The Triconex 3501E/3501T is a Triple Modular Redundant (TMR) digital input module for Tricon systems, ensuring high-integrity input processing. Its three isolated channels independently handle data, and the main processors vote on inputs to guarantee maximum safety and system availability. Moreover, optical isolation maintains signal integrity between field devices and the Tricon system.
Key Features
- Triple Modular Redundancy (TMR): Each channel processes inputs independently, providing high reliability and fault tolerance.
- Continuous Diagnostics: Each channel undergoes ongoing checks; fault indicators activate if failures occur.
- Stuck-ON Detection: The module self-tests to detect inputs failing to switch OFF, enhancing system safety.
- Hot-Spare Capability: Supports hot-spare operation, maintaining functionality even if one module fails.
- Optical Isolation: Isolates and conditions signals between field devices and Tricon systems for accurate data transmission.
