16-Channel 5V Relay Shield Module with Optocoupler Low Level Triger for Arduino Mega

Overview:

• This relay module is 5V active low, and each one needs 15-20mA driver current.
• Uses two 8-channel ULN2803APG darlington arrays chip to control relay module.
• It is a 16-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 AC250V 10A and DC30V 10A.
• 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.
