PLC Autocontroller, 20 years moving automation from our warehouse to your rack
1. 30-Second Snapshot
Triple-module redundancy does not stop at the main rack.
The Triconex 4210 Remote Extender pair (primary + remote) carries the full TMR I/O bus up to 12 km on single-mode fiber while keeping SIL 3 integrity.
We keep the complete 4210-3 kit (three primary + three remote modules, cables & mounting ears) on the shelf in Xiamen, ready for same-day DHL/FedEx/UPS export.
2. Why You Still Meet “4210” in Every P&ID
Distance: 12 km point-to-point, no repeaters.
Speed: 375 kbps deterministic, jitter <1 µs.
Noise: fiber = 0 EMI; 4 kV isolation between racks.
Scale: one primary group feeds up to 3 remote nodes.
Legacy-proof: identical part since Tricon v9, v10 & v11.
