🧩 Functional Description
The TRICONEX 3625 module continuously monitors field-level digital signals such as emergency stop buttons, limit switches, valve status indicators, and safety interlocks. Each input is processed independently by three parallel logic paths. The module then performs a voting mechanism to determine the correct and safe state of the signal.
If a discrepancy occurs, the faulty channel is automatically identified and isolated without interrupting system operation. This behavior allows maintenance teams to address issues proactively while the safety function remains fully operational.
