Features:
1.Standard For Shield interfaces and shape.
2.Can continue to stack other For 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).
Descriptions:
1.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.
2.Can be directly plugged into the compatible the use of various types of motherboards, eliminating the patch cable troubles.
Specification:
Co... 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 For UNO board connected to it, because UNO USB interface is extremely high
