Advantages & Features
- TMR Redundancy for High Reliability: Triconex MA2211-10052 adopts triple modular redundancy design, with independent signal acquisition and processing in each channel group. Even if a single module or channel fails, the system can still maintain normal operation, meeting the highest safety requirements of industrial processes.
- High-Precision Multi-Signal Acquisition: With ±0.05% FS measurement accuracy for analog signals and high-precision temperature sensing, Triconex MA2211-10052 can accurately capture subtle changes in process variables, providing reliable data support for safety interlock control.
- Hot-Swappable & Online Maintenance: The module supports hot-swappable replacement without shutting down the SIS system, and online calibration and diagnostics reduce maintenance downtime. This ensures continuous operation of critical processes and minimizes production losses.
- Compliance with Strict Safety Standards: Certified to IEC 61508 SIL 3 and API 615 standards, Triconex MA2211-10052 meets the safety requirements of explosive environments (ATEX/IECEx certification optional), making it suitable for high-risk industrial scenarios such as oil refineries and chemical plants.
Application Fields & Cases
- Oil Refinery FCC Unit Safety Control: A large oil refinery deployed Triconex MA2211-10052 in the SIS of its Fluid Catalytic Cracking (FCC) unit. The module collects reactor temperature, regenerator pressure, and catalyst flow signals, providing real-time data for safety interlock systems. In a sensor failure incident, the TMR redundancy design ensured uninterrupted signal acquisition, preventing an emergency shutdown of the unit.
- Chemical Plant Ammonia Synthesis Reactor Monitoring: A chemical plant uses Triconex MA2211-10052 to monitor the temperature, pressure, and hydrogen-nitrogen ratio of the ammonia synthesis reactor. The high-precision acquisition capability of the module enables early detection of abnormal process variables, triggering safety interlocks in a timely manner to avoid reactor overpressure or temperature runaway.
- Power Plant Boiler Safety System: A coal-fired power plant integrated Triconex MA2211-10052 into the boiler SIS, collecting furnace temperature, steam pressure, and water level signals. The module’s vibration resistance and wide temperature range adapt to the harsh environment of the power plant boiler room, ensuring stable operation for long periods and effectively preventing boiler explosions and other major accidents.

Selection Suggestions & Precautions
- Selection Suggestions: Triconex MA2211-10052 is the preferred choice for safety-critical processes requiring SIL 3 certification, multi-channel analog input, and TMR redundancy (e.g., oil refineries, chemical reactors). For small-scale SIS with fewer channels, Triconex MA2210-10051 (8-channel) is recommended. Explosive environment applications should select the ATEX/IECEx certified version.
- Precautions:
- Ensure proper grounding during installation to avoid electromagnetic interference affecting measurement accuracy.
- Use shielded cables for signal wiring, and separate analog and power cables to prevent signal distortion.
- Follow Triconex system configuration guidelines for module redundancy settings to avoid invalid redundancy due to incorrect configuration.
- Regularly perform online calibration (recommended every 6 months) to maintain measurement accuracy, and replace faulty channels/modules in a timely manner based on diagnostic results.
