Yokogawa SB Bus T-joint NFSBT01 NFSBT02
Features
Yokogawa SB Bus T-joint NFSBT01 NFSBT02
• High-performance, high-reliability modular controller
• Memory with ECC
• Low heat dissipation eliminates the need for a fan
• A wealth of RAS features -CPU self-diagnostics, temperature monitoring, I/O diagnostics, and more
• The CPU, power supply module, local bus (SB bus), and control network can all be duplexed, and all modules are hot-swappable.
• Can function as link active schedulers (LASs) for low-speed voltage mode (H1) FOUNDATION Fieldbus segments, and link up FOUNDATION Fieldbus-enabled field devices.
Configuration
Yokogawa SB Bus T-joint NFSBT01 NFSBT02
An FCN-100 consists of the following:
• Base module
• Power supply module
• CPU module
• SB bus repeat module (extending the SB bus, the local bus for FCNs, to connect an extension unit)
• I/O modules
There are two types of base module.
- NFBU200 base module (long): Up to 2 extension units connectable for I/O expansion
- NFBU050 base module (short): Compact and dedicated to one-unit-configuration

SB Bus Repeat Module
Used to connect a control unit to I/O extension units. To duplex the SB bus, install two SB bus repeat modules in each unit.
Each SB bus repeat module is connected to another via a dedicated T-joint and cable.
