16 Channel Optocoupler Relay Module [12V] [10A]

Description: 
This relay module is 12V active low and each one needs 15-20mA driver current. It uses two 8-channel arrays chip to control the 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 equipment with a large current. Its maximum output contact is AC250V 10A and DC30V 10A. It has a standard interface that can be directly connected with microcontrollers. The working status indicator lights are conducive to the safe use and are widely used for all MCU control, industrial sector, PLC control, smart home control. It uses the industry’s top-quality isolation optocouplers, strong anti-jamming ability and stable performance.
The LM2596S buck chip in this relay module shows a slight fever which is a normal phenomenon as relays, long working hours have normal fever characteristics. 4 relay load power to give leave some margin, should avoid high power (about 2000W) and long working environment, there will be some impact on the life of the product. Each relay common terminal “COM” is independent and access to different signals. All interfaces can be directly connected through the terminal leads. The plate load power module doesn’t need an external power supply. It supports all SCM Drive.
