About AITIAO 3Pcs 5V 4 Channel Relay Shield Four Channel
Description: 1. The 5V Quad Relay Shield Module is a small current signal control power equipment commonly used electronic module; 2. Enabling high-power single-chip control devices are widely used in SCM system to make smart home project; 3. And can be directly plugged into the compatible the use of various types of motherboards, eliminating the patch cable troubles. 5V 4 Channel Relay Module 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) 6. Special Note: When using the board connected to it, because USB interface is extremely high, should avoid green terminals are shorted its shell. Specification: 1. Relay: Sky- 5V DC relay , model HJR-4102-L-5V, which Relay1 behalf of the 1st relay , the other and so on. 2. Power Interface : 5V DC power interface 3. Indicator: Four lights are red when the relay is driven high , the corresponding indicator will light up. 4. 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 Included: 3x 4 Channel 5V Relay Shield Module
