Product Description

The T8403C is a high-integrity expander communication module for the Schneider Electric ICS Triplex Trusted TMR System safety control architecture.

This module provides secure communication between the main controller chassis and remote expansion chassis, enabling distributed I/O deployment while maintaining Triple Modular Redundant (TMR) safety integrity. It is designed for SIL 3-capable safety instrumented systems (SIS) requiring deterministic, high-reliability data exchange with hardware fault tolerance.

The T8403C processes communication through three independent voting paths (HFT=1) to ensure continuous operation even in the presence of hardware faults. It is widely used in mission-critical safety applications where system availability and data integrity are mandatory.

Frequently Asked Questions

Q1: Does it support hot-swapping?
Yes. The T8403C is designed for high-availability SIS environments and supports hot-swapping in redundant configurations without interrupting system operation.

Q2: How many expansion chassis can be connected?
The number depends on system I/O load and architecture design, but Trusted TMR systems typically support multiple expander modules for distributed safety networks.
