TRICONEX 3511 Product Specification
Product Overview：TRICONEX 3511
The TRICONEX 3511 is a high-performance TMR (Triple Modular Redundancy) pulse input module designed for mission-critical industrial automation systems. Engineered by TRICONEX, a global leader in safety-critical control solutions, this module is part of the Tricon series, renowned for its unparalleled reliability and precision in monitoring rotating equipment. The TRICONEX 3511 serves as a vital component in safety instrumented systems (SIS) and distributed control systems (DCS), enabling accurate acquisition and processing of high-frequency pulse signals from sensors in industries such as oil and gas, power generation, and manufacturing.
At its core, the TRICONEX 3511 integrates eight non-committed pulse input channels with 16-bit resolution, capturing signals ranging from 1,000 Hz to 20,000 Hz with ±0.01% accuracy17. Its TMR architecture ensures fault tolerance by independently processing inputs through three identical channels and voting on the results, minimizing the risk of single-point failures. This makes the TRICONEX 3511 ideal for applications where continuous operation and data integrity are non-negotiable, such as turbine speed control or compressor monitoring in offshore platforms.
In automation systems, the TRICONEX 3511 acts as a bridge between field devices (e.g., magnetic speed sensors) and higher-level control systems, converting raw pulse signals into actionable data for real-time decision-making. Its wide common-mode range (-100 VDC to +100 VDC peak-to-peak) and AC-coupled differential inputs provide immunity to noise and interference, ensuring stable performance in harsh industrial environments19. By combining high-speed processing with advanced diagnostic capabilities, the TRICONEX 3511 empowers industries to optimize equipment efficiency, reduce downtime, and comply with stringent safety standards like IEC 61508/SIL 337.

Main Features and Advantages：TRICONEX 3511
Triple Modular Redundancy (TMR): The TRICONEX 3511’s TMR architecture ensures fault tolerance by processing inputs through three independent channels and using a majority-vote mechanism. This design allows the module to continue operating even if one channel fails, making it suitable for safety-critical applications where downtime is unacceptable39.
High-Precision Signal Acquisition: With 16-bit resolution and ±0.01% accuracy, the module delivers precise measurement of pulse frequencies, enabling reliable speed and position monitoring of rotating machinery such as turbines and compressors. Its AC-coupled inputs and wide common-mode range further enhance noise immunity, ensuring stable performance in electrically noisy environments17.
Hot-Swap Capability: The TRICONEX 3511 supports hot-swappable replacement, allowing maintenance personnel to replace faulty modules without interrupting system operation. This feature minimizes downtime and reduces maintenance costs, particularly valuable in continuous-process industries like oil refining or power generation39.
SIL 3 Compliance: Designed to meet Safety Integrity Level 3 standards, the module is certified for use in safety instrumented systems (SIS), providing a robust foundation for emergency shutdown systems and process interlocks in high-risk environments79.
Flexible Configuration: The TRICONEX 3511 is compatible with TRICONEX’s TriStation 1131 software, offering intuitive programming and diagnostics. Users can configure input parameters (e.g., frequency range, signal filtering) to adapt to specific application requirements, ensuring seamless integration with existing control architectures39.
