8-Channel 5V Relay Module opto-isolated

This is a 5V 8-Channel Relay interface board, Be able to control various appliances and other equipment with large current. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).

• 5V 8-Channel Relay interface board and each one needs 15-20mA Driver Current
• Equipped with high-current relay, AC250V 10A ; DC30V 10A 
• Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)   
• Indication LED’s for Relay output status

DESCRIPTION

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 a lot of 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 makes it extremely convenient for prototyping.
• LED indicates its working status. Red refers to errors.
• 3 terminals per SPDT relay.
