5V 10A 4-Channel Optocoupler Relay Module Board

It is 5V 10A 4-Channel Optocoupler Relay Module Board use in a wide range of microcontrollers such as Arduino, ESP8266, ESP32, Raspberry Pi and so on can control it. Arduino 4 relay module 5V is also able to control various appliances and other types of equipment with large current.

Relay output maximum contact is AC250V 10A and DC5V 10A. One can connect a microcontroller with standard interface directly to it. Red working status indicator lights are conducive to the safe use. It has a wide range of applications such as all MCU control, industrial sector, PLC control, smart home control.

This neat 5V 4 channel relay module features 4 x 5V relays rated at 10A/250V each. ESP32 relay board 4 channel is designed to switch up to 4 high current (10A) or high voltage (250V) loads with the help of microcontroller!

Each relay can individually switch on/off by an opto-isolated digital input, which that can connect directly to a microcontroller output pin. This 10A optocoupler relay board 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.
