Product Overview
The Invensys Triconex 7400166-390, paired with termination board 9662-610NJ, is a high-reliability Fail-Safe Digital Output (FSDO) module for TMR (Triple Modular Redundant) safety systems. It delivers 8 independent fail-safe outputs using Form C relays, ensuring safe default states during faults or power loss. The termination board provides isolated, secure wiring between the module and field devices, supporting diagnostics and reliable signal routing. These components are certified SIL 3 under IEC 61508, making them ideal for Emergency Shutdown Systems (ESD), Fire & Gas Systems, and Safety Instrumented Systems (SIS) in oil & gas, chemical, and power generation industries.
