Description

The ICS Triplex T8191 is a Trusted Single Slot Width Shield designed as an integral component of the ICS Triplex Trusted TMR (Triple Modular Redundant) safety system. The ICS Triplex T8191 provides essential physical and environmental protection for I/O and communication modules installed within the Trusted chassis, shielding sensitive electronics from dust, moisture, electromagnetic interference (EMI), and other industrial hazards. Manufactured by Rockwell Automation under the ICS Triplex brand, the ICS Triplex T8191 is engineered to meet the stringent demands of safety-critical industrial automation environments.

Overview Manuals Engineering Considerations Product Applications Physical Installation

Features:

  • Triple Modular Redundant (TMR), Fault Tolerant (3-2-0) Operation
  • Hardware Implemented Fault Tolerant (HIFT) Architecture
  • Single-Width Slot Shield Design
  • Hot Replacement Capability
  • Front Panel Health & Status Indicators
  • TÜV Certified IEC 61508 SIL 3
The ICS Triplex T8191 leverages the proven Hardware Implemented Fault Tolerance (HIFT) architecture that defines the entire Trusted product family. Within the Trusted system, all critical components are triplicated, and the ICS Triplex T8191 contributes to this design by ensuring that the protected modules maintain their integrity under harsh operational conditions. The system operates on a 3-2-0 principle: with three parallel channels active, the system remains fully operational; if one channel fails, the system continues in a fail-operational state; a second failure in a parallel circuit triggers a fail-safe shutdown. The ICS Triplex T8191 supports this fail-operational/fail-safe philosophy by providing robust physical containment for the modules it protects.

The T8191 ICS Triplex Single-width slots may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The ICS Triplex T8191 is certified to IEC 61508 SIL 3 by TÜV, confirming its suitability for use in applications requiring the highest levels of safety integrity. Industries such as offshore oil and gas production, refining, chemical processing, and power generation rely on the ICS Triplex T8191 to maintain the reliability of their emergency shutdown (ESD) systems and other safety-critical control functions. The ICS Triplex T8191 enables hot replacement of protected modules, meaning maintenance personnel can swap out I/O or communication modules without removing system power or stopping the control application—an essential feature for maximizing system availability.

Unlock Mechanism: Release the ejector tabs at the top and bottom of the module fascia using the designated release key.
Alignment: Carefully align the T8191 module with the top and bottom guide rails of the intended chassis slot.
Insertion: Push the module straight back into the chassis until the rear connector seats firmly into the backplane.
Locking: Close the top and bottom module ejector tabs entirely until they click into their locked positions. Do not force the module; if it meets heavy resistance, remove it and check for pin alignment.

FAQs
