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.
Specifications:
- Operating Voltage (VCC): 5V DC
- Trigger Current: 5mA
- Maximum Load Capacity: AC 250V / 10A | DC 30V / 10A
- Output Contacts: NO (Normally Open), COM (Common), NC (Normally Closed)
- Dimensions: 50 mm × 26 mm × 18.5 mm (L × W × H)
- Mounting Holes: 4× 3.1 mm diameter (M3 screw compatible)
What you Get:
1 x Relay Board 5V 1-Channel, Optocoupler Isolated 10A, Selectable High/Low Trigger
