ICS Triplex T8480C Trusted TMR Digital Output Module

The ICS Triplex T8480C is a high-availability Triple Modular Redundant (TMR) module designed for the Trusted® platform. It provides 40 independent output channels for mission-critical industrial safety systems. The module utilizes a voting architecture across three internal processors to ensure continuous operation. This design allows the system to identify and mitigate hardware faults without interrupting the process. It meets SIL3 safety requirements according to IEC 61508 standards.

Diagnostic Monitoring and Field Wiring Safety

Each channel on the T8480C features comprehensive diagnostic capabilities to ensure field-side integrity. The module monitors for open and short circuits in real-time. It includes 2500V opto-galvanic isolation to protect internal electronics from external surges. Outputs are divided into groups of eight channels. Each group provides individual overcurrent protection. This feature eliminates the need for external fusing and simplifies cabinet wiring.

High-Resolution Event Tracking and Hot-Swap Support

The T8480C supports Sequence of Events (SOE) reporting with a resolution of 1ms. This allows for precise chronological logging of all state changes. Maintenance teams can use these timestamps for accurate post-fault analysis. The module supports hot-swapping through SmartSlot configurations. You can replace the hardware during active operation to maintain zero system downtime. Front-panel LEDs provide immediate feedback on channel health and module status.
