Features:

  • Direct Communications Link Between the TMR Processor and Remote Systems Through Three RS422/485 Serial Interfaces
  • Integrates External Data Exchange with IRIG-B Time Synchronization and Modbus Master Control
  • Functions with Trusted Toolset Version 3.5 and Higher to Enable Peer to Peer System Communications

The ICS TRIPLEX T8120C operates as the Processor Interface Adaptor for Trusted TMR processors, establishing the communications connection interface between the TMR processor and remote systems. The T8120C mounts directly to the rear of the TMR processor and provides three serial RS422/485 links for external system connectivity. The T8120C offers the option of connecting IRIG-B time synchronization signals to the processor for accurate time alignment. The T8120C additionally provides the ability of the system to become a Modbus master for direct integration with external control networks. As of Trusted Toolset version 3.5, the T8120C enables Peer to Peer communications between Trusted systems, expanding inter-system connectivity beyond earlier interface capabilities.

The T8120C provides essential communication interface functions for the Trusted safety system and is a critical component of the external data path, directly affecting proper communication between the TMR processor and remote equipment. One T8120C Processor Interface Adaptor is required per TMR processor to establish external serial communications. The T8120C connects directly to the rear of the TMR processor, utilizing the dedicated processor interface position.

For comprehensive external communication applications, the Trusted system employs the T8120C's three independent RS422/485 serial links to establish multiple pathways to remote systems. In addition to standard serial data transfer, the T8120C configuration supports IRIG-B time synchronization input for applications requiring precise event timing across the safety network. When operating with Trusted Toolset version 3.5 or above, the T8120C activates Peer to Peer communications between multiple Trusted systems, allowing direct data exchange without additional protocol conversion hardware. The T8120C manages Modbus master operations and serial link communications through the processor interface circuitry specified in the adaptor specifications.
The T8120C ICS TRIPLEX Processor Interface Adaptor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The ICS TRIPLEX T8120C Processor Interface Adaptor is a dedicated communication component that connects directly to the rear of a TMR processor. The T8120C provides a comprehensive communications connection interface between the TMR processor and remote systems via three serial RS422/485 links. Additionally, the T8120C offers the option of connecting IRIG-B time synchronization signals directly to the processor, ensuring accurate temporal alignment across the safety system. The T8120C also enables the system to become a Modbus master, allowing direct integration with external control devices and networks. Furthermore, the T8120C provides the ability of the system to support Peer to Peer communications between Trusted systems, a capability available as of Toolset version 3.5.

This processor interface adaptor is specifically designed to handle the challenge of establishing reliable, deterministic communication pathways in triple modular redundant safety architectures. The T8120C solves the critical problem of interfacing TMR processors with remote monitoring and control systems by providing robust serial communication links, thereby eliminating potential single points of failure in data transmission. By supporting IRIG-B time synchronization, the T8120C resolves timing coordination issues that could compromise event sequencing and diagnostic accuracy in high-integrity applications. The T8120C's Modbus master capability addresses integration complexities with third-party field devices and SCADA infrastructures, while its Peer to Peer communication support enables seamless data exchange between multiple Trusted systems without intermediate protocol conversion.

The T8120C is applied in industries demanding the highest levels of functional safety and continuous availability, including oil and gas production, chemical processing, power generation, nuclear facilities, and offshore platform automation. For installation and integration, the T8120C mounts directly to the rear of the TMR processor, ensuring secure physical and electrical connectivity within the Trusted chassis architecture; the three RS422/485 serial links should be configured according to project-specific network requirements, with IRIG-B connections established where precise time-stamping of safety events is required. Regarding upgrades, systems operating with Toolset versions earlier than 3.5 should be updated to fully unlock the T8120C's Peer to Peer communications capability, thereby ensuring complete utilization of the adaptor's feature set and maintaining compatibility with modern Trusted system deployments.
