Yokogawa Power Supply Module NFPW444-E1
Features
• 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
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
