TRICONEX 4500
Product Name
TRICONEX 4500 Highway Interface Module (HIM); TRICONEX TMR SIS Highway Interface Card (TRICONEX by Schneider Electric Process Safety).
Product Description
The TRICONEX 4500 is a rugged, fault-tolerant highway interface module engineered for TRICONEX TMR safety controllers and distributed I/O architectures. It acts as a critical gateway to connect TMR chassis, remote I/O racks, and external hosts, delivering deterministic data transfer for safety interlocks, emergency shutdown (ESD), and process control in harsh industrial environments.
Key features include redundant highway ports for fault-tolerant paths, hot-swappable design for online replacement without SIS downtime, and built-in diagnostics for rapid fault identification. It supports TRICONEX proprietary highway protocols for low-latency, synchronized data exchange across distributed safety loops, with TMR voting to eliminate single points of failure.
Compliant with IEC 61508 SIL 3 and built for industrial ruggedness, the 4500 is ideal for retrofits or expansions
of legacy TRICONEX TMR SIS where reliable, fault-tolerant highway communication is mandatory to protect personnel, equipment, and the environment.
