Description
Product Applications
The Tricon CX 8131X is a versatile I/O expansion chassis designed for Tricon CX Safety Instrumented Systems (SIS). It serves as the physical interface for connecting field instruments to the safety controller. Typical applications include:
- Emergency Shutdown Systems (ESD) and Fire & Gas (F&G) Systems.
- Critical Process Control in oil & gas, petrochemical, power, and nuclear industries.
- System Expansion: Adding I/O capacity to a Tricon CX main chassis (8120X) via a fault-tolerant I/O bus.
- Distributed I/O Architecture: When used with the Triconex Safety Intelligent Enclosure (SIE), it enables “near-process” deployment to reduce field wiring and cabinet space.
