Description

Product Name:

TRICONEX 8311N Discrete Input Module

Product Description:

The TRICONEX 8311N is a safety-critical discrete input module designed to interface with field devices such as limit switches, pushbuttons, and other binary (on/off) input signals. It is a key component of the Triconex Safety System, which is known for its fault-tolerant architecture that ensures safety and availability in process control environments. The 8311N module is designed to meet the requirements for high-performance, high-availability, and high-integrity operations in critical safety applications.

Product Parameters and Specifications:

• Module Type: Discrete Input (DI)
• Input Voltage: 24 V DC (Nominal), typically used in industrial control and safety systems.
• Number of Inputs: Typically, the module offers 12 discrete inputs, but this can vary depending on the system configuration.
• Input Type: Dry contact or wet contact, capable of handling a variety of field devices.
• Input Voltage Range: The input range generally supports 24V DC, but can also accommodate 48V DC in some configurations.
• Signal Conditioning: The module includes signal conditioning circuitry to convert input signals into readable signals for the safety system.
• Isolation: Provides electrical isolation between input channels and the control system to prevent electrical faults from propagating.
• MTBF (Mean Time Between Failure): High reliability and uptime are typical, with MTBF often exceeding 100,000 hours, making it ideal for mission-critical systems.
• Certification: The module is certified for use in SIL3 (Safety Integrity Level 3) systems, meeting the stringent standards for safety-critical applications in industrial environments.

Communication Protocol:

• The module communicates with the Tricon system via the Triconex I/O bus, utilizing the Tricon communication protocol.
• It is designed to interface with the Tricon Safety System Controller to facilitate communication and monitoring of field devices.

Product Use:

The TRICONEX 8311N module is designed to be used in safety instrumented systems (SIS), especially in applications where high reliability and fault tolerance are critical. Some typical uses include:

• Process Safety Systems: Monitoring and controlling safety-critical processes such as emergency shutdown systems, fire detection, and gas leak detection.
• Safety Instrumented Functions (SIFs): Integrated into safety loops where the detection of hazardous conditions requires an immediate and reliable response to mitigate risk.
• High-Availability Systems: Providing input signals from field devices to a Triconex controller, ensuring continued safe operation even in the event of a component failure.

Key Features:

• High Availability: The TRICONEX system offers fault tolerance through a triple-modular redundancy (TMR) architecture, ensuring that the system can continue to operate safely even if a fault occurs in one of the redundant channels.
• Flexibility: Supports a variety of input devices, such as limit switches, proximity sensors, and other binary input devices.
• Modular Design: Part of a modular I/O system that can be expanded or customized according to system requirements.
• Compliance with Safety Standards: Meets IEC 61508, ISO 13849, and IEC 61511 safety standards, which are essential for SIL-rated systems.

Applications:

• Oil and Gas: Emergency shutdown systems (ESD), gas detection, and wellhead control.
• Chemical Processing: Safety systems for reaction control, pressure relief, and hazardous material handling.
• Power Generation: Control of plant protection systems, turbine trip, and safety shutdowns.
• Pharmaceuticals and Food Processing: Critical monitoring of processes that could pose safety hazards.
