        Features:

        • Direct Rear-Mount Serial Communication Gateway for TMR Processors
        • Facilitates Modbus Master Operation and Inter-System Peer to Peer Messaging
        • Integrates Optional IRIG-B Time Synchronization Signal Routing

        The ICS TRIPLEX T8123C serves as the Processor Interface Adaptor attached directly to the rear of a TMR processor, delivering robust serial connectivity to remote automation equipment. It maintains three independent RS422/485 communication links that enable deterministic data transfer between the Trusted TMR processor and external distributed control devices. The T8123C empowers the system to function as a Modbus master, allowing direct management and data polling of slave devices throughout the serial network. Beginning with Toolset version 3.5, the T8123C also supports Peer to Peer communications between separate Trusted systems, substantially enhancing distributed architecture flexibility. Furthermore, the adaptor includes provision for connecting IRIG-B time synchronization signals directly to the processor, ensuring precise time alignment for event sequencing and coordinated system operations.

        The T8123C provides fundamental communication services essential to the complete Trusted rack, acting as a critical gateway that directly impacts the reliable exchange of process data and supervisory commands. One T8123C adaptor is required for each TMR processor that must communicate with remote serial systems, and it is always mounted in the dedicated rear position immediately behind the processor module. This direct-attachment configuration conserves rack space while guaranteeing secure, vibration-resistant physical and electrical integration with the TMR processor.

        For time-critical safety applications, the T8123C routes external IRIG-B timing references straight to the processor, enabling millisecond-accurate event logging and synchronized operational timestamps across the entire installation. In expanded system deployments, utilizing Toolset version 3.5 or newer unlocks Peer to Peer messaging capabilities between Trusted systems equipped with the T8123C. The adaptor continually supervises the health of its three RS422/485 serial interfaces, maintaining configured baud rates and line parameters to ensure uninterrupted communication. If disturbances affect one serial channel, the remaining independent links sustain overall network connectivity, preserving data flow and system availability.
        The T8123C 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 T8123C Processor Interface Adaptor is a specialized communication component designed to connect directly to the rear of a Triple Modular Redundant (TMR) Trusted processor. By establishing this direct physical and electrical connection, the T8123C acts as a critical bridge between the core safety processor and external network environments. The primary function of the T8123C is to provide a dedicated communications connection interface, allowing the TMR processor to seamlessly interact with remote systems through three independent serial RS422/RS485 links.

        This T8123C Processor Interface Adaptor is specifically engineered to handle the problem of secure, high-integrity data isolation and multi-protocol communication connectivity in safety-critical environments. It resolves the challenge of safely exporting diagnostic and operational data from a fault-tolerant safety system to third-party control networks without compromising the integrity of the primary control loop. Furthermore, the T8123C expands system capability by enabling the main system to act as a Modbus master and, from Toolset version 3.5 onwards, supports robust Peer-to-Peer communications directly between multiple Trusted systems. It also features the option to connect IRIG-B time synchronization signals directly to the processor, resolving millisecond-level time-stamping discrepancies across distributed networks.

        The T8123C Processor Interface Adaptor is widely applied in high-reliability industrial automation sectors, such as Emergency Shutdown (ESD) systems, Fire and Gas (F&G) detection networks, and critical Turbomachinery Control (TMC) in the oil and gas, petrochemical, and power generation industries. For installation and integration, the T8123C must be securely mounted onto the rear of the designated TMR processor chassis, ensuring all serial cabling is properly shielded to maintain signal integrity in high-EMI environments. When considering lifecycle upgrades, facilities utilizing older toolset versions should upgrade to Toolset version 3.5 or higher to fully unlock the inter-system Peer-to-Peer capabilities of the T8123C, while older serial architectures can be systematically integrated into modern Ethernet topologies using compliant serial-to-Ethernet gateways.
