Relay Module 5V 1-Channel with Optocoupler Isolation (High/Low Level Trigger, 10A)

Overview:
This High-Performance 5V 1-Channel Relay Module provides reliable, optically-isolated switching for microcontroller projects, robotics, and home automation. Equipped with an SMD optocoupler, it protects your main control board from high-voltage transients while allowing flexible High- or Low-level trigger selection via an onboard jumper.

Key Features:

• Dual Trigger Logic: Jumper-selectable High-level or Low-level control input.
• Optical Isolation: SMD optocoupler separates control electronics from high-power switched loads.
• Safety First: Fault-tolerant design prevents accidental activation if the signal line fails.
• Visual Status: Dual LED indicators display board power (Green) and relay energization (Red).
• Simple Wiring: Universal screw terminals offer convenient direct-wire connections.
