Introduction
The ICS TRIPLEX T8311 Trusted TMR Expander Interface is the go-to solution when your safety-critical system needs more I/O headroom without compromising fault-tolerance. Designed for the T8300 chassis, the module extends Triple-Modular-Redundant (TMR) architecture up to 30 m on copper or 10 km over fibre, giving plants the freedom to distribute I/O racks exactly where they are needed. With 20 years of automation sourcing experience, PLC Autocontroller in Xiamen keeps the T8311 on the shelf and ready for same-day dispatch to any continent.
Key Advantages at a Glance
1. SIL 3 certified (IEC 61508) for the most demanding emergency-shutdown and fire-&-gas schemes
2. Hot-swap capability lets you add or replace expander nodes while the process stays live
3. 250 Mbps expander bus eliminates data bottlenecks, even when hundreds of additional I/O channels are added
4. On-board diagnostics via front-panel LEDs – no laptop required for first-line troubleshooting
