5V 16 Channel Low Level Relay Module with Light Coupling LM2576 Power Supply

5V relay with AC contact capacity of 10A 250V and optocoupler protection.
Onboard power supply module does not need an external power supply. I / O port driver is active low.
The module can be used as a microcontroller development board module and also as appliance control, PLC extended output.
It is using the industry’s top -quality isolation optocouplers, strong anti-jamming ability, stable performance.
The 1-16 road can be any full on/off or any road.
All interfaces can be directly connected through the terminal leads, very convenient.
