DIAMOND-SIS automated backup (AIB) is new. It is a standalone safety instrumented system (SIS) that backs-up current process control trip logic. It also meets IEC 61511 requirements, declares the manufacturer.
This design delivers high integrity and process reliability. It’s available in single, dual, and triplicated channel configurations with on-line diagnostics, testing and maintenance capabilities. The single and dual channel systems are acceptable for SIL 2 while the triplicated version is certified by FM to SIL 3.
Designs include an IEC 61508 logic solver functionally independent from the process control system. It supplements existing logic and meets all appropriate safety standards. Full DIAMOND-SIS data are free.
