Features :

1. 5V 16-Channel Relay Module with AC contact capacity of 10A 250V and optocoupler protection.
2. Onboard power supply module does not need an external power supply. I / O port driver is active low.
3. The module can be used as a microcontroller development board module and also as appliance control, PLC extended output.
4. It is using the industry’s top -quality isolation optocouplers, strong anti-jamming ability, stable performance.
5. The 1-16 road can be any full on/off or any road.
6. Each relay common terminal “COM” are independent, user-friendly access to different signals, each relay are normally closed and normally open with the port.
7. Each relay is equipped with motion lights.
8. All interfaces can be directly connected through the terminal leads, very convenient.
