ICS Triplex T8111 is a fault-tolerant main processing component designed for the Trusted system architecture. Operating in a Triple Modular Redundant (TMR) lock-step configuration across three independent Processor fault containment regions (FCRs), the T8111 executes user-defined application programs, performs system monitoring, and manages I/O data exchanges across the triplicated Inter-Module Bus. The module integrates two configurable RS422/485 serial ports, one dedicated RS485 2-wire serial port, an RS232 front panel diagnostic interface, and built-in IRIG-B time synchronization capabilities. The ICS Triplex T8111 is designed for critical safety instrumented functions and process control applications requiring high availability and fault isolation.
