Overview
The ICS Triplex T8191 is a single-slot width shield designed to protect I/O and communication modules in Trusted TMR systems. It ensures consistent environmental and physical protection, helping maintain reliable system operation under industrial conditions. Manufactured by Rockwell Automation, this module shield supports high-integrity automation applications where continuous performance and safety are critical.
Key Features
- Triple Redundancy: Three independent processors execute the same logic, so system integrity remains if one processor fails.
- Fail-Safe Operation: The T8191 drives the system into a safe state immediately when a fault occurs.
- Self-Testing: Continuous internal monitoring detects faults, and the system shuts down automatically when necessary.
- Safety Certification: Complies with IEC 61508 SIL 3 and EN 50128 standards, ensuring industrial-grade reliability.
