ICS Triplex Trusted Series Technical Notes

The ICS Triplex Trusted series represents one of the most widely deployed Safety Instrumented System (SIS) platforms in global heavy industry. Installed across petrochemical complexes, nuclear power stations, offshore platforms, LNG terminals, and refinery process units, the Trusted architecture is certified to IEC 61508 SIL 3 and operates as a Triple Modular Redundant (TMR) fault-tolerant control system. Its modular backplane design allows hot-swap replacement of I/O, communication, and controller modules without process shutdown — a critical requirement in continuous-operation facilities. The platform remains active in thousands of legacy installations worldwide, making spare parts availability and lifecycle support a primary operational concern for asset owners.
