Triconex 8112 High Density Main Chassis
– Product Overview
The Triconex 8112 is a high-density Remote Expansion (RXM) chassis specifically designed for use with the Tricon fault-tolerant control system. It is part of a scalable architecture that ensures high reliability and safety for critical industrial processes. The 8112 chassis accommodates up to six logical I/O slots and integrates seamlessly with Tricon Main and Expansion Chassis via triplicated fiber-optic connections, supporting long-distance communication and robust process control.
The 8112 chassis is primarily used in remote or extended I/O applications where communication distances exceed the standard copper I/O bus limits. It is engineered to maintain complete fault-tolerance through redundant power supplies, hot-spare capabilities, and dedicated RXM modules.
