Description
1. Product Description
The TRICONEX 8111 is a high-density expansion chassis designed for Tricon safety instrumented systems (SIS). It expands the system’s capacity by accommodating additional input/output (I/O) and communication modules, allowing industrial facilities to extend their control and safety functions without replacing the main chassis. It is used in critical process industries such as oil and gas, petrochemical processing, power generation, and chemical manufacturing.
The 8111 chassis supports up to eight logical module slots and includes two power-module positions. It connects to the main chassis through dedicated I/O expansion cables, supporting communication between the processor system and installed I/O modules. It is part of the Tricon v9–v11 chassis-based platform. Confirm the chassis revision, power-module configuration, slot arrangement, and cable requirements before installation.
