1 Channel 24V Relay Module For Arduino Silk Blue

BESTEP 1-Way Relay Module (≤36V, DC Power Supply)

Product Description:

The BESTEP 1-Way Relay Module is a high-quality, photocoupler-isolated relay designed for microcontroller and automation projects. With a maximum load of AC 250V/10A or DC 30V/10A, it ensures stable and reliable switching of high-power electrical devices.

This module features optocoupler isolation for enhanced protection and fault-tolerant design, meaning the relay remains inactive even if the control line is disconnected. The low-level trigger design ensures compatibility with most microcontrollers like Arduino, ESP32, Raspberry Pi, and STM32.

Key Features:

✔️ High-quality relay with up to 250V/10A AC or 30V/10A DC load
✔️ Optocoupler isolation for better stability and protection
✔️ Low-level trigger (5mA) for microcontroller compatibility
✔️ Green LED for power indication, Red LED for relay status
✔️ Screw terminal connectors for easy wiring

Interface & Connections:

📌 Module Power Input:

• VCC → 3.3V power supply
• GND → Ground
• IN → Low-level trigger to activate the relay

📌 Relay Output:

• NO (Normally Open) → Connects to COM when the relay is active
• COM (Common) → Shared terminal
• NC (Normally Closed) → Connected to COM when relay is inactive
