Product Overview
The Yokogawa NFSBT02 is an SB Bus T-Connector with Built-In Terminator designed for Yokogawa distributed control systems (DCS). It is used to connect SB Bus communication cables while providing integrated bus termination to maintain signal integrity and ensure reliable communication across the automation network.
The NFSBT02 simplifies SB Bus wiring by combining a T-connector and termination resistor into a single compact unit. It is particularly suitable for system expansion, branch connections, and end-of-line bus termination in Yokogawa control architectures.

Function and Working Principle
The NFSBT02 connects SB Bus communication cables while incorporating a built-in termination resistor that minimizes signal reflections and maintains communication quality.
Installed at the appropriate point in the bus topology, it ensures that communication signals are properly terminated, contributing to stable and reliable data transmission throughout the automation network.
Operating Sequence
- SB Bus communication cables are connected through the T-connector.
- Communication signals pass through the connector to connected devices.
- The integrated terminator absorbs reflected signals at the end of the bus.
- Signal integrity is maintained across the communication network.
- Stable communication is ensured between controllers and remote modules.

Frequently Asked Questions
What is the NFSBT02 used for?
It is used as an SB Bus T-connector with an integrated terminator, providing both bus connection and end-of-line signal termination in Yokogawa communication networks.
Why is bus termination important?
Proper termination reduces signal reflections and helps maintain reliable communication across the SB Bus network.
Does the NFSBT02 process communication data?
No. It is a passive communication accessory that provides physical bus connection and termination rather than processing data.
Where is it installed?
It is installed at designated connection or termination points within the Yokogawa SB Bus network.
Which systems commonly use the NFSBT02?
It is used in Yokogawa distributed control systems across industries such as oil and gas, power generation, chemical processing, water treatment, manufacturing, and other industrial automation applications.
