Remote Accessory Controller (RAC)

The Remote Accessory Controller (RAC) extends connected irrigation monitoring, sensing, and control directly into the field. Designed for use with Husqvarna Ag irrigation systems, the RAC provides end-of-system visibility, GPS positioning, pressure monitoring, end gun automation, and remote control of pumps, valves, and auxiliary equipment across connected agricultural irrigation operations.

Built with integrated B-hyve smart irrigation connectivity technology, the RAC communicates wirelessly with the Center Pivot Controller Gen 2 (CPC Gen 2) to support real-time monitoring, automation, alerts, and field control through the B-hyve Ag mobile app.

Whether installed at the end of a pivot or at remote field locations, the RAC helps growers improve irrigation precision, automate field operations, and maintain better visibility across connected irrigation systems.

Key Benefits

• End-of-System Visibility – Monitor pressure and pivot position directly at the end of the system
• Precise End Gun Control – Supports up to three end guns for customized irrigation coverage
• Flexible Sensor Compatibility – Supports both 4–20 mA and 0–10V pressure transducers
• Reliable Wireless Communication – Communicates directly with CPC Gen 2 controllers using long-range radio connectivity
• Improved Water Management – Supports pressure-based VFD automation and irrigation optimization
• Multi-Purpose Field Control – Operates pumps, valves, and auxiliary equipment from a single field device
• Simplified Deployment – Designed for fast installation across pivot and remote field applications

How It Works

The RAC installs at the end of a center pivot or at remote irrigation equipment locations where additional sensing, automation, or field control is needed.

Using integrated GPS positioning, the RAC tracks pivot location in real time to support advanced irrigation programming, including end gun activation zones and position-based automation.

Built with integrated B-hyve smart irrigation connectivity technology, the RAC communicates wirelessly with the Husqvarna Ag Center Pivot Controller Gen 2 (CPC Gen 2) using 868 MHz or 900 MHz radio communication depending on regional requirements.

This enables reliable long-range field communication, remote monitoring, automation, alerts, and connected irrigation control through the B-hyve Ag mobile app without requiring additional communication infrastructure.
