The TRICONEX 3511 is a part of the Tricon series of safety controllers from Schneider Electric, used in critical process industries for safety and control applications.

Product Name

• TRICONEX 3511: Safety Controller Module

Product Description

• The TRICONEX 3511 module is a Triple Modular Redundant (TMR) safety system used for process control, offering high availability and fault tolerance. It is designed to meet the highest levels of safety integrity for industries such as oil and gas, chemicals, power generation, and other critical infrastructure sectors.
• The 3511 is typically used in safety instrumented systems (SIS), where process safety and failure management are paramount.

Product Parameters and Specifications

• Type: I/O (input/output) module for the Tricon safety system.
• Redundancy: Triple Modular Redundant (TMR) design. It ensures that three separate channels process the input/output information, which improves reliability and fault tolerance.
• Communication: The module communicates with the rest of the Tricon system through high-speed backplane connections.
• Inputs/Outputs: It typically supports digital inputs and outputs; the number of channels depends on the specific model or configuration.
• Power Supply: Typically operates with a voltage range of 24V DC.
• Safety Integrity Level (SIL): Compliant with SIL 3 (Safety Integrity Level 3) as per IEC 61508 standards.
• Process Control Standards: Compliant with ISA 84.00.01, IEC 61508, and other industry safety standards.
• Environmental Conditions: Designed for harsh industrial environments, with a wide range of operating temperatures and tolerances for shock and vibration.

Key Features

• High Availability: Triple redundancy ensures that even if one channel fails, the system continues to operate with no loss of functionality.
• Fault Detection: Advanced diagnostics and self-checking mechanisms for early fault detection and preventive maintenance.
• Safety Focused: The system is built to operate with the highest safety integrity, ensuring reliable operation in critical applications.
• Modular Design: Allows for easy system expansion or upgrades, depending on the needs of the process.

Product Use

• Process Industries: It is typically used in industries that require high-reliability safety systems, such as:
  • Oil and gas production and refining
  • Chemical plants
  • Power generation (especially nuclear and fossil fuel plants)
  • Water treatment plants
  • Petrochemical and refinery operations
• Safety Instrumented Systems (SIS): It is used for controlling and monitoring processes in situations where a failure could lead to catastrophic consequences. The TRICONEX 3511 is crucial for managing emergency shutdown systems (ESD), fire and gas detection systems, and other safety-critical processes.
• High Availability Applications: The module is also used in environments where system downtime must be minimized, and reliability is paramount.
