ICS Triplex T8403C Module 40-Channel Triple Redundant I/O

ICS Triplex T8403C Module 40-Channel Triple Redundant I/OProduct Description Triple Modular Redundancy for Critical Safety Logic The T8403C (Model: T8403C) is a high integrity 24V DC digital input module designed for the Rockwell Automation ICS Triplex Trusted system. Engineered for Safety Instrumented Systems (SIS), the T8403C (Catalog Number: T8403C) utilizes a Triple Modular Redundant (TMR) architecture to provide the highest levels of fault tolerance and system availability. Each of the 40 input

This protection allows for reliable operation in corrosive atmospheres (Class G3 per ISA S71

driving actuator current downward during an overspeed tracking event to enforce a default mechanical safe-state

This hardware serves as a dedicated energy bridge

DeviceNet Node Capacity: 63 Slave Nodes (Nodes 0–63

original factory-sealed Series C components

This eliminates the need for manual safety proof-testing cycles in many applications

Wiring Separation Constraints: Route the 2

The 5501-429 (Model: 5501-429) is a high-integrity power supply module engineered specifically for the Woodward MicroNet™ TMR (Triple Modular Redundant) digital control system

The industrial-grade components and thermal-efficient PCB allow for continuous operation up to +60 °C
