Product Description
The NFPW444 is a high-reliability DC power supply module for Yokogawa STARDOM FCN-RTU and FCN-500 controllers. It converts 24 V DC input into a precise 5.1 V DC logic output for the system backplane. A secondary 24 V DC output is provided for analog field interface circuits and connected field devices. The module supports hot-swappable dual-redundant configurations, ensuring the controller remains operational even during maintenance or module replacement.
