What Is the ABB Bailey NTRL03 6637359K2?
The ABB Bailey NTRL03 6637359K2 is an NTRL Remote Link Terminal intended to provide an interface between compatible elements of an ABB Bailey industrial control system.
The terminal provides a defined physical connection point within the system architecture. Depending on the host configuration, remote link connections can allow control-system equipment to exchange signals or maintain connectivity with equipment installed at another location.
A simplified architecture can be represented as:
Control System → Remote Link Interface → NTRL03 → Remote System Equipment
The actual connection architecture depends on the ABB Bailey system in which the NTRL03 is installed.
Because industrial control systems can contain multiple terminal and interface assemblies with similar physical characteristics, the complete identification NTRL03 6637359K2 should be used when sourcing or replacing the component.
NTRL Remote Link Terminal Working Principle
The NTRL03 functions as an interface component within a remote connection architecture.
A remote link system generally requires a reliable physical interface between local control equipment and equipment located elsewhere in the system. The terminal provides an organized point for these connections, helping route the relevant signals between the associated system sections.
A generalized connection can be represented as:
Local Control Equipment
↓
Local Interface
↓
NTRL03 Remote Link Terminal

Remote Control / I/O Equipment
The terminal itself should not be confused with a programmable controller. Its primary purpose is to support the physical and electrical interconnection required by the larger control-system architecture.
Role in ABB Bailey Distributed Control Systems
Distributed control architectures divide system functions among multiple interconnected assemblies. Some equipment may be located in the main control cabinet while other components are installed in remote cabinets or interface locations.
The NTRL03 can support this type of architecture by providing a dedicated remote-link terminal interface.
Its general system role may include:
- Remote system interconnection
- Signal interface organization
- Terminal connection
- Distributed control-system integration
- Cabinet wiring organization
- Maintenance support
- Remote equipment connectivity
A clearly structured remote link helps technicians understand the relationship between local and remote system equipment.
Importance of Reliable Remote Link Connections
Industrial control systems often operate continuously and may control critical process equipment. A fault in a remote connection can affect multiple signals or system functions.
Reliable terminal interfaces contribute to:
Signal Continuity
The terminal provides a defined interface for the associated remote connection.
System Availability
A secure connection helps reduce the risk of intermittent or disconnected system signals.
Maintenance Efficiency
Clearly identified terminal connections make troubleshooting and replacement more straightforward.
System Organization
Dedicated terminal hardware helps maintain a structured relationship between control-system equipment and remote installations.
Expansion and Modification
A properly organized interface can simplify future maintenance or system modifications when supported by the system architecture.
Physical Dimensions and Installation Planning
The listed dimensions of the ABB Bailey NTRL03 6637359K2 are 100 × 130 × 56 mm.
These dimensions should be considered when planning installation space inside a control cabinet or equipment enclosure.
Installation planning should account for more than the physical body of the terminal.
Engineers should consider:
- Mounting location
- Connector access
- Cable-entry direction
- Adjacent modules
- Cabinet clearance
- Maintenance access
- Cable routing
- Ventilation
- Label visibility
Adequate service space should be provided so technicians can inspect and replace the terminal without unnecessarily disturbing adjacent equipment.
Weight and Mechanical Installation
The listed weight of the NTRL03 is 0.413 kg.
Although the terminal itself is relatively lightweight, connected cables and associated equipment can place additional mechanical loads on the installation.
The mounting arrangement should therefore provide stable support.
Important considerations include:
- Secure mounting
- Connector strain relief
- Cable support
- Cabinet vibration
- Mechanical shock
- Cable routing
- Accessibility
Cables should not be allowed to pull directly against terminal connections.
Industrial Automation Applications
Distributed Control Systems
The NTRL03 can form part of a distributed control architecture where system equipment is installed at multiple locations.
Process Automation
Process-control facilities often require remote connections between instrumentation, I/O assemblies, controllers, and interface equipment.
Power Generation
Power-generation facilities use extensive control and monitoring architectures containing multiple local and remote equipment sections.
Chemical Processing
Chemical plants may distribute control and I/O equipment throughout the facility. Remote link interfaces help organize system-level connections.
Water and Wastewater Treatment
Water-treatment facilities commonly use distributed instrumentation and control cabinets for pumps, valves, treatment equipment, and process measurement.
Manufacturing Automation
Manufacturing plants can use remote interfaces to connect control equipment located in different production areas or equipment cabinets.
Integration with Industrial Control Architecture
The NTRL03 can be viewed as part of the interconnection layer of an ABB Bailey automation system.
A generalized architecture may be:
Process Equipment
↓
Field Devices
↓
I/O and Control Equipment
↓
Local Interface
↓
NTRL03 Remote Link Terminal
↓
Remote System Section
↓
Controller / Supervisory System
The actual architecture can vary considerably depending on the host ABB Bailey platform and system design.
For this reason, the terminal should always be evaluated as part of the complete system rather than as an isolated component.
Installation Guidelines
Verify the Model and Part Number
Before installation, confirm both:
Model: NTRL03
Part Number: 6637359K2
Both identifiers are useful when confirming a replacement.
Inspect the Terminal
Check the component for:
- Cracks
- Physical deformation
- Damaged mounting points
- Corrosion
- Contamination
- Damaged connectors
- Loose mechanical components
Confirm Connection Locations
Before removing an existing unit, document the connection arrangement.
Photographs, labels, wiring records, and terminal references can help prevent incorrect reconnection.
Install Securely
The terminal should be mounted securely according to the applicable equipment installation arrangement.

Cable routing should prevent excessive tension or bending at the terminal connections.
Cable Management and Remote Link Wiring
Remote link installations may involve multiple cables entering or leaving a control cabinet.
Good cable management should provide:
- Clear identification
- Adequate strain relief
- Organized routing
- Easy service access
- Separation from high-power wiring where appropriate
- Protection against mechanical damage
Avoid routing cables where cabinet doors, cooling fans, sharp edges, or moving equipment could damage them.
Cables should also be supported so that their weight does not place excessive force on the NTRL03 terminal connections.
EMC and Signal Integrity Considerations
Industrial environments can contain substantial electromagnetic interference from motors, drives, contactors, switching equipment, and power supplies.
Remote link wiring should therefore follow the EMC practices applicable to the complete ABB Bailey system.
