Vesta Pro

The Vesta System Controller is the heart of the Vesta system. With support for Modbus and a wide range of industrial sensors, the Vesta Pro is designed for commercial / industrial applications. Like all Vesta controllers, the Pro is a networked web-enabled device that supports wireless sensors and includes the following:

Standard Features

  • 16 analog (sensor) inputs
  • 4 variable speed control outputs
  • 32 discrete (contact closure sensing) inputs
  • 32 discrete outputs (LED, relay control)
  • Built-in web server
  • Ethernet network port
  • Wireless Sensor Support
  • (2) 1 Wire Masters
  • Modbus
  • RS-232
  • All required software (including source code)


  • Wi-Fi Networking
  • Insteon Support

The Insteon support option allows the Vesta to communicate with and control selected Insteon devices.
