‌Rockwell ICS Triplex T9432 Product Description‌

The ‌ICS Triplex T9432‌, part of Rockwell Automation’s ‌Trusted‌ product line (formerly known as ‌Trusted TMR‌), is a ‌high-integrity, Triple Modular Redundant (TMR) Programmable Safety System Controller‌.

Below are its core description and key features:

1. ‌Core Purpose: Safety-Critical Control‌

   • ‌Primary Mission:‌ Designed to execute the highest level safety functions, particularly in applications where failure could lead to catastrophic consequences.
   • ‌Safety Integrity Level:‌ Meets or exceeds ‌SIL 3 (IEC 61508 / IEC 61511)‌ and ‌PLe (ISO 13849-1)‌ requirements – the highest levels in functional safety.

2. ‌Core Technology: Triple Modular Redundancy (TMR)‌

   • ‌Architecture:‌ The controller consists of ‌three completely independent and identical processing channels‌ (A, B, C), each running on separate hardware and separate power supplies.
   • ‌Operation:‌ All three channels execute the same program logic in parallel.
   • ‌Voting Mechanism:‌ Output signals pass through a ‌safety voter‌ for ‌2-out-of-3 (2oo3) voting‌ before being sent to field devices. The voter produces a valid output only if at least two of the three channels agree. This ensures safe and correct operation even if a single channel fails (hardware or software fault).
   • ‌Fault Detection & Diagnostics:‌ Features robust internal diagnostics capable of real-time fault detection in each channel. Upon detecting a channel fault, the system isolates it, signals an alarm, and continues operating using the remaining healthy channels for 2oo3 voting, providing continuous fault tolerance.

3. ‌Key Characteristics:‌

   • ‌High Availability:‌ The TMR architecture ensures continued, uninterrupted operation even if one channel fails, significantly improving system availability (reducing unplanned downtime).
   • ‌High Reliability:‌ Redundant design and high-quality components ensure extremely high overall reliability.
   • ‌High Safety:‌ 2oo3 voting and powerful diagnostics form the foundation for achieving the highest safety integrity levels (SIL 3 / PLe).
   • ‌Online Maintenance:‌ Supports ‌hot swapping‌, allowing diagnosis, repair, or replacement of individual faulty modules (e.g., a processor card or power supply in one channel) without shutting down the entire control process. This is critical for industrial facilities where continuous operation is essential (e.g., refineries, chemical plants, power plants).
   • ‌Deterministic Performance:‌ Provides predictable scan times and response times, meeting the demands of safety-critical control.
   • ‌Comprehensive Diagnostics & Alarming:‌ Delivers detailed diagnostic information, precisely indicating fault locations (channel level, module level), facilitating rapid maintenance.

4. ‌Hardware Configuration:‌

   • ‌Modular Design:‌ The T9432 controller is a core component within the Trusted system, typically housed in a rack.
   • ‌Processor Module:‌ Contains three independent CPUs.
   • ‌Power Supply Module:‌ Usually configured redundantly.
   • ‌Communication Modules:‌ Used for communication with engineering stations (programming/configuration), operator stations (HMI), historians, and third-party systems (e.g., DCS). Supports various protocols (often proprietary Trusted protocols, sometimes others via gateways).
   • ‌I/O Subsystem:‌ The T9432 controller connects via a dedicated high-speed bus (e.g., TRISTATION bus) to similarly TMR-based ‌safety I/O modules‌. These I/O modules also utilize a three-channel design – input signals are read by three independent channels, and output signals undergo 2oo3 voting before driving field actuators. Common I/O types include Digital Input (DI), Digital Output (DO), Analog Input (AI), Analog Output (AO), Relay Output (RO), etc.

5. ‌Software:‌

   • Uses ‌Trusted Configuration Manager (TCM)‌ software for hardware configuration, logic programming (typically using Function Block Diagram – FBD or Ladder Diagram – LD), testing, simulation, diagnostics, and documentation management. TCM is specifically designed for developing and safety-certifying high-integrity TMR applications.

6. ‌Typical Application Areas:‌

   • ‌Process Industries:‌
     • Oil & Gas (Upstream Platforms, Refineries, Pipelines): Emergency Shutdown (ESD) Systems, Fire & Gas (F&G) Systems, Burner Management Systems (BMS), Process Shutdown (PSD) Systems.
     • Chemical: Safety Instrumented Systems (SIS), Reactor Safety Interlocks, High-Integrity Process Control.
     • Pharmaceutical: Critical Batch Control and Safety Interlocks.
   • ‌Energy:‌
     • Thermal Power Plants: Boiler Protection Systems, Turbine Trip Systems.
     • Nuclear Power Plants (Non-Nuclear Safety Class): Ancillary System Safety Controls (e.g., Containment Cooling, Emergency Diesel Generator Start).
   • ‌Other:‌
     • Large Compressor Train Protection.
     • Offshore Platform Critical Safety Control.
     • Any industrial safety application demanding the highest levels of functional safety, high availability, and fault tolerance.

7. ‌Important Background Information:‌

   • ‌ICS Triplex:‌ Originally an independent company specializing in high-integrity control systems, well-regarded for its TMR technology. Acquired by Rockwell Automation, its product line was integrated under Rockwell’s Trusted brand.
   • ‌T9432 Model:‌ The T9432 is a specific controller model/series. This series may include different performance levels or configuration options. As technology advances, Rockwell releases updated Trusted controller models (e.g., newer Trusted TMR Controllers), though the T9432 represents a mature and proven generation of this platform.
   • ‌Obsolescence Status:‌ It is important to note that ‌the T9432 is an older model and Rockwell Automation typically lists it as “Obsolete” or “Legacy”‌. This signifies new orders are no longer accepted, but limited support and spare parts supply are provided for a defined period. New projects would typically be recommended to use more current Trusted TMR controller models (e.g., based on more modern processors).
