AITIAO 3Pcs 4 Channel 5V Relay Shield Module for UNO R3 Relay Shield,Four Channel Relay Control Board Relay Expansion Board for Arduino PIC AVR DSP ARM MCU UNO R3 Mega 2560
Description
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 shape2. Can continue to stack other For expansion boards3. 3 M3 screw positioning holes for easy installation4. High Drive (5V or 3.3V) normally open contact closure5. Onboard relay indicator (red)6. 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.Specification: Relay Shield Interface: As the picture shows 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 interface3. 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 for UNO R3
