AITIAO 3Pcs 4 Channel 5V Relay Shield Module Four Channel Relay Control Board Relay Expansion Board for PIC AVR DSP ARM MCU

Brand: AITIAO

Features:

• 5V 4 channel relay shield can continue to stack other for expansion boards.
• Standard interface that can be controlled directly by microcontroller
• Onboard relay indicator: Four lights are red when the relay is driven high , the corresponding indicator will light up .
• High Drive (5V or 3.3V) normally open contact closure;3 M3 screw positioning holes for easy installation.
• Special Note: When using the board connected to it, because USB interface is extremely high, should avoid green terminals are shorted its shell.

Details: 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:
3 * 4 Channel 5V Relay Shield Module
