TRICONEX 4352B｜Communication Module｜
The Triconex 4352B is a high-reliability communication module designed for use in Triconex/Trident Safety Instrumented Systems (SIS). It serves as a key interface that enables robust, fault-tolerant communication between safety controllers and external networks, operator stations, DCS/SCADA, remote I/O, and other devices in mission-critical industrial environments.
Key Technical Features
Communication Interfaces
Ethernet: Dual fiber-optic Ethernet ports (typically 100 Mbps each) and optional copper 10/100 Mbps ports for network connectivity.
Serial: Up to 4 × RS-232/RS-485 serial ports (DB-9) for connection to discrete devices or legacy equipment.
Protocol Support
Supports a variety of protocols including:
• TriStation (Triconex system protocol)
• Modbus (RTU/TCP)
• TCP/IP, ICMP, SNTP
• OPC, Peer-to-Peer communications, and more.
Redundancy & Fault Tolerance
Built-in TMR redundant communication paths with automatic failover.
Continuous health diagnostics and status monitoring.
Hot-swappable module design for online replacement without system shutdown.
Power & Environmental
Power Supply: 24 V DC (typical), with low consumption.
Operating Temperature: –40 °C to +70 °C (extended industrial range).
Robust industrial reliability with high isolation on communications ports.
Safety Certification
SIL 3 certified according to IEC 61508 functional safety standards, suitable for ESD, F&G, and other high-integrity safety applications.
Typical Applications
The 4352B module is widely used in industries where communication reliability and safety are critical, including:
Oil & Gas
• Offshore platforms and pipeline safety systems
