ICS Triplex Trusted TC-302-02-4M0 Communication Interface

Product Description

Product Overview

TC-302-02-4M0 is a Trusted® Triple Modular Redundant (TMR) communication and termination module developed by ICS Triplex, part of the Honeywell Trusted® safety system portfolio.
It provides deterministic communication paths and secure termination between Trusted® controller chassis and I/O subsystems, ensuring system synchronization and fault tolerance.

This module is a core infrastructure component in high-availability safety and process control architectures.

Functional Description

Within a Trusted® TMR system, TC-302-02-4M0 performs the following functions:

• Communication interface between controller chassis and I/O subsystems

• Secure termination of shielded communication cables

• Support for TMR synchronization and redundancy logic

• Maintenance of system integrity during single-path or channel failures

The module does not perform control logic but is essential for reliable signal routing and redundancy enforcement.

System Compatibility

• Trusted® TMR Controllers

• Trusted® TMR I/O Subsystems

• Honeywell Trusted® Safety Instrumented Systems

The TC-302-02-4M0 operates exclusively within the Trusted® platform.
