Watch the latest video for this 5v relay.
It can be used to control various appliances and equipment with large current.
It can be used to control various appliances and equipment with large current.
Standard interface that can be controlled directly by microcontroller.
It can act as switch if the circuit and the load circuit have different supply voltage.
Welcome guest sign in register.
It has three pins the vcc gnd and signal.
The six pins on the left side of the relay module connect high voltage and the pins on the right side connect the component that requires low voltage the arduino pins.
5v 8 channel relay module.
Status led indicator included.
Relays are most commonly used switching device in electronics.
4 channel 5v optical isolated relay module this is a low level 5v 4 channel relay interface board and each channel needs a 15 20ma driver current.
If the relay can t open or close maybe you need remove the r4 and use the usb to ttl module s vcc pin connect to relay module s 5v pin.
A00100a1 closed relay command format must be hex with serial debugging software on the pc to control the relay.
It is commonly use if the load circuit is ac.
Before we proceed with the circuit to drive the relay we have to consider two important parameter of the relay.
