Description
Product Description
This 5V 4-Way Electromagnetic Relay Module is a practical and reliable switching solution designed for microcontroller-based control systems. It features a straightforward low-level trigger logic, making it intuitively compatible with common development platforms like Arduino, ESP32, and Raspberry Pi. The module operates without optical isolation, providing a direct and cost-effective interface between your digital control signals and high-power AC/DC loads.
Each of the four channels is equipped with a high-quality electromagnetic relay capable of handling substantial currents. The board includes bright status indicator lights for each relay, providing clear visual feedback of the switching state. Screw terminals ensure secure connections for both the control side and the load side, while the compact form factor makes it easy to integrate into control panels, smart home installations, and automation prototypes. This module is an excellent choice for hobbyists, students, and professionals seeking a simple, effective way to add robust switching capabilities to their projects.
Key Features
-
Low-Level Trigger Logic: The relay activates when the control signal pin is set to LOW (0V/GND), which aligns with the default output behavior of many microcontrollers.
-
Four Independent Channels: Control up to four separate electrical circuits or devices simultaneously from a single control board.
-
Dual-Purpose Relays: Each relay features SPDT (Single Pole Double Throw) contacts, allowing connection to Normally Open (NO) or Normally Closed (NC) terminals for flexible circuit design.
-
Clear Status Indicators: Each channel has a bright LED that illuminates when the relay is energized, providing instant visual confirmation of its state.
-
High-Current Switching: Robust relays are rated to switch loads up to 10A, suitable for a wide range of appliances and equipment.
-
Non-Optocoupler Design: A simplified, direct-drive circuit offers a reliable and economical solution for environments where high-voltage isolation is managed separately.
-
Screw Terminal Blocks: Provide secure and reliable wire connections for both 5V control power and the high-power load circuits.
-
Wide Compatibility: Works seamlessly with 5V logic microcontrollers and development boards using standard male-to-female jumper wires.
