Product advantages

Triple Modular Redundancy (TMR): Ensures high reliability by using three independent input circuits per channel, with fault detection and voting mechanisms to maintain system integrity even if one input channel fails.

Conformal Coating: The module is coated to withstand harsh environmental conditions, enhancing its durability and reliability in challenging environments.

SIL3 Certification: Complies with SIL3 standards, making it suitable for safety-critical applications where system reliability is paramount.

Advanced Diagnostics: Provides real-time monitoring and diagnostics to detect and report faults in input channels, helping to ensure continuous operation and support predictive maintenance.

High Reliability: Designed for industries requiring robust and reliable digital input solutions.

Components

Field termination unit (FTU)

The Field Termination Unit (FTU) is the section of the I/O Module that connects all three FIUs to a single field interface. The FTU provides the Group Fail Safe Switches and passive components necessary for signal conditioning, over-voltage protection, and EMI/RFI filtering.

Field interface unit (FIU)

The Field Interface Unit (FIU) is the section of the Module that contains the specific circuits necessary to interface to the particular types of field I/O signals. Each Module has three FIUs, one per slice. For the TMR 24 Vdc Digital Output Module, the FIU contains one stage of the output switch structure, and sigma-delta (ΣΔ) output circuit for each of the 40 field outputs.

Host interface unit (HIU)

The HIU is the point of access to the Inter-Module Bus (IMB) for the Module. It also provides power distribution and local programmable processing power. The HIU is the only section of the I/O Module to directly connect to the IMB Backplane. The HIU is common to most high integrity I/O types and has type dependent and product range common functions.

Application

FAQ

Q: What is an ICS Trusted TMR module?

A: An ICS Trusted TMR module is a safety-critical control component based on Triple Modular Redundancy (TMR) architecture, designed to ensure high availability and fault tolerance in industrial safety systems.

Q: What does TMR (Triple Modular Redundancy) mean in this context?

A: TMR refers to a system design where three independent processing channels operate in parallel, with a majority-voting mechanism to ensure accurate and reliable outputs even if one channel fails.

Q: What are the main applications of ICS Trusted TMR modules?

A: These modules are commonly used in emergency shutdown systems (ESD), fire and gas systems (F&G), and other safety instrumented systems (SIS) in high-risk industries.

Q: Which industries typically use ICS Trusted TMR systems?

A: Key industries include oil & gas, petrochemical, power generation, and other process industries where safety and system uptime are critical.

Q: What are the key advantages of ICS Trusted TMR modules?

A: The main advantages include high fault tolerance, continuous operation without interruption, improved safety integrity, and reduced risk of system failure.

Q: Are ICS Trusted TMR modules compliant with international safety standards?

A: Yes, they are designed to meet stringent safety standards such as IEC 61508 and are suitable for SIL-rated safety applications.

Q: How do ICS Trusted TMR modules handle faults?

A: The system automatically detects faults in any of the three channels and isolates the faulty channel while maintaining normal operation using the remaining channels.

Q: Can ICS Trusted TMR modules be integrated with existing control systems?

A: Yes, they are designed for integration with Distributed Control Systems (DCS), PLCs, and other industrial automation platforms via standard communication interfaces.

Q: What types of I/O modules are available in the ICS Trusted system?

A: The system supports a wide range of I/O modules, including digital input/output, analog input/output, and specialized modules for safety applications.

Q: What is the typical lifecycle support for ICS Trusted TMR modules?

A: Vendors typically provide long-term lifecycle support, including spare parts, technical assistance, firmware updates, and system upgrades.

Q: How does the voting mechanism work in a TMR system?

A: Each of the three channels processes the same input independently, and the system uses a 2-out-of-3 voting logic to determine the correct output, ensuring reliability even in the event of a single failure.

Q: What maintenance is required for ICS Trusted TMR modules?

A: Routine diagnostics, periodic testing, and firmware updates are recommended to ensure optimal performance and compliance with safety requirements.

Q: Are ICS Trusted TMR modules suitable for hazardous environments?

A: Yes, many modules are certified for use in hazardous areas and are designed to operate reliably under harsh environmental conditions.

Q: What should buyers consider when selecting an ICS Trusted TMR module?

A: Key factors include system compatibility, required SIL level, I/O capacity, environmental conditions, and vendor support capabilities.

Q: Why choose ICS Trusted TMR over standard PLC systems?

A: ICS Trusted TMR systems provide significantly higher safety integrity and fault tolerance, making them ideal for critical applications where failure is not an option.
