ICS TRIPLEX T8312-4 Trusted TMR Expander Interface Adapter Unit

The Trusted® Processor is the main processing component in a Trusted System. It is a powerful,

user-configurable module providing overall system control and monitoring facilities and processes

input and output data received from a variety of analogue and digital Input / Output (I/O) modules

across a Trusted TMR Inter-Module Communications Bus.

The range of applications for the Trusted TMR Processor vary in integrity level and include fire and

gas control, emergency shutdown, monitoring and control, and turbine control.

Features:

• Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation.

• Hardware Implemented Fault Tolerant (HIFT) architecture.

• Dedicated hardware and software test regimes which provide very fast fault recognition and

response times.

• Automatic fault handling without nuisance alarming.

• Time-stamped fault historian.

• Hot replacement (no need to re-load programs).

• Full suite of IEC 61131-3 programming languages.

• Front panel indicators that show module health and status.

• Front panel RS232 serial diagnostics port for system monitoring, configuration and

programming.

• IRIG-B002 and 122 time synchronisation signals (available on T8110B only).

• Active and Standby processor fault and failure contacts.

• Two RS422 / 485 configurable 2 or 4 wire connections (available on T8110B only).

• One RS485 2 wire connection (available on T8110B only).

• TϋV Certified IEC 61508 SIL 3.
