Product Overview

The TRICONEX 4400 is a Safety Manager Module (SMM) designed for Tricon safety systems and Honeywell TDC 3000 Universal Control Network (UCN) integration.

Unlike the Tricon 4328 and 4329 Network Communication Modules, which provide Ethernet-based network communication, the 4400 SMM is specifically intended to interface the Tricon system with Honeywell’s UCN. Its primary role is to allow the Tricon safety system to communicate process information and diagnostics to the Honeywell TDC 3000 environment.

The module is associated with Tricon Version 8 hardware. A Triconex hardware lifecycle document identifies Model 4400 as the “Tricon Safety Manager Module (Honeywell UCN Interface), version 8.”

This makes the 4400 particularly relevant for maintenance of legacy Tricon installations that still depend on a Honeywell TDC 3000 control architecture.

Technical Specifications

Main Function

The 4400 SMM was developed for communication between a Tricon safety system and Honeywell’s TDC 3000 Universal Control Network.

The SMM allows the UCN to recognize the Tricon as a safety node. It can transfer Tricon process information and diagnostic information to the Honeywell control environment, allowing operators to access safety-system information from the TDC 3000 system.

This is different from the function of a conventional Ethernet network communication module.

For reference:

• 4400 — Safety Manager Module, Honeywell UCN interface
• 4328 — Network Communication Module, Tricon Version 8
• 4329 — Network Communication Module, later Tricon versions
• 4329G — GPS-enabled Network Communication Module

The Triconex lifecycle documentation clearly separates these module types.

Typical Applications

The 4400 can be used in legacy industrial control installations where a Tricon safety system communicates with a Honeywell TDC 3000 DCS.

Typical applications include:

• Emergency shutdown systems
• Process safety systems
• Oil and gas facilities
• Petrochemical plants
• Refining installations
• Chemical processing
• Power generation
• Legacy Honeywell TDC 3000 environments
• Tricon Version 8 maintenance and spare-parts programs

For facilities maintaining an older Tricon/TDC 3000 architecture, keeping a compatible SMM available can be useful when communication hardware becomes difficult to source.

Installation and Configuration

Before replacing an existing SMM, verify the complete Tricon system configuration and hardware revision.

Recommended procedure:

1. Record the model and revision information from the existing module.
2. Confirm that the existing system uses a Honeywell TDC 3000 UCN interface.
3. Verify that the Tricon system version is compatible with the replacement module.
4. Photograph cable connections before removing the original module.
5. Follow the applicable Triconex maintenance and shutdown procedure.
6. Use ESD protection when handling the module.
7. Install the replacement in the correct chassis position.
8. Reconnect communication wiring according to the system documentation.
9. Check module status and diagnostic indicators after startup.
10. Confirm communication between the Tricon safety system and the Honeywell control system.

Because this is a safety-system communication component, replacement should be performed by personnel familiar with the installed Tricon and Honeywell system.

Inspection and Maintenance

For a New Open Box unit, inspect the module before installation.

Check:

• Front-panel condition
• PCB and housing condition
• Connector condition
• Pin alignment
• Identification labels
• Hardware revision
• Signs of corrosion or oxidation
• Evidence of previous installation or testing

Keep the module in ESD-safe packaging during storage and transportation.

For an installed system, module diagnostics and communication status should be checked as part of the site’s normal preventive-maintenance program.

Compatibility Notes

The most important point when sourcing this module is to avoid confusing the 4400 with the 4328/4329 Network Communication Modules.

The 4400 is an SMM for Honeywell UCN communication, while the 4328/4329 are identified as Network Communication Modules (NCMs).

Therefore, a 4328 or 4329 should not be treated as an automatic replacement for a 4400 simply because all three are communication-related Tricon modules.

For a replacement order, match:

• Model number
• Hardware revision
• Tricon system version
• Honeywell interface requirements
• Existing communication architecture
• Firmware requirements

Condition Information

The referenced eBay listing identifies this particular unit as New – Open Box rather than Used or Refurbished. eBay describes this condition as an item in excellent new condition that may have been opened, tested, or removed from original packaging.

The listing also identifies the brand as TRICONEX and the model as 4400.

Ordering Information

When requesting a quotation, use the complete identification:

TRICONEX 4400 Safety Manager Module (SMM)

If possible, provide a photograph of the original module label and the Tricon chassis configuration. This is especially important for older Version 8 systems where hardware and firmware revisions can affect compatibility.
