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.
