Telemetry Units

RM400 Monitoring & Control Unit

The flagship controller in the Ranch Systems lineup — a telemetry node, data logger, and valve controller in one, built to be the backbone of your monitoring and control system.

Monitoring & Control Unit

Overview

The RM400 is an advanced telemetry node, data logger, and valve controller capable of reading data from a variety of sensors and uploading it to the Ranch Cloud™ platform. It's built to be the backbone of your monitoring and control system, with a built-in display and keypad for in-field configuration, valve control, and data readout — plus advanced configuration over a cabled PC connection or the myRanch™ app.

RM400 can control up to 48 valves* and accepts multiple sensor input types. In the myRanch app, build fully automated irrigation programs in minutes — automatically optimized for the shortest run time, and dynamically adjusted for real-time conditions. It supports both WiFi and cellular connectivity, and samples traditional wired sensors as well as sensors connected via the RS10 Bluetooth® Transmitter, making new and upgraded installations easier.

*Number of supported valves varies by configuration.
