The ICS Triplex T8110 is a high-performance Trusted TMR Processor designed as the central intelligence for safety-instrumented systems.It utilizes Triple Modular Redundancy (TMR) to provide hardware-implemented fault tolerance, ensuring continuous operation for SIL 3-rated industrial processes.
Specifications
Processor Type:Dual Motorola PowerQUICC II in lock-step mode per channel.
Safety Rating:IEC 61508 SIL 3 compliant.
Memory:32 MB DRAM (Working) and 128 MB Flash ROM (Storage).
Operating Voltage:24 Vdc nominal (20 to 32 Vdc range).
Power Consumption:15.5 W typical; 18 W maximum.
Scan Time:Minimum 10 ms (application dependent).
Serial Communications:One RS232 and two RS422/485 ports.
Operating Temperature:-5°C to +60°C.
Features
Fault-Tolerant Architecture:Employs a triplicated processing environment where three identical sub-processors execute the same logic to eliminate single points of failure.
Majority Voting System:Uses hardware-based 2oo3 voting to verify data integrity across all processing channels before executing commands.
Hot Swap Capability:Supports the online removal and replacement of the processor module without shutting down the system or losing process control.
High-Speed Synchronization:Ensures all three processing paths are perfectly synchronized via a dedicated inter-processor communication link.
Self-Diagnostic Testing:Performs exhaustive background checks on internal memory, logic gates, and communication buses with over 99% fault coverage.
System Integration:Communicates directly with I/O modules via the triplicated Inter-Module Bus (IMB) for ultra-low latency data exchange.
Event History:Includes an internal non-volatile buffer for time-stamped sequence of events (SOE) and fault logging.
