Yokogawa Power Supply Module NFPW442-51 (220-240 V AC input)
Features
Yokogawa Power Supply Module NFPW442-51 (220-240 V AC input)
• 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 Power Supply Module NFPW442-51 (220-240 V AC input)
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

Power Supply Module
Mounted on a base module, a power supply module supplies steady power to other modules. Two power supply modules can be installed on a base module for redundancy.
This power supply module is equipped with input terminals for a 24 V DC power supply in addition to the main power input. The 24 V DC power input from these terminals are referred to as analog field power supply and fed to analog I/O modules to drive their field interface circuits and supply power to the connected field devices through the base module.
However, when a 24 V DC power supply is needed for digital outputs, it must be supplied to individual terminals of the corresponding I/O modules. (For details, see the respective specifications for I/O modules.)
