SCULLY Intellitrol®2 unit is intended to serve as a secondary overfill protection system for loading operations.

It is intended for use in hazardous locations and is packaged in an explosion-proof (flameproof) enclosure and has both International and US approvals and certifications.

The Intellitrol®2 performs a variety of monitoring functions and provides a number of outputs to control valves, pumps and other systems including Terminal Automation Systems (TAS).
It has an integrated display to indicate system and monitoring status, a bypass capability, and communications for integration with TAS and other systems.

The Intellitrol®2 contains a pair of microprocessors, each with its own relay that monitors critical functions.
Only when both processors detect a safe condition will both relays close and make outputs permissive.
