Dimmer Module DIN rail, 2 Channel, 3.3V/5V logic, 8A/600V per channel

 The AC Dimmer is a DIY module—not a finished device—that you integrate into your project by connecting it to your microcontroller. Designed to regulate alternating current (AC) voltage, it safely handles up to 8A per channel. Originally designed for smooth control of lamps and heating elements—not merely simple on/off switching—this versatile module also supports adjustable operation for fans, pumps, air purifiers, and more.

Dual-Channel Dimmer - Designed for versatility, the four-channel dimmer lets you manage up to four distinct devices concurrently, with individual settings for each channel. Perfect for complex setups, this module ensures each connected device—be it lights, fans, or other appliances—receives the precise control required for smooth operation.

DIN Rail Mount - Enhance your installation with the four-channel dimmer that comes in a DIN rail mountable enclosure. This design allows for secure and convenient mounting in electrical boxes, on walls, or within equipment designed for DIN rail applications. It offers both stability and easy removal for maintenance or upgrades, making it an ideal choice for integrated smart home or industrial projects.

This dimmer is especially useful for smart home projects. With our comprehensive tutorials and user guides, you can build a fully customized solution. For example, you might:

• Adjust lighting: Gradually turn lights on or off to create a comfortable ambiance.
• Expand functionality: Add temperature sensors to manage heaters or incorporate web interfaces and dashboards.
• Automate your home: Connect the module to cloud services like HomeAssistant or even control it with voice assistants.
• Save energy: Program schedules for turning devices on and off, reducing energy consumption.

We provide extensive documentation and instructions not only for Arduino but also for other platforms. You can find guides on using the ESPHome component for integration and automation through HomeAssistant, as well as detailed instructions for connecting and configuring the Tasmota application. These resources ensure that whether you're using Arduino, ESP32, or another platform, you have all the support you need.

The dimmer’s design separates the high-power AC section from the low-power control section to protect your microcontroller. It supports both 5V and 3.3V logic levels, making it a great match for popular platforms such as Arduino and ESP32. The  rbdimmerESP32.h  library simplifies control by managing interrupts and timing, allowing you to focus on expanding your project’s features without complex coding.

Whether you’re creating a simple DIY lighting system or a more advanced smart home setup, our extensive support resources are here to guide you every step of the way.
