5V 2 Channel Solid State Relay (SSR) Low Level Trigger
VAT inclusive; Computed calculations added locally.
Overview
The 5V 2 Channel Solid State Relay (SSR) Low Level Trigger provides a convenient way to control electrical loads from microcontroller and embedded control systems. With two independently controlled channels, the module is useful for automation projects where multiple loads need to be switched from a single controller.
The low-level trigger design allows the relay channels to be activated using a LOW control signal, making the module convenient to integrate with many digital GPIO-based systems. It is suitable for Arduino automation, IoT projects, robotics, smart control systems, industrial prototypes, lighting control, and DIY electronics.
The solid-state switching approach provides electronic switching without the mechanical contacts found in conventional electromechanical relays. This makes an SSR module useful in applications requiring frequent switching and compact control hardware.

Product Technical Information
Technical Details
The 5V 2 Channel Solid State Relay (SSR) Low Level Trigger Module is designed to allow microcontrollers and digital control systems to switch compatible external electrical loads. It provides two independently controlled SSR channels, making it useful for projects that need to operate multiple loads.
2-Channel Control
The module provides two relay channels that can be controlled separately from a compatible microcontroller. This allows you to operate two independent outputs within the same project while reducing wiring and saving board space.
Low-Level Trigger
This module uses a low-level trigger configuration. A LOW signal applied to the appropriate control input activates the corresponding relay channel. This operating method can be convenient when interfacing the module with digital GPIO pins.
5V Control
The module is designed around a 5V control supply, making it suitable for many traditional Arduino-based control systems and other compatible electronics projects.
Solid-State Switching
Unlike mechanical relay modules, solid-state relays use semiconductor-based switching rather than moving mechanical contacts. This can provide benefits for applications involving frequent switching operations and compact control systems.
Wide Range of Applications
The module can be used for:
- Arduino automation projects
- IoT control systems
- Robotics projects
- Smart home prototypes
- Lighting control
- Electronic equipment control
- Industrial automation prototypes
- Microcontroller-based switching
- DIY electrical control projects
- Embedded systems
Important Load Compatibility
The actual load voltage, current, AC/DC compatibility, and switching characteristics depend on the specific SSR components used on the module. Always verify the relay's output specifications before connecting an electrical load. Do not exceed the manufacturer's rated limits, and use appropriate electrical protection and isolation when working with mains voltage.
