PX-A300 Industrial Edge Controller

"Modern monitoring for the controllers you already own."

The PX-A300 connects to any Modbus controller and adds a layer of monitoring, alarming and control on top of it. Keep your existing equipment. Get modern features anyway.

Its built-in edge processor (PytroAI) runs custom logic right at the site, and setup is done through a simple USB web interface. There's no proprietary software to install.
