4-Channel 30A Relay Module - Optocoupler Isolation High/Low Trigger - DC 12V D1F6

Okay, electronics folks, here's a solid relay module for your projects.

It's a 4-channel board, meaning you can control four separate high-power devices with it.

Each relay can handle up to 30 amps at 30V DC or 250V AC, so it's pretty beefy.

It features optocoupler isolation, which helps protect your sensitive control circuits (like an Arduino or Raspberry Pi) from voltage spikes.

You can set it for either high-level or low-level trigger, making it super flexible for different setups.

It runs on a standard DC 12V supply, with a quiescent current of just 5mA.

The module itself measures about 100 x 83 x 20mm and weighs 172g.

It's a generic unbranded board, but it's packed with features and ready to work.

Whether you're automating lights, controlling motors, or building a home automation system, this relay module is a reliable and affordable choice.

Just give it a signal, and it switches the power.

Simple as that.
