1 Channel Relay module, suitable for Arduino, Atmel, PIC, AVR, ARM, Raspberry Pi and more - 1 Channel Relay - Indicator LED - 5 Volt Operating voltage
1 channel relay
5 Volt Operating voltage
1 LED indicator
The 1 Channel Relay Module is ideal for Arduino, but to Arduino it is also suitable for other platforms where I / O ports can be set via software.
With all applications where you can use an I / O as an output, you run into the problem that you cannot switch a heavy load with that I / O, applying a relay is the right solution for that, especially if you want to switch loads. where many amperes are used such as a heavy motor that quickly consumes 5 amps.
If you do not want to use a mechanical switching element, then a mosfet is also suitable for use or possibly the use of a Solid State relay.
This 1 channel relay module controls the relay through an optocoupler, so the relay is as it were separated from your Arduino board or other controller unit
the module must therefore have its own power supply capable of supplying 5 volts DC.
In addition to the 1 channel relay module, there are also more extensive variants of these modules such as the 2 channel, 4 channel, 8 channel and even 16 channel. There is also a 6 channel version but we don't have this.
The 1 channel relay module contains a relay that we also sell separately, so you can possibly build your own 6 channel module. many hobbyists have done this and if you want to do this and look for a schedule then we will gladly help you with that.
