Fuji NP1PS-117R CPU Module | Redundant Power Supply

Integrated Power Supply with Redundancy Support

This combined unit provides system power and central processing for critical automation tasks. The Fuji NP1PS-117R supports redundant power configurations for maximum system uptime. It supplies stable DC power to all backplane modules while executing user programs. A built‑in battery preserves program memory during unexpected power outages. Consequently, this module suits applications where downtime costs exceed hardware expenses.

Power Output & Redundancy Features

The Fuji NP1PS-117R delivers reliable power even when one supply source fails. You can connect two external power supplies to this module for true redundancy. The unit automatically switches between sources without any interruption to processing. It also tolerates wide voltage fluctuations common in industrial power grids. Therefore, this CPU maintains control during brownouts and voltage sags.

Installation & Redundant Configuration

You insert the Fuji NP1PS-117R into the dedicated power supply slot of your MICREX-SX rack. Connect two independent 24V DC power supplies to the redundant input terminals. The module then distributes clean DC power to all backplane cards automatically. You add your I/O modules in adjacent slots without additional power wiring. Consequently, a single power supply failure will not stop your production line.

Operational Advantages & Critical Applications

The Fuji NP1PS-117R combines power distribution with processing in one compact module. This integrated design saves rack space while adding redundancy capabilities. The lithium battery retains your program during power interruptions for up to 5 years. Dual LED indicators show the status of each connected power supply. Therefore, maintenance teams identify failed supplies before they cause system shutdowns.
