Compatibility

Main Chassis: 8110 (v9–v11)

I/O Modules: Tricon 8xxx series (DI/DO/AI/AO/comms)

Max System: 1 main + up to 14 expansion/remote chassis; total 118 modules

I/O Bus Length: ≤ 30 m (100 ft) from main to last expansion chassis

Core Functions

TMR Fault Tolerance: Triple‑modular redundancy with 2‑out‑of‑3 voting; no single‑point failure.

I/O Expansion: 8 slots add up to 128 channels; ideal for large SIS needing more I/O.

Redundant Communication: Triplicated RS‑485 bus extends TMR to expansion chassis with no performance loss.

Hot‑Swap & Diagnostics: Online module replacement; comprehensive self‑diagnostics with ≤40 ms SOE resolution.

Seamless Scaling: Connects to 8110 main chassis; supports remote I/O up to 12 km (with repeaters).

Applications

Oil & Gas: ESD, F&GS, pipeline safety interlocks (large I/O counts).

Power Generation: Turbine/boiler protection, generator trip systems (expanded monitoring).

Chemical/Refining: Reactor safety, pressure/temperature control (SIL 3‑rated).

Heavy Industry: Furnace safety, large machine interlocks, high‑integrity processes.
