as follows:◆Standard For Shield interfaces and shape◆Can continue to stack other For expansion boards◆3 M3 screw positioning holes for easy installation◆High Drive (5V or 3.3V) normally open contact closure◆Onboard relay indicator (red)◆Special Note: When using the For UNO board connected to it, because UNO USB interface is extremely high, should avoid green terminals are shorted its shell.Relay Shield Interface:◆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.Package includes:1 x 4 Channel Relay Module
