ABB Safety Triguard 2 TMR Safety Products

ABB TMR Safety and Control

August Systems, founded in 1978, was the worldwide pioneer in the development of Triple Modular Redundant (TMR) processing for real time, fault tolerant control. August Systems became an ABB company in 1997 adding TMR technology to the well established Dual Redundant Safety systems developed within ABB. The new business group of ABB Safety has been established to offer a broad range of safety solutions to industry. The Triguard SC300E products are available as engineered systems from ABB or products for integration by third party system integrators and OEMs, enabling the technology to be made available to a wide range of customers and applications.

Product Family

The ABB Triguard SC300E TMR product family gives unrivalled performance in areas of reliability, availability, test coverage, diagnostics and simplicity of operation. Advances in technology and improved production methods add cost benefits that give significant price/performance advantages.

• Fewer unscheduled stoppages

highest availability, fault tolerant electronics with transient immunity and 3–2–0 or 3–2–1–0 voting

• Security for plant, product and people

fail-safe operation at all levels provides plant, product and personnel with the highest security

• Quality data

sequence of event and extensive diagnostics keep the operator informed

Highest Availability

The Triguard SC300E achieves the highest possible TMR availability (99.999%) 

by maximising the Mean Time To Failure (MTTF) and decreasing the Mean Time T

o Repair (MTTR). Modern low power integrated technology allows the TMR archite

cture to be cost effective for an increasing range of high integrity applications.

Simple to Use, Operate and Maintain

The Triguard SC300E TMR product functions as a single set of hardware

 and software. The three processors and triplicated I/O circuitry are trans

parent to the user. Purchasing a Triguard SC300E system will provide:

• Lowest Life Cycle Cost 

• The Maximum Safety and Availability 

• The Highest Level of Safety and On-Line Maintenance

Fail Safe Operation
