Overview
The RM400 is an advanced telemetry node, data logger, and valve controller capable of reading data from a variety of sensors and uploading that data to the Ranch Cloud™ platform.
The RM400 is built to be the backbone of your monitoring and control system. It is designed for ease of use, with a built-in display and keypad interface for in-field configuration, valve control, and data readout. Advanced configuration is available using a cabled PC connection or by real-time cloud server connection using the myRanch™ app.
The RM400 can control up to 48 valves* and provides multiple sensor input options. Using the myRanch app, you can create multiple, fully automated irrigation programs in a matter of minutes. Programs can be automatically optimized for the shortest possible run time, and dynamically adjusted based on real-time environmental conditions.
* Number of supported valves varies by configuration.
