Arduino 5V 16 way relay module optocoupler isolation low level trigger

• This 5V 16-Channel Relay interface board can regulate a wide range of appliances and other high-current devices.
• Micro-controllers (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) can be used to directly control it.
• A 5V 16-Channel Relay interface board requires 50–60mA of driver current per relay.
• Equipped with a DC30V 10A high-current relay and an AC250V 10A relay.
• Regular interface that a microcontroller may directly operate.
• LEDs that indicate the state of the relay output.
• High Level Trigger.
