Description

Product Name:

TRICONEX 3721 I/O Module

Product Description:

The TRICONEX 3721 is an input/output (I/O) module designed to interface field devices with the Triconex Safety System (Tricon). This module is used for input and output signal processing, and it communicates with the Tricon Safety System to monitor critical plant variables, such as pressure, temperature, and flow, to ensure safe operational parameters are maintained.

The TRICONEX 3721 typically supports a combination of digital and analog signals, enabling monitoring of both discrete (on/off) and continuous (varying) physical parameters. It can be used in both Fail-Safe and High-Availability configurations depending on the application needs.

Product Parameters:

• Input Types:
  • Digital Inputs: On/off signals (e.g., from limit switches or pushbuttons).
  • Analog Inputs: Continuous signals (e.g., 4-20mA, 0-10V for pressure, temperature, flow sensors).
• Output Types:
  • Digital Outputs: Control signals for actuators or alarms (e.g., valves, relays).
  • Analog Outputs: Control signals to devices requiring variable control (e.g., proportional control valves).
• Communication Protocols:
  • TRICONEX modules typically communicate over proprietary safety networks like Tricon’s TMR (Triple Modular Redundant) architecture, ensuring high reliability and fault tolerance.
  • Modbus or HART may also be supported, depending on the configuration.
• Redundancy & Fault Tolerance:
  • The Triconex system uses Triple Modular Redundancy (TMR), where three processors work in parallel and vote on the output to ensure system reliability.
  • It can handle faults such as sensor failures or communication issues.
• Power Requirements:
  • Typically powered from the Triconex Safety System or an external 24V DC power supply, depending on the system design.

Specifications:

• Input Voltage Range (for Analog Inputs): 4-20mA or 0-10V
• Input Range for Digital Signals: 24V DC (depending on module configuration)
• Output Voltage: Typically 24V DC (for digital outputs)
• Temperature Range: Typically operates within -20°C to +60°C (varies by model)
• Environmental Conditions: Designed for harsh industrial environments; IP20 or IP66 rated depending on installation.
• Response Time: Dependent on application, but generally low-latency for safety-critical systems.

Product Use:

• Safety Instrumented Systems (SIS):
  • Used for continuous safety monitoring and control in industries such as oil & gas, chemical, and petrochemical.
• Emergency Shutdown Systems (ESD):
  • The 3721 module plays a key role in ensuring quick, safe shutdowns in the event of an unsafe process condition.
• Process Control:
  • It can be used in systems requiring process monitoring, where both safety and operational performance are crucial (e.g., temperature, pressure, flow control).
• Process Interlock and Alarm Systems:
  • This module ensures that critical alarms and process interlocks are activated when system conditions exceed safe limits.
• Fire & Gas Systems:
  • Can be integrated into fire and gas detection systems to control emergency responses based on sensor data.
