5V 4 Channel Relay With optocoupler Board Module
Each relay can individually switch on/off by an opto-isolated digital input, which can connect directly to a microcontroller output pin. This 5V 4 Channel Module Kit only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 5V. This makes it ideal for 1.0V to 5V devices.
5V 4 Channel Relay With optocoupler Board Module is also able to control various appliances and other types of equipment with a large current. Relay output maximum contact is AC250V 10A and DC5V 10A. One can connect a microcontroller with a standard interface directly to it. These Red working status indicator lights are conducive to safe use. It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.
