Description
Phason AutoFlex Expansion Boxes

Each auxiliary module links directly to the main controller, helping organize wiring and simplify the integration of new equipment. This modular approach lets facilities scale their automation as needs change, ensuring the system can support ventilation and temperature-control adjustments throughout the year.
Designed for agricultural environments, the units feature durable enclosures and clearly labeled terminals to support dependable installation. By distributing connections across multiple modules, barns can upgrade or expand their systems without the cost or disruption of a full controller replacement.
Schmidt Building & Equipment offers these Phason-compatible components as part of our barn climate-control solutions. Our team can assess your current layout, verify compatibility, and coordinate installation support where needed.

Applications
These modules are commonly used in:
- Dairy and beef barns – adding ventilation or heating stages
- Calf and heifer facilities – connecting additional sensors or monitoring devices
- Freestall barns – increasing AutoFlex Connect capacity for larger systems
- Retrofit installations – upgrading older automation with added functionality
Integration Benefits
These modules help unify how barn equipment responds to changing conditions. Instead of relying on separate controls or manual adjustments, connected devices operate under a single management strategy. This improves consistency across ventilation, heating, and monitoring systems, especially when animal counts or weather vary throughout the year.
Centralized reporting also makes troubleshooting faster and more accurate. With all devices communicating through the same network, issues can be identified and resolved more easily. For operators, this means simpler oversight and more predictable barn conditions during peak demand.
