AITRIP 2PCS 4 Channel 5v Relay Shield Module for Arduino UNO R3 Relay Shield Interface 4 Four Channel for PIC AVR DSP ARM MCU Arduino UNO R3
Description
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)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: (the last picture show)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 interfaceIndicator: 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 included:2x 4 channel 5v relay shield module
Features:
- 5V 4 Channel Relay Shield for Arduino UNO R3
