TRICON 3700A Modular PLC System
This control system handles mission-critical operations where failure isn’t an option. We’ve seen it deployed in offshore drilling platforms managing complex valve sequencing, chemical plants monitoring reactor temperatures, and power stations regulating turbine operations. Its triple-redundant architecture keeps production lines running even during component failures.

Industrial Applications
Engineers specify this system when human safety and continuous operation are paramount. In a recent Middle East gas facility, it maintained pipeline pressure regulation despite ambient temperatures hitting 55°C. The modular design supports hot-swapping components – a client in Texas replaced a faulty communication card during live production without shutdown.
Common configurations include:
- 3703X for burner management systems
- 3720 with SIL 3 safety ratings
- 4351B analog input modules
- 3805E output modules with diagnostics
- 8312 communication gateways
Our Support
We maintain active stock across 16 warehouses in 6 countries. When a Norwegian client needed emergency replacement for a 3703X module, we dispatched from Amsterdam to Oslo in 18 hours. Every part carries our standard 1-year warranty covering defects and performance issues.
