12V 2 Channel Relay Module

Overview

A 2-channel relay module with 12V control logic, letting a microcontroller switch two high-power AC or DC loads independently.

Key Specs

Features

• Screw terminals for COM/NO/NC per relay
• Opto-isolated inputs on most modules

Compatible With

Any MCU outputting 12V-compatible logic, or via a level-shifter/transistor from a lower-voltage board

Use Cases

• Switching two independent AC appliances or DC loads

FAQ

What's the max switching load? Check the relay's printed rating (commonly 10A @ 250VAC) — never exceed it.
