Intellitrol 2 Overfill Prevention Control Unit

Brand: Scully Signal Company
The Intellitrol®2 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.

The Intellitrol®2 is designed to be Faylsafe® and in the event of a failure (power, sensors, or internal electronics) the unit will enter a non-permissive (safe) state.

This state-of-the-art Dynamic Self-Testing® system controller provides overfill prevention, vehicle ground verification and vehicle identification operating in a single enclosure. The Intellitrol®2 also provides the user with comprehensive diagnostic information, both locally on the exterior of the control unit housing and remotely to the terminal automation system via RS-485 communications.
Features
  • Overfill prevention, ground verification and vehicle identification in one compact state of the art explosion-proof enclosure
  • Scully Dynacheck® automatic and continuous self-checking circuitry
  • Automatic detection of two-wire optic/thermistor or five-wire optic vehicle sensors
  • Monitoring of up to 8 two-wire or 15 five-wire vehicle sensors
  • Complete visual diagnostic display of overfill sensors’ status. Will not permit loading under any fault or wet sensor condition
  • When used with Scully Sensors, the Scully Intellitrol®2 Control Unit has been certified as part of a SIL 2 Overfill Prevention System
  • Easy connection to vehicles with rugged high impact industry standard plug and cable units
