The TRICONEX 3626X is an Analog Input (AI) Module for the Tricon safety instrumented system (SIS), manufactured by Triconex (now part of Schneider Electric). It is designed to reliably receive and process analog signals (e.g., from temperature, pressure, or flow transmitters) from field devices in safety-critical applications. The "X" in the part number signifies it's part of the Triconex "X" series, which are often enhanced or later revisions of modules.

English Description

The Triconex 3626X is an Analog Input (AI) module used in the highly fault-tolerant Tricon safety instrumented system (SIS). This module is responsible for acquiring continuous analog signals from field transmitters (e.g., 4-20mA, 0-10VDC) and converting them into digital data for secure processing by the Tricon's Triple Modular Redundant (TMR) main processors. Its robust design, high accuracy, and extensive diagnostic capabilities are crucial for maintaining the integrity of safety functions where precise measurement is needed.

Key features and characteristics of the 3626X include:

• Manufacturer: Triconex (a brand of Schneider Electric).

• System Compatibility: Designed for use with the Tricon SIS, which typically operates on a TMR architecture for maximum availability and safety.

• Module Type: Analog Input Module.

• Number of Channels: The 3626X typically provides 16 analog input channels.

• Input Type: Commonly supports standard industrial analog input ranges, such as 4-20 mA current inputs and potentially voltage inputs (e.g., 0-5V, 0-10V, 1-5V). The module provides power for 2-wire transmitters (loop-powered).

• Isolation: Features channel-to-channel isolation and isolation from the system, which is vital for preventing ground loops and protecting the control system from electrical noise and potential faults on the field side.

• Diagnostic Capabilities: Includes extensive built-in diagnostics for each channel to ensure data integrity and detect potential issues:

• Open-circuit detection (wire break): Detects if a field wire is disconnected.

• Short-circuit detection: Detects if a field wire is shorted.

• Over-range/Under-range detection: Checks if the input signal is outside the expected limits.

• Discrepancy voting: In TMR systems, it might participate in voting mechanisms to ensure data consistency when multiple AI modules are used for redundant inputs. These diagnostics provide critical information for maintaining system health and pinpointing faults without compromising safety.

• Accuracy: Designed for high measurement accuracy, essential for precise control and safety interlocks.

• Hot Swappable: Designed for hot-swapping, allowing the module to be replaced online without interrupting the safety function of the system, minimizing downtime during maintenance.

• Safety Certification: As a component of the Tricon SIS, the 3626X contributes to the overall system's Safety Integrity Level (SIL) certification (typically SIL 3), ensuring it meets stringent international safety standards (e.g., IEC 61508/61511).

• Applications: Essential for acquiring safety-critical analog signals in various industries, including:

• Oil & Gas: Emergency Shutdown Systems (ESD), Fire and Gas (F&G) systems (e.g., for gas concentration monitoring), process safety (e.g., high/low pressure/temperature trips).

• Chemical & Petrochemical: Reactor control, critical temperature/pressure monitoring.

• Power Generation: Boiler water level, steam pressure, turbine speed monitoring for protection.

• Refining, Pharmaceuticals, Mining: Any application requiring reliable and fault-tolerant processing of analog inputs for safety.

The 3626X Analog Input Module is a fundamental component of the Tricon SIS, ensuring that critical continuous process information is accurately and safely acquired for system protection and control.
