DESCRIPTION

2 Channel 5V Relay Module (Discontinued)

5V 2-Channel Relay interface board; each relay requires 15-20mA Driver Current.
Equipped with high-current relay: AC250V 10A; DC30V 10A.
Standard interface that can be controlled directly by microcontrollers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic).
Indication LEDs for relay output status.
Activates on low level.

4 Channel 5V Relay Module

5V 4-Channel Relay interface board; each relay requires 15-20mA Driver Current.
Equipped with high-current relay: AC250V 10A; DC30V 10A.
Standard interface that can be controlled directly by microcontrollers (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic, active low).
Opto-isolated inputs.
Indication LEDs for relay output status.

8 Channel 5V Relay Module

A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits.

This 8-channel 5V relay has both optical and magnetic isolation, providing protection to the inputs from electrical faults on the outputs.
Works well with both 3.3V and 5V logic (Raspberry Pi, Arduino, Teensy), requiring little current drive.
Breadboard friendly, using female/male dupont connectors for convenient prototyping.
LED indicates its working status; red indicates errors.
Three terminals per SPDT relay.

All of these features make the SainSmart relay a great component for automation projects.
