ICS Triplex TC-304-01 Remote Expansion Cable

The ICS Triplex TC-304-01 serves as a remote I/O termination and simulation unit within Trusted® Regent control architectures. It provides a fully wired interface between field devices and Companion Slot modules—including digital input (DI), analog input (AI), and digital output (DO) types. This assembly simplifies commissioning, troubleshooting, and maintenance in high-integrity industrial environments.

Unlike standard cabling, the TC-304-01 integrates power distribution, signal termination, and simulation circuitry into a single portable unit. It supports AC input voltage ranging from 100 V to 240 V at 50/60 Hz, ensuring global compatibility. The unit also includes built-in test points that allow engineers to simulate up to 60 field signals without external equipment.

Physical and Logistics Data

Integration and Operational Use

Engineers typically deploy the TC-304-01 during system startup, periodic validation, or emergency maintenance. Because it replicates real-world I/O behavior through onboard simulation, technicians can verify controller logic without disconnecting field wiring. This capability significantly reduces downtime in sectors such as oil and gas, nuclear power, and chemical processing.

Moreover, the dual Ethernet interfaces enable simultaneous connection to both a local engineering workstation and the plant network. As a result, remote diagnostics and firmware updates remain possible even during testing phases. The flight-case design further enhances field readiness, allowing safe transport between control rooms, skids, or remote sites.
