Product Information

- 5V 4 Channel Relay Shield for Arduino UNO R3
- UNO R3 Relay Shield with Four Channel Relay
- With Indication LEDs for Relay output status
- Standard interface that can be controlled directly by microcontroller

Description:
This 5V 4 Relay Shield 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; and can be directly plugged into the compatible the use of various types of motherboards, eliminating the patch cable troubles.

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)
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 Interfaces:
Relay: 5V DC relay, HJR-4102-L-5V, the Relay1 is be behalf of the 1st relay, the same for others.
Power Interface: 5V DC Power
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.

Package Included:
1 * 5V 4 Channel Relay Shield (Without Arduino boards)
