TRICONEX+4351B

Description

The Triconex 4351B is part of the Triconex product line by Schneider Electric, designed for high-reliability, critical process safety and control applications.

Product Name:

Triconex 4351B – Analog Input Module

Product Description:

The Triconex 4351B is an analog input module used in the Tricon safety system to provide input for continuous, analog signals from field devices like sensors, transmitters, and controllers. This module is designed for critical safety applications requiring high availability, reliability, and fault tolerance. The 4351B is specifically part of the Triconex family of systems, used in industrial automation and process control for safety-critical environments.

This module receives analog signals, converts them into digital signals, and processes them for monitoring and controlling safety systems in industries where precision and reliability are paramount.

Key Features:

• High reliability and fault tolerance: The Triconex 4351B is built for safety-critical operations, with redundancy and diagnostics to ensure the highest levels of system uptime and integrity.
• Real-time, continuous monitoring of analog signals such as temperature, pressure, and flow rate.
• Easy integration with the Tricon system for seamless communication with safety controllers.
• Built-in diagnostics to identify faults and assist with system maintenance.

Product Parameters and Specifications:

• Input Channels: Typically, the Triconex 4351B module supports 8 to 16 analog input channels, depending on configuration.
• Signal Type: Supports a wide range of industrial signals such as 4-20 mA, 0-10 V, and others.
• Accuracy: High accuracy (typically within 0.1% of full scale for certain types of inputs).
• Input Range: The range of input values depends on the type of signal being processed. For example, the module might accept 4-20 mA current loops or 0-10 V voltage signals.
• Resolution: Typically 12-bit or 16-bit resolution for analog-to-digital conversion.
• Isolation: Provides galvanic isolation for each input channel to minimize noise and electrical interference.
• Power Supply: Requires a nominal voltage supply (e.g., 24 VDC), as common with industrial control systems.
• Temperature Range: Designed to operate in harsh environments, typically with a temperature range from -40°C to +70°C.
• Dimensions: Typically compact, designed to fit into standard rack-mounted enclosures.
• Mounting: Can be installed in a standard Triconex rack or chassis.

Applications:

• Safety Instrumented Systems (SIS): The 4351B is typically used in Safety Instrumented Systems for monitoring parameters like pressure, temperature, and level to prevent process upsets or failures.
• Process Control: Integration into process control systems where precise analog input is required to maintain safe and reliable operation.
• Critical Infrastructure: Used in industries such as oil & gas, chemical manufacturing, power generation, and more, where safety and system reliability are paramount.

Product Use:

The Triconex 4351B module is primarily used to integrate analog signals from field devices (such as pressure sensors, temperature sensors, or flow meters) into the Triconex Tricon safety system. This allows for real-time monitoring of critical parameters and facilitates automatic protective actions in case of an unsafe condition.

The module provides input to safety instrumented systems (SIS) and helps in:

• Monitoring process parameters such as temperature, pressure, flow, and level.
• Initiating safety actions when pre-set limits are exceeded (e.g., triggering alarms, initiating shutdown procedures).
• Supporting high availability and fault tolerance in critical operations.
