Triconex | 7400209-010 | Card Module

Description

The Triconex 7400209-010 is a high-reliability Power Module (often referred to as a Power Supply Card) designed for the Triconex Triple Modular Redundant (TMR) safety-instrumented system. This module is typically found in the Triconex 3008 or 3009 series controllers.

Specifications

• Part Number: 7400209-010
• Model Series: Triconex Version 9 / 10 Systems
• Input Voltage: 24 VDC (Nominal)
  
• Output Voltages: Multi-rail regulated DC (typically providing +5.1 VDC and other logic-level voltages to the backplane).
• Architecture: Fault-tolerant, redundant design.
• Cooling: Convection cooled (within a forced-air rack environment).
• Status Indicators: Front-panel LEDs for "Pass," "Fault," and "Load."

Features

• Triple Modular Redundancy (TMR): Like all Triconex components, this power module is designed to work in a redundant configuration. If one power module fails, the remaining modules in the rack take over the load seamlessly without interrupting the safety function.
• Hot-Swappable: The module can be replaced while the system is online and "under power" (Live), ensuring zero downtime for critical safety loops in oil & gas or chemical processing.
• Diagnostic Monitoring: The 7400209-010 continuously monitors its own internal temperature and output voltage levels. Any deviation outside of strict tolerances triggers a system-wide alarm via the "Fault" LED and the processor's diagnostic table.
• Isolation: Provides high-grade galvanic isolation between the field-side 24V supply and the sensitive logic-side backplane components to prevent surge damage.
  
• Ruggedized Build: Specialized for SIS (Safety Instrumented Systems) and SIL3 applications, featuring vibration resistance and high-grade electrolytic capacitors for long service life.
