Fuji NP1PS-32R CPU Module | MICREX-SX Redundant Power

Integrated Processing with Redundant Power Inputs

This combined unit provides system power and central processing in one module. The Fuji NP1PS-32R supplies stable DC power to all backplane cards. It executes user programs for medium-sized automation tasks efficiently. Dual power input terminals allow connection to two separate 24V DC sources. Consequently, this module ensures continuous operation even if one power supply fails.

Power Output & Redundancy Features

The Fuji NP1PS-32R delivers reliable power for up to 10 I/O modules in your rack. You can connect two external power supplies for true redundancy. The unit automatically switches between sources without any processing interruption. A status LED indicates which power supply is currently active. Therefore, this CPU suits critical applications where downtime costs exceed hardware expenses.

Installation & Redundant Configuration

You insert the Fuji NP1PS-32R 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-32R 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. A PS ACTIVE LED shows which power supply is currently feeding the system. Therefore, maintenance teams identify failed supplies before they cause system shutdowns.
