        Features:

        • Operates at a high-speed communication rate of 10 Megabits per second (10 Mbps) over standard IEEE 802.3 networks.
        • Equipped with dual BNC ports supporting standard RG58 50-ohm thin coaxial cabling for reliable signal transfer.
        • Integrated with 500 VDC galvanic port isolation to safeguard internal logic circuitry against external grid disturbances.
        This original Schneider Electric Triconex 4329 Network Communication Module (NCM) is available as factory-new surplus, certified pre-owned, or fully tested refurbished stock ready for deployment. Each module undergoes comprehensive physical and hardware diagnostic inspections to ensure full adherence to original factory specifications prior to shipment.

        Designed for high-availability Tricon TMR architectures, this module bridges safety instrumented chassis with external Ethernet networks using standard TSAA protocol messaging. It handles critical network telemetry and host integration while leaving core safety logic processing unburdened and fully isolated.

        When integrating into active Tricon racks, note that two modules can reside within a single logical slot to function as independent dual communication paths rather than hot-spare redundant units. Proper mechanical keying must be observed during insertion, and coaxial cabling runs should comply with standard RG58 impedance and distance requirements.
        The Triconex 4329 Network Communication Module is fully supported with global stock availability and direct supply service provided by the manufacturer (OEM) distributors.
        Invensys Schneider Triconex 4329 Manuals, Datasheets, and Links Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Serves as the central network interface in Emergency Shutdown Systems (ESD) requiring real-time sequence of events telemetry.
        • Provides continuous communication networking for industrial Fire and Gas (F&G) monitoring platforms across process facilities.
        • Enables secure Ethernet connectivity in critical Turbomachinery Control Systems (TMC) for high-speed parameter monitoring.
        • Rated to maintain a full power output capacity of 175 Watts at operating ambient temperatures up to 140°F (60°C).
        • Available with factory conformal coating option (model designation 4329C) for enhanced protection in harsh industrial environments.
        • Certain conformal-coated configurations hold official hardware certification for safe operation within demanding marine environments.
        • Designed for integration into Triple Modular Redundant (TMR) systems to maintain safety integrity without interfering with main processing loops.
        • Constructed with custom backplane mechanical keying in each slot to prevent accidental installation into improper module positions.
        • Maintains total galvanic separation between external host networks and internal system logic through a 500 VDC isolation barrier.
        • Fully compatible with Tricon controller system firmware versions v9 through v10 architecture specifications.
        • Supports native hardware upgrade to model 4329G for applications requiring GPS-based precision time synchronization functionality.
        • Communicates seamlessly with TriStation 1131 software for system configuration, project downloads, and online diagnostic telemetry.
        Description
        Schneider Triconex 4329 Network Communication Module operates as a dedicated gateway for Tricon Triple Modular Redundant systems to communicate across standard Ethernet networks. The first network port (NET 1) handles peer-to-peer messaging and precision time synchronization protocols strictly between Tricon controllers on isolated safety networks. Integrated RS-232 communication alongside dual 15-pin D-connectors expands physical layer connectivity while 500 VDC port isolation protects critical control backplanes from field power surges.

        Engineered for IEEE 802.3 standards at 10 Mbps transmission rates, the Triconex 4329 module utilizes standard RG58 50-ohm coaxial cable for local network runs reaching up to 607 feet (185 meters). Extended plant architectures can stretch up to 2.5 miles (4,000 meters) by incorporating fiber-optic repeaters or thick-net infrastructure. The secondary network port (NET 2) supports open network connections to host applications including TriStation 1131, Sequence of Events software, OPC servers, and DDE server platforms.

        Designed for emergency shutdown, fire and gas detection, and turbomachinery control applications, the Triconex 4329 NCM receives data updates from Main Processors once per scan cycle. Front-panel diagnostic LEDs provide continuous visual tracking for PASS, FAULT, and ACTIVE states, with individual transmit and receive indicators for each channel. Two 4329 modules can occupy a single logical chassis slot to function as independent channels without operating as active hot-spare modules.

        Technical notes
        Installing dual Triconex 4329 modules in a single logical slot provides independent dual-channel operation rather than hot-spare redundancy, requiring Alias numbers for host variable access.

        VIEW ALL FAQS
        What are the primary differences between NET 1 and NET 2 ports on the Triconex 4329?
        NET 1 on the Triconex 4329 is dedicated to Peer-to-Peer and Time Synchronization protocols between safety networks of Tricon controllers, while NET 2 supports open networking to external hosts and host applications like TriStation 1131, SOE, and OPC servers.
        How often is communication data refreshed on the Triconex 4329 module?
        Data on the Triconex 4329 module is typically refreshed by the Tricon Main Processors once per scan cycle.
        What types of physical connectors are built into the Triconex 4329 module?
        The Triconex 4329 module features two BNC connectors for thin-net coaxial cables, two 15-pin D-connectors for external self-powered transceivers, and one RS-232 serial port.
        Does the Triconex 4329 support hot-spare redundancy when installing two modules in a single slot?
        No, when two Triconex 4329 modules reside in one logical slot of the Tricon chassis, they function independently as dual communication channels rather than hot-spare modules.
        How do external hosts obtain read and write access to variables via the Triconex 4329?
        External hosts can only read or write data to Tricon system variables that have assigned Alias numbers configured through the Triconex software environment.
        How can I request pricing, availability, and lead time for a replacement Triconex 4329 module?
        You can request a quote for new surplus, pre-owned, or certified refurbished Triconex 4329 modules by submitting an inquiry directly through our website quotation form or emailing our sales engineering team.
