It is a 8 channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.

It is also able to control various appliances and other equipments with large current.

Relay output maximum contact is AC240V 10A and DC30V 10A.

HIGH level trigger

Standard interface can be directly connected with microcontrollers.

The working status indicator lights are conducive to the safe use.

Widely used for all MCU control, industrial sector, PLC control, smart home control.
