Ten Pack 5V Relay Module With Optocoupler Isolation One Channel Switch Board High Or Low Level Trigger For Microcontrollers And DIY Projects 250V AC 10A DC 30V 10A Fault Tolerant Design And Terminal Wiring
✔️ 1-Channel 5V DC relay, 10A/250VAC, opto-isolated, jumper selection
This compact 5V relay module provides isolated control for microcontrollers and DIY projects. It interfaces cleanly with ARM, PIC, AVR, Raspberry Pi, CNC machines, and other hobby electronics, delivering reliable switching for small to medium loads.
✅ 1-channel 5V relay module with optocoupler isolation
✅ Coil voltage 5V DC; loads up to 250V AC / 10A or 30V DC / 10A
✅ Fault-tolerant design keeps relay from energizing if control line breaks
✅ Jumper selects high or low trigger for flexible interfacing
✅ Screw terminals for relay (NC, C, NO) and input (Coil+, Coil-, Trigger)
💡 What is a 5V relay module with optocoupler isolation used for in microcontroller projects?
This handy tool lets you switch higher-power devices safely from a low-voltage controller while protecting the control side from spikes and noise.
- High isolation keeps relay current from affecting the MCU or sensors
- Jumper-selectable trigger lets you choose active-high or active-low logic
- Supports up to 250V AC / 10A or 30V DC / 10A loads
- Screw terminals simplify wiring and quick diagnostics
