Triconex 4200 – Triple Redundant Safety Processor Module for Triconex Systems

In stock

Product Introduction:
The Triconex 4200 is the central processing unit (CPU) of the Triconex Safety Instrumented System. This is the “brain” of the entire safety system, executing the safety logic, processing all I/O data, and making the critical decisions that determine whether to trip the plant or keep it running. The “4200” designation identifies it as the main processor module in the Triconex family. It contains three independent 32-bit processors that execute the same safety program in lockstep, comparing results every millisecond. This TMR architecture ensures that a single point of failure (whether hardware or software) never leads to a spurious trip or a failure to trip. The 4200 is SIL 3 certified and is the heart of every Triconex safety system deployed worldwide.

Functional Features:
Triple Modular Redundancy: Three processors execute identical code simultaneously. If one disagrees, it is automatically taken out of service without affecting the safety function.
Deterministic Scan: Every safety loop executes at a guaranteed, fixed interval (e.g., every 50ms), ensuring predictable response times.
Online Logic Download: Safety logic can be modified and downloaded while the system is running (with proper safety procedures), minimizing downtime.
Event Logging: Records every trip event, alarm, and state change with millisecond timestamps for forensic analysis.
Dual Ethernet Ports: Provides redundant connection to engineering workstations and HMI displays.
Watchdog Timers: Multiple hardware watchdogs reset the processors if they hang, ensuring automatic recovery.
Battery Backup: Maintains program and data in RAM during a power failure for up to 72 hours.
