5V One Channel Relay Module With Opto Isolation And High Low Level Trigger, Two Pack, 10A AC 250V And 10A DC 30V Load, Fault Tolerant Design, Strong Driving Capability, Safe Plug And Play For Microcontrollers And Home Automation
✔️ 5V input, opto-isolated, fault-tolerant, supports 10A loads
The module is a compact 5V, single-channel relay board designed for microcontrollers and home automation. It uses a genuine optocoupler for isolation, provides NO/COM/NC contacts, and includes a jumper to switch between high or low level triggering. Module size: 50mm x 26mm x 18.5mm. Pack size: 2 units, included as a two-pack.
✅ 5V control, opto-isolated driver for safe MCU interfacing
✅ Maximum load: AC 250V 10A, DC 30V 10A
✅ Fault-tolerant design prevents relay movement if the control line is broken
✅ Direct terminal leads for easy plug-and-play with microcontrollers
✅ Jumper selectable high or low level trigger
💡 What is a 5V relay module with opto isolation used for in microcontroller and home automation projects?
This handy device lets you safely switch higher voltage circuits from a low-voltage controller.
- galvanic isolation protects the control circuit from high voltages- handles AC loads up to 250V and DC loads up to 30V, 10A
- jumper selects high or low level trigger for flexible control
- fault-tolerant design prevents unintended relay operation if input line is broken
