PLC Autocontroller, located in Xiamen, China, has over 20 years of experience supplying industrial automation spare parts.
We offer core automation components from top global brands. The TRICONEX 4351A communication module is designed specifically for Triconex systems, ensuring real-time, reliable data exchange and system interconnection for distributed industrial control and safety systems.
1. Core Role
4351A = Tricon TMR → 3× isolated RS-485/RS-422/RS-232 in parallel.
Each port runs its own protocol taskmaster; lose one, the other two stay on-line.
Built-in 2 kV isolation & 600 W surge stopper – no external converters needed.
2. Speed & Load
Baud 300 – 115 k, jumper-free auto-detect.
4 kB onboard cache per port = 256 frames of 16 bytes @ 19.2 k = 133 ms ride-through if host polls late.
Broadcast, multi-drop or point-to-point – configure via TriStation 1131 drag-and-drop.
