SKU: EB0047111
Favorites
Key Features
- High Load Capacity: Supports heavy-duty switching up to 250V/10A AC or 30V/10A DC via high-quality Normally Open (NO) interfaces.
- Optocoupler Isolation: Utilizes SMD optocoupler technology for superior interference rejection and stable performance with only 5mA trigger current.
- Dual-Trigger Logic: Features a versatile jumper setting that allows you to switch between High-Level or Low-Level triggering to match your MCU.
- Fault-Tolerant Safety: Includes a fail-safe design—even if the control line is disconnected, the relay remains in its current state to prevent accidental switching.
- Plug-and-Play Design: Human-centered interface with robust screw terminals for secure wiring and dual LED status indicators (Power/Relay State).

Description
The Elecbee 1-Channel 5V Relay Module is a versatile, high-reliability solution for controlling high-voltage appliances from low-power microcontrollers. Whether you are using an Arduino, Raspberry Pi, or STM32, this module provides safe Optocoupler Isolation, ensuring that high-voltage noise or back-EMF never reaches your sensitive control board.
This module features a Human-Centered Interface with easy-to-use screw terminals for the input (DC+, DC-, IN) and output (NO, COM, NC) connections. A unique feature of this board is the High/Low Level Trigger Selection jumper, allowing for universal logic compatibility. Technical highlights include:
- Input: 5V DC (DC+ / DC-).
- Triggering: Adjustable via jumper (Short to LOW for low-level; Short to HIGH for high-level).
- Output Contacts: Normally Open (NO), Common (COM), and Normally Closed (NC).
- Status Indicators: Green LED (Power) and Red LED (Relay Status).
- Mounting: 44.5mm x 20.5mm hole spacing (3.1mm holes).
Ideal for IoT home automation, industrial control, and robotics, this Elecbee Relay Board is designed for 24/7 reliability. Its fault-tolerant design keeps your project safe by preventing accidental relay activation during signal loss, making it a professional-grade choice for both hobbyists and engineers.
