The ICS TRIPLEX T8451 is a 24Vdc digital output module of the Trusted TMR (Triple Modular Redundancy) series, designed for high-integrity control execution in safety instrumented systems (SIS) and critical industrial applications. As a Rockwell Automation-owned ICS Triplex product, it features 40 individually isolated digital output channels, organized into 5 independent power groups (8 channels per group), each processed by three redundant circuits with 2-out-of-3 voting logic to eliminate single-point failures. Equipped with comprehensive diagnostics, 1ms-resolution event logging, hot-swappable capability, and electronic short-circuit protection, it ensures reliable detection of stuck-on/off faults, precise output control, and seamless online maintenance. Certified to IEC 61508 SIL 3, the T8451 integrates with Trusted SIS to support emergency shutdown (ESD), fire & gas, turbine protection, and BPCS in oil & gas, power generation, chemical, and marine industries, delivering 99.999% system availability and enhanced operational safety.
