RS-485 (Modbus RTU) Sensors, Relay and Lighting Control Modules

Relay Modules

Relay modules and RGB LED strip drivers can be controlled via Modbus RTU or by connecting external control buttons. This allows the modules to operate completely autonomously. For example, you can connect a wall switch and use it to control lighting.

This improves the overall reliability of the entire system. If the main controller, RS-485 bus, or other components of the system are inoperative, the lighting and wall switches continue to function normally.

As modules operate autonomously and almost all PLCs and controllers for home automation support Modbus RTU, during home improvements you can install modules for subsequent connection to the home automation system.

Relay modules allow you to connect multiple switches together. For example, you can use more than two switches connected in parallel. In this case, your circuit is fully operational even without the main controller.
