NDSM03 ABB Bailey Termination Unit

Product  Description：

• • An ABB Bailey Termination Unit is a crucial component within ABB's process control systems, such as the INFI 90 and Symphony Plus series. Its primary role is to act as an interface between the control system's I/O modules and the field devices (sensors, transmitters, and actuators). Essentially, it provides a secure and organized way to connect field wiring to the sensitive electronics of the control system.

     

    Key Functions

     

    • Wiring Termination: The unit provides screw terminals or other connectors for field wiring, making it easy to connect and disconnect field devices without disturbing the I/O module.

    • Signal Conditioning and Isolation: Some termination units provide signal conditioning, filtering, and isolation to protect the control system from electrical noise, surges, and ground loops from the field wiring.

    • Mechanical and Electrical Support: It provides the physical mounting and electrical termination for I/O modules, which are typically inserted into the termination unit.

    • Simplifying Maintenance: By separating the field wiring from the I/O module, a termination unit allows for hot-swapping or replacement of a module without rewiring the field devices, minimizing downtime and simplifying maintenance.

     

    Product Parameters (Typical)

     

    Parameters vary significantly depending on the specific model and function (e.g., analog input vs. digital output). Here are some typical examples:

    • System Compatibility: Designed for specific ABB Bailey DCS platforms (e.g., INFI 90, Symphony Plus).

    • Module Type: Analog Input (e.g., NTAI06), Analog Output, Digital Input, Digital Output, Communication.

    • Input/Output Channels: The number of field signals it can handle (e.g., 8, 16, or more channels per unit).

    • Field Wiring Connection: Screw-type terminals, spring-cage terminals, or other types of connectors.

    • Signal Types (for I/O):

      • Analog Input: 4-20 mA, 1-5 VDC, thermocouples, RTDs.

      • Digital Input: 24 VDC, 48 VDC, 120 VAC.

    • Power Requirements: Usually powered by the rack or external 24 VDC supply.

    • Mounting: DIN rail or panel mount.

    • Environmental Ratings: Operating temperature range (e.g., -40°C to +70°C), humidity (e.g., 5% to 95% non-condensing).

     

    Product Advantages

     

    • Robust and Reliable: Built for the demanding conditions of industrial environments, ensuring system uptime and longevity.

    • Enhanced Safety: Provides a secure point for wiring and offers electrical isolation, protecting the control system's electronics from potentially damaging field conditions.

    • Simplified Maintenance and Troubleshooting: Facilitates easy and quick replacement of I/O modules, which significantly reduces maintenance time and effort. Technicians can work on the field wiring without disturbing the control module.

    • Organized and Tidy Wiring: Creates a clean and organized wiring scheme, which is essential for clear documentation, quick troubleshooting, and safety.

    • Modularity and Scalability: The modular design allows for easy system expansion or modification by simply adding or replacing termination units and their associated modules.

     

    Precautions

     

    • Compatibility: Always verify that the termination unit is compatible with the specific I/O module and the overall ABB Bailey system it will be used with. Using an incompatible unit can cause system malfunctions.

    • Wiring Standards: Strictly follow all wiring diagrams and local electrical codes. Incorrect wiring can lead to short circuits, system damage, or safety hazards.

    • Power Down: It's highly recommended to turn off the power to the cabinet before performing any wiring to prevent electrical shock or equipment damage.

    • ESD Protection: Always use proper electrostatic discharge (ESD) procedures when handling the unit to protect the sensitive electronic components.

     

    Product Applications

     

    ABB Bailey Termination Units are a foundational element in industrial process control and automation. They are used in any application that employs an ABB Bailey DCS.

    • Power Generation: Controlling boilers, turbines, and generators.

    • Oil and Gas: Managing processes in refineries, pipelines, and offshore platforms.

    • Pulp and Paper: Automation of paper machines and chemical recovery systems.
