We integrate Modbus protocol support for seamless communication with third-party devices and PLCs. TCP/IP and ICMP protocols enable standard network connectivity for enterprise-level data integration. The Triconex 4351B utilizes SNTP for precise time synchronization across distributed safety systems. TSAA with IP Multicast support facilitates efficient data distribution to multiple network nodes. We include Trimble GPS protocol for accurate time-stamping of safety events. Peer-to-peer UDP/IP communication enables direct module-to-module data exchange without a central server. The Triconex 4351B also supports Jet protocol for specialized Triconex communication requirements.

Key Technical Features

Comprehensive Port Configuration

We design the Triconex 4351B with four serial ports and two network ports for maximum connectivity flexibility. This configuration supports both legacy serial devices and modern Ethernet networks simultaneously. Consequently, you can integrate the safety system with existing infrastructure without protocol converters.

Robust Electrical Isolation

The module provides 500 VDC isolation between ports to prevent ground loop interference in complex installations. This isolation protects sensitive safety circuits from electrical noise and potential voltage differences. Therefore, you maintain signal integrity even in electrically noisy industrial environments.

Multi-Protocol Versatility

We equip the Triconex 4351B with support for TriStation, Modbus, TCP/IP, and numerous other industrial protocols. This versatility allows connection to diverse devices including HMIs, DCS systems, and enterprise networks. As a result, you achieve seamless data flow from the safety system to business systems.

Flexible Ethernet Connectivity

The module offers both copper and fiber Ethernet options operating at 10/100 Mbps speeds. Copper ports provide convenient connectivity for local networks while fiber supports long-distance installations. Subsequently, you can choose the physical medium that best suits your plant layout.
