Description
Functional Features
• Triple Modular Redundant (TMR) architecture—three independent microprocessors vote on every input for SIL 3 fault tolerance
• Hot-swappable while system remains in operation
• Built-in self-test and line-monitoring detect open/short circuits on field wiring
• Sequence-of-Events (SOE) capture with 1 ms time-stamp resolution for post-event analysis
• Front-panel LEDs and backplane diagnostic registers for immediate fault indication
• Conformal-coated PCB for harsh-environment longevity
