Two Channel 5V Relay Module With Opto Isolated High Low Level Trigger For Safe Easy Plug And Play Control Of AC And DC Loads Ideal For Microcontrollers And Home Automation Projects

Single 2-Channel 5V Relay Module with Opto Isolation
✔️ 2-channel 5V logic, opto-isolated relays, high/low trigger

The two-channel 5V relay module is a compact control interface that lets microcontrollers safely switch AC and DC loads. It's ideal for home automation, robotics, and embedded projects, offering opto-isolation to protect your control circuitry and easy 5V logic interfacing.

✅ Dual-channel 5V relay module with opto isolation and high/low triggering.
✅ NO/COM/NC outputs handle AC 250V/10A or DC 30V/10A.
✅ Trigger current around 5 mA; TTL-style gate circuit supports 5V logic.
✅ The relay will not operate if the control line is disconnected.
✅ Size 51 x 46 x 19 mm; weight ~30 g; mounting holes on both sides (3.1 mm).
