8 Channel Relay Board 5V With Optocoupler

8 Channel Relay Board 5V – This is an 8-channel relay board that operates on 5V. They can be used directly to control 240V power appliance from most of the microcontrollers and other control system circuits. Perfect for switching 240V appliances like lights, fans, etc.

The board has a high-quality relay, which can handle a maximum of 10A @ 250V or 15A @ 125V AC. Each Relay has three connections – Common – C, Normally Open-NO, Normally Closed-NC brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board.

Description

8 Channel Relay Board 5V – It is an 8 Channel Isolated 5V 10A Relay Module optocoupler, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other types of equipment with a large current. Relay output maximum contact is AC250V 10A and DC30V 10A. One can connect a microcontroller with a standard interface directly to it. Red working status indicator lights are conducive to safe use. The 8 Channel Isolated 5V 10A Relay Module optocoupler has a wide range of applications such as all MCU control, industrial sector, PLC control, and smart home control. So, ready to get switching on your Raspberry Pi?! This neat relay module features 8 x 12V relays rated at 10A/250V each. It is designed to switch up to 4 high currents (10A) or high voltage (250V) loads with the help of a microcontroller!

Each relay can individually switch to on/off state. It only requires a voltage of approx 1.0V to switch the inputs on but can handle input voltages up to 12V. This makes it ideal for 3.3V, 5V & 12V devices.

Note: On the high level and low level-triggered mode, friends who do not understand, have a look

A high-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered away;
Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as the signal input terminal and the GND negative electrode short circuit triggered away 1-channel relay module connection.
