ABB Triguard SC300E Triple Module Redundancy

ABB Triguard SC300E Triple Module Redundancy

Product Overview: Developed by August Systems and incorporated into ABB in 1997. 

It can be used as an engineered system or as an integrated product in a variety of applications such as safety shutdown and process control in the

petrochemical, power and nuclear industries.

Product characteristics

High Availability: Modern low-power integration technology achieves up to 99.999% availability by maximising Mean Time Between Failure (MTTF) and minimising Mean Time To Repair (MTTR).

Ease of Use and Maintenance: Hardware and software integration, transparent to the user, with the lowest life cycle cost and support for online maintenance.

Fail-safe operation: Controllable failure modes for processor, input/output circuits, etc., defaulting to a safe state.

Fast Response: Scanning time resolution up to 10ms, suitable for high-speed control and event recording.

Fault Tolerance and Redundancy: Fully diagnostic and selective redundancy features to tolerate multiple non-concurrent faults and reduce false trips.

Transient Immunity: Physical and electrical isolation combined with asynchronous processors and software polling for immunity to transient errors.

Small footprint: ‘Plug and Play’ cabinet layout saves space and allows for easy cabling.

Hardware and Software Description

Hardware: Fully triple-redundant system architecture, including multiple chassis types, each with 10 slots for I/O modules and redundant power supplies. The processor is an Intel processor with a variety of storage and clock functions, and there are a variety of I/O modules with isolated signal paths, some of which support hot repair. There are also communication modules and various types of field terminal cards.

Software: Supports TriBuildTM, TriCommandTM and TriLogTM Windows-compatible software. TriBuild is used to develop and programme application logic; TriCommand provides real-time system control and monitoring; and TriLog is used for logging events and alarm messages.

International standards: ABB's quality system complies with international standards and is certified according to a number of certifications, such as BS EN ISO 9001 1994. products meet the requirements of many international standards and are subject to thorough testing and control.

Applicable Scenarios

Industrial production safety protection: In petroleum, chemical and other industries, it is used for safety shutdown, process shutdown and emergency shutdown systems. For example, in oil refineries, when abnormal conditions occur, such as temperature and pressure exceeding the safety range, Triguard SC300E can react quickly and start the shutdown procedure to safeguard personnel, equipment and products and prevent the accident from expanding.

Stability control in the energy sector: In power systems, for electrical stability and load control. It ensures stable operation of the power grid under different working conditions, avoids power fluctuations caused by sudden load changes and other problems, and guarantees the reliability of power supply. In power plants, it is used for turbine and compressor control to optimise equipment operation and improve energy conversion efficiency.

Precise control of complex processes: It is suitable for critical batch, sequence and interlock control as well as critical process control. In pharmaceutical, food processing and other industries with strict requirements on the production process, it can precisely control the production process to ensure the consistency and stability of product quality. For example, in pharmaceutical production, the temperature, pressure and time parameters of each production process are controlled in strict accordance with preset procedures.
