This is a 5V 2-Channel Relay IOT interface module, for controlling various appliances, It can be controlled directly by microcontroller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430) TTL logic.

Description:

• 5V 2-Channel Relay interface board, and each one needs 15-20mA driver current.
• Optical isolation on each channel.
• Standard interface that can be controlled directly by microcontroller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430) TTL logic.
• Equipped with high-current relay: AC 220-240V 10A / DC 30V 10A.
• Indication LEDs for relay output status.
• Equipped with screw holes for easy installation.
