Edge iO28

The Nube-iO, Edge iO-28 is a general purpose ethernet based building controller. There are 28 on board inputs and outputs. The controller can be setup as a master and or slave configuration for IO expansion.

The Edge iO-28 can be programmed as remote IO via flow based programming. Alternatively, for application specific control, the logic code can be loaded directly onto the Edge iO-28. 

Feature Spotlight

  • Equipment condition monitoring, HVAC, lighting, temperatures, and occupancy.

  • Collection, storage, and analysis of large amounts of data.

  • Structured export of data for use with other analysis tools.

  • Browser based programming. No need for expensive software and licensing.

  • Support for low cost hardware and sensors.

  • Compatibility and integration with third party products.

  • Remote Monitoring via system alarms, email, and SMS notifications, allows you to respond to issues as they occur. This reduces equipment downtime and can prevent unnecessary service calls.
