Overview

The ICS TRIPLEX T8451 is a TrustedTM TMR 24 Vdc Digital Output Module designed for safety-critical applications that demand high reliability and continuous operation.

Key Features

• Triple Modular Redundancy (TMR): Employs three independent internal channels for each output, ensuring operation even if one channel fails.
• 40 Digital Outputs: Controls up to 40 external devices, grouped into five sets of eight outputs each.
• 24 Vdc Operation: Operates on a 24 Vdc power supply with a range of 20 to 32 Vdc.
• Fault Tolerance: TMR design and comprehensive diagnostics continuously monitor for faults and isolate them to prevent system failures.
• Line Monitoring (Optional): Optional configuration enables monitoring individual output lines for open circuits, short circuits, and other issues with connected devices.

Safety Features

• High Isolation: Built-in opto/galvanic isolation barriers protect the module from external electrical noise and surges.
• Automatic Over-current Protection: Each channel has individual protection, eliminating the need for external fuses.
• Sequence of Events (SOE) Reporting: Tracks and records critical events with a 1 millisecond resolution, aiding in troubleshooting and incident analysis.
• Hot-Swappable: Allows for module replacement while the system is running (hot-swapping) using a dedicated companion slot or a smart slot configuration.

Operating Environment

• Temperature: -5°C to 60°C (23°F to 140°F)
• Humidity: 5 – 95% RH non-condensing
