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.
The RM400 supports WiFi and cellular connectivity to Ranch Cloud and can sample traditional wired sensors, as well as sensors connected via the the RS10 Long Range Bluetooth® Transmitter, making new installations and upgrading existing installations easier than ever.
* Number of supported valves varies by configuration.
