TRICONEX+4351B

Description

The TRICONEX 4351B is a safety-related input/output (I/O) module designed for use in safety-critical applications.

Product Name:

TRICONEX 4351B — Digital Input/Output Module

Product Description:

The TRICONEX 4351B is an I/O module used in the Triconex Safety System. It provides both digital inputs and outputs that interface with field devices, enabling the safety system to monitor and control critical processes. The module is designed for use in high-reliability, safety-critical environments where system integrity is essential to prevent accidents or disasters.

The 4351B is capable of redundancy and fault-tolerant operation, ensuring continuous monitoring and control even in the event of a failure. It supports a wide range of field devices, including sensors, actuators, and switches, and is designed for easy integration into a Triconex system architecture.

Product Parameters & Specifications:

• Input Type: Digital (typically 24V DC)
• Output Type: Digital (typically 24V DC or relay outputs)
• Number of Inputs/Outputs:
  • Typically, 16 or 32 digital I/O points (configurable).
  • Can be configured for either discrete inputs, discrete outputs, or a mix of both.
• Input Voltage Range:
  • Input: 24 VDC (nominal)
  • Output: 24 VDC (nominal) or relay contacts, depending on the configuration.
• Response Time:
  • Typically < 10 ms for input signal detection.
  • Output response times depend on the load and configuration but are designed to be very fast for real-time control.
• Isolation:
  • Galvanic isolation between field inputs/outputs and system logic.
  • High voltage isolation (typically 1500 V AC) for improved protection and reliability.
• Signal Conditioning:
  • Features such as over-voltage and under-voltage protection, filtering, and debouncing to ensure accurate signal processing.
• Communication Protocol:
  • Integrated with Triconex Safety Systems using the Tricon communication network, a proprietary protocol designed for high-availability, fault-tolerant systems.
  • Connects with other safety I/O modules via redundant communication paths to ensure system reliability.
• Mounting:
  • Standard DIN rail mounting for easy installation and maintenance.
  • Designed for industrial control panels and cabinets.
• Redundancy:
  • Hot-standby redundancy with automatic failover to ensure continuous operation even if one module fails.
• Operating Temperature Range:
  • Typically -40°C to +70°C, depending on the model and environmental conditions.
• Environmental Protection:
  • Rated for industrial environments, often with an IP20 enclosure (indoor use) for protection from dust and indirect water exposure.
• Certification:
  • Typically certified to major safety standards such as IEC 61508, ISO 13849, SIL 3, and other relevant industrial safety certifications.

Product Use:

The TRICONEX 4351B module is primarily used in industries where safety, reliability, and fault tolerance are critical, including:

• Oil & Gas: To ensure safety in offshore platforms, refineries, and pipelines, where process control and emergency shutdown systems (ESD) are crucial.
• Chemical Processing: To monitor and control safety-critical operations, prevent hazardous material leaks, or respond to alarms quickly in case of dangerous situations.
• Power Generation: To monitor and control plant equipment such as turbines, boilers, and generators, ensuring plant safety and reliable power generation.
• Mining and Metallurgy: To monitor safety systems in mining operations and metallurgical plants.
• Transportation and Infrastructure: Used in the monitoring and control of safety systems for transportation networks (e.g., rail, aviation) and critical infrastructure.
