Redundancy at all levels

To achieve the highest possible availability, Advant Controller 450 can be equipped with backup redundancy for MasterBus 300/300E, Advant Fieldbus 100, power supplies, voltage regulators, backup batteries, battery chargers, central units (CPUs and memories) and I/O boards for regulatory control. The central unit redundancy is of a patented hot standby type, offering bumpless changeover in less than 25 ms.

Enclosures Advant Controller 450, equipped with local S100 I/O, consists of one CPU rack and up to five I/O racks. Optical bus extension makes it possible to distribute the S100 I/O up to 500 m (1,640 ft.) away, thus reducing the amount of field cabling required. The I/O racks are designed for installation in cabinets with a swing-out frames, permitting access to both the front and the rear of racks for ease of installation and maintenance. The external connections are routed through connection units normally fitted inside, at the back of the cabinets for marshalling and noisesuppression purposes. Cabinets with various degrees of protection are available, e.g. ventilated, tropical and sealed, with or without heat exchangers.
