ICS TRIPLEX 9300 9832 9802 | Trusted System Components

Description

ICS Triplex T9300 Trusted Controller Chassis

• Model Number: T9300
• Description: The T9300 is the main 19-inch rack-mount chassis for the Trusted system. It provides the mechanical housing and the high-speed “Trusted Inter-module Bus” backplane that facilitates communication between the processor and I/O modules.
• Key Features:
  • Capacity: 20 slots for I/O and communication modules.
  • Redundancy: Supports redundant power distribution and dual-bus communication.
  • Robustness: Designed for high-availability environments with integrated cooling management.

ICS Triplex T9832 Trusted 120V DC Digital Input Module

• Model Number: T9832
• Type: 32-Channel Digital Input Module (TMR)
• Voltage Rating: 120V DC
• Technical Parameters:
  • Channels: 32 isolated points.
  • Architecture: Triple Modular Redundant (TMR) for Fault Tolerance.
  • Self-Diagnostics: Continuous testing for “stuck-at” faults and line monitoring (Open/Short circuit detection).
• Description: The T9832 interface monitors field signals in high-voltage DC environments. Because it is TMR, every input signal is voted upon by three internal slices to ensure a single component failure cannot cause a false trip or a failure to respond.

ICS Triplex T9802 Trusted 24V DC Digital Input Module

• Model Number: T9802
• Type: 40-Channel Digital Input Module (TMR)
• Voltage Rating: 24V DC
• Technical Parameters:
  • Channels: 40 points.
  • Input Delay: Configurable (typically < 10ms).
  • Safety Rating: SIL 3 certified.
• Description: The T9802 is one of the most common I/O modules in the Trusted family. It provides 40 channels of 24V DC digital inputs, offering high density and TMR reliability for standard safety loops, such as emergency shutdown (ESD) buttons and pressure switches.

Application Areas

These components are specifically engineered for Safety Instrumented Systems (SIS). They are standard in:

• Emergency Shutdown (ESD): Immediate halting of processes in hazardous conditions.
• Fire and Gas (F&G) Systems: Monitoring flame and gas detectors across large industrial sites.
• Burner Management Systems (BMS): Safe sequencing of boilers and furnaces.
• Turbine Control: High-speed protection for large rotating machinery.

Operational Precautions

• Module Positioning: Ensure modules are seated firmly in the T9300 chassis. The Trusted system uses a “live” backplane, but modules should be inserted using the lever locks to ensure all pins engage simultaneously.
• Configuration: All TMR voting logic and threshold settings must be configured via the Toolset engineering software. Verify that the I/O mapping matches the physical wiring.
• Field Power: While the modules monitor the signals, the field sensors typically require an external 24V or 120V power source. Ensure this power is filtered and monitored to prevent “System Fault” alarms caused by external power dips.
• Redundancy Links: For the highest availability, ensure the redundant power cables at the rear of the T9300 chassis are connected to independent UPS circuits.
