5 ms scan of digital inputs Monitoring & Diagnostic The B30 is the single point for protection, control, metering, and monitoring in one integrated device that can easily be connected directly into DCS or SCADA monitoring and control systems like Viewpoint Monitoring. Advanced Automation The B30 incorporates advanced automation features including powerful FlexLogic programmable logic, communication, and SCADA capabilities that far surpass what is found in the average bus relay. The B30 integrates seamlessly with other UR relays for complete system protection. The internal operation of the B30 elements, logic, and outputs can be monitored in real-time to simplify commissioning and troubleshooting procedures.
Digital Equipment Corporation (DEC) further reduced cost for mass-produced minicomputers, and memory-mapped I/O into the memory bus, so that the devices appeared to be memory locations. This was implemented in the Unibus of the PDP-11 around 1969, eliminating the need for a separate I/O bus. [6] Even computers such as the PDP-8 without memory-mapped I/O were soon implemented with a system bus, which allowed modules to be plugged into any slot. [7] Some authors called this a new streamlined "model" of computer architecture. [8] Many early microcomputers (with a CPU generally on a single integrated circuit) were built with a single system bus, starting with the S-100 bus in the Altair 8800 computer system in about 1975. [9] The IBM PC used the Industry Standard Architecture (ISA) bus as its system bus in 1981. The passive backplanes of early models were replaced with the standard of putting the CPU and RAM on a motherboard, with only optional daughterboards or expansion cards in system bus slots.

Computers in the 1950s and 1960s were generally constructed in an ad-hoc fashion. For example, the CPU, memory, and input/output units were each one or more cabinets connected by cables. Engineers used the common techniques of standardized bundles of wires and extended the concept as backplanes were used to hold printed circuit boards in these early machines. The name "bus" was already used for " bus bars " that carried electrical power to the various parts of electric machines, including early mechanical calculators. [3] The advent of integrated circuits vastly reduced the size of each computer unit, and buses became more standardized. [4] Standard modules could be interconnected in more uniform ways and were easier to develop and maintain. Description [ edit] To provide even more modularity with reduced cost, memory and I/O buses (and the required control and power buses) were sometimes combined into a single unified system bus. [5] Modularity and cost became important as computers became small enough to fit in a single cabinet (and customers expected similar price reductions).

Overall system costs can be reduced with the B30, since there is no need for dedicated, or interposing, CTs. The B30 comes with advanced features, such as breaker failure, CT trouble detection, undervoltage supervision, and dynamic bus replica. With its extreme flexibility, which includes a CT ratio mismatch of up to 32:1 between terminals, the B30 is the ideal solution in a wide variety of bus differential applications. Part of the Universal Relay family, the B30 comes with a variety of versatile features, truly integrating protection, monitoring, metering, communication and control in one easy-to-use relay. The Universal Relay family offers a high degree of modularity in its design and functionality, providing superior performance in protection and control, while meeting the toughest requirements of the marketplace.
