I/O modules

Product Overview

The ICS Triplex T8461C Trusted® Digital Output Module delivers reliable performance for safety-critical automation. It supports up to 40 field devices and uses a Triple Modular Redundant (TMR) design to enhance fault tolerance. The module continuously monitors current and voltage across each channel, ensuring accurate diagnostics and preventing failures such as stuck-on or stuck-off outputs.

Engineers benefit from built-in Sequence of Events (SOE) reporting with a resolution of 1 millisecond. The outputs are organized into isolated groups of eight, offering better separation and reliability. Front-panel LEDs provide real-time status for channels and module health, while hot-swap capability reduces downtime during maintenance.

Key Features

• 40 TMR Output Channels supporting redundancy and fault tolerance.
• Comprehensive Diagnostics with real-time monitoring for short and open circuits.
• Galvanic Isolation rated at 2500V impulse withstand.
• Overcurrent Protection for each channel, eliminating external fuse requirements.
• SOE Reporting with 1 ms accuracy for precise event capture.
• Hot Swap Functionality via Companion Slot or SmartSlot configurations.
• TÜV Certified SIL3 compliance with IEC 61508 standards.
• Isolated Power Groups in sets of eight for increased reliability.
