TC-303-02-4MO Trusted TMR Interface Module by ICS Triplex

Product Description

Product Overview

TC-303-02-4MO is a communication and termination module designed for the ICS Triplex Trusted® Triple Modular Redundant (TMR) safety system. It provides reliable data exchange and signal termination between Trusted® controller chassis and associated I/O subsystems.

The module is engineered to maintain synchronization, redundancy, and deterministic communication required in high-integrity safety and process control environments.

Functional Description

The TC-303-02-4MO module performs the following core functions within Trusted® TMR architectures:

• Communication interface between controller chassis and I/O subsystems

• Termination of shielded communication cables

• Support for TMR synchronization and fault-tolerant data transmission

• Maintenance of system integrity under single-channel or path failure conditions

The module is a passive yet critical component in ensuring continuous system availability.

System Compatibility

• Trusted® TMR Controllers

• Trusted® TMR I/O Subsystems

• Trusted® Safety Instrumented Systems

The TC-303-02-4MO operates exclusively within the Trusted® platform and is not compatible with non-Trusted systems.
