1‑Channel 5V Relay Module — Opto‑Isolated Switch Board

Single‑channel relay module (5V) for switching AC/DC loads — optocoupler isolation and LED indicator options.

Key Features:

• Control Signal: Works with 5V TTL signals.
• Switching: Switches AC (up to 250V) and DC (up to 30V) loads.
• Relay Rating: Supports 5A at 240V AC.
• LED Indicator: Shows when the relay is ON.
• Wiring: 2×3-pin male header for easy connections.
• Microcontroller Compatibility: Works directly with Arduino without extra drivers.

The 5V 1 Channel Relay Module for Arduino is designed for controlling AC and DC appliances, such as motors, solenoids, lights, and fans. It supports switching up to 7250VAC@10A and 30VDC@10A. The module operates at 5V TTL and features screw terminals for easy connection (C, NC, NO). With 5mA trigger current, it includes a flyback diode to protect your microcontroller, and LED status indicators show relay on/off status. Ideal for Arduino applications, offering reliable and safe control.

Features:

1. Relay Ratings: Switches up to 7250VAC@10A and 30VDC@10A, suitable for AC and DC appliances.
2. Trigger Current: Low 5mA trigger current for efficient operation.
3. Working Voltage: Operates at 5V TTL signal.
4. Mounting Holes: Four 3.1mm diameter holes for easy mounting.
5. Screw Terminals: Easy connection with C, NC, NO terminals.
6. Fly back Diode: Protects the microcontroller from relay kickback.
7. LED Indicators: Shows ON/OFF status of the relay.
8. Protection: Transistor (BC547) used to safely drive the relay.
9. Microcontroller Compatibility: Works with Arduino.
10. Wide Application: Controls motors, solenoids, lights, fans, etc.
