Honeywell MU-NTAP04 51201395-100 4 Port UCN Breakout Kit

Product Introduction

The Honeywell MU-NTAP04 51201395-100 4-Port UCN Breakout Kit is an essential communication accessory within Honeywell’s TDC 3000 and TPS (TotalPlant Solution) distributed control system architecture. Specifically designed for Universal Control Network (UCN) environments, the MU-NTAP04 provides a convenient and secure way to connect up to four devices or nodes to a single UCN cable segment.

It is a plug-in, DIN-rail mountable breakout interface that simplifies network expansion, system modifications, and field diagnostics by offering individual connection ports for multiple UCN nodes such as Network Interface Modules (NIMs), Process Managers, and Logic Managers. With robust isolation, reliable signal distribution, and tool-less installation, this kit plays a critical role in maintaining communication integrity across the Honeywell control system ecosystem.

Product Specifications

Product Applications

The MU-NTAP04 breakout kit is extensively used in Honeywell control system environments that rely on UCN for real-time communication between system nodes. Specific use cases include:

• UCN Node Expansion: Connects up to four devices, such as HPMs (High-Performance Process Managers) or NIMs (Network Interface Modules), to the same UCN bus.

• System Troubleshooting: Allows technicians to easily isolate and monitor individual communication links within the UCN.

• Field Testing: Provides a tap point for connecting diagnostic equipment or temporary test nodes.

• Network Redesign or Retrofit: Useful when modifying existing control networks without affecting the entire system.

• Segmenting UCN Devices: Ensures clean separation and easy disconnection for maintenance purposes.

Product Advantages

• Efficient Network Distribution: Supports up to four UCN connections from a single bus location, reducing cabling complexity.

• High Signal Integrity: Maintains signal quality through impedance-matched, shielded BNC connectors.

• Passive and Non-Intrusive: The breakout kit introduces no delay or processing overhead in the UCN communication stream.

• Easy Installation: DIN-rail mounting and plug-in connectors simplify system integration and maintenance.

• Honeywell Native Integration: Fully supported within the Honeywell TDC and TPS infrastructure.

• Field Proven Reliability: Built to Honeywell’s industrial-grade quality standards, ensuring durability in demanding conditions.

• Ideal for Diagnostics: Allows engineers to inject, monitor, or isolate signals without shutting down the system.

FAQ

1. Can the MU-NTAP04 be used with non-Honeywell twinaxial cables?
   It is strongly recommended to use Honeywell-specified RG-62/U cables to maintain signal integrity and ensure impedance compatibility.

2. Does this kit offer any internal signal amplification?
   No, the MU-NTAP04 is a passive breakout module and does not amplify signals.

3. Is there electrical isolation between each port?
   The ports are passively isolated in terms of physical routing, but not electrically isolated; grounding practices must be followed.

4. What is the impedance of the BNC connectors?
   All BNC connectors are 75 Ohm to match UCN cable standards.

5. Can this module be used in trunk/drop topologies?
   Yes, it supports both bus and trunk/drop configurations as used in UCN designs.

6. Are the connectors hot-swappable?
   While the device is passive, disconnection or connection should occur under maintenance conditions to avoid signal disturbance.

7. Does the MU-NTAP04 support redundancy?
   Redundancy is not built-in, but the breakout allows for redundant physical pathways through cabling design.

8. Is it possible to monitor signal integrity through this breakout kit?
   Yes, external diagnostic tools can be attached to individual ports for monitoring or testing.

9. Does the kit require a power supply?
   No power is required. It is a completely passive breakout device.

10. How does this module handle shielding and grounding?
    It has a metal housing and grounding paths to ensure minimal EMI and proper signal shielding.
