YOKOGAWA F3PU06-0N Core power module

The YOKOGAWA F3PU06-0N is a core power supply module for the FA-M3 (Free Application Multi-controller) series.

It is responsible for converting external power into the internal DC voltage required to run the CPU and I/O modules on the controller backplane.

1. Introduction

The F3PU06-0N is a standard AC-input power supply module. In the FA-M3 architecture, every base unit (rack) requires its own power supply module, typically installed in the leftmost slot.

The "06" in the model name indicates its power capacity class, specifically designed for small-to-medium configurations (typically paired with 4 to 6-slot base modules like the F3BU06-0N).

3. Product Advantages and Features

Compact Design: Occupies a single slim slot on the FA-M3 base, allowing more room for functional I/O modules.

Wide Input Range: Supports universal AC power (100–240V), making it compatible with global industrial power standards without needing external transformers.

High Noise Immunity: Specifically engineered to handle the electrical "noise" (spikes/surges) common in factory environments ($1500text{Vp-p}$ noise resistance).

Failure Detection: Features a "FAIL" output contact that can be wired to an external alarm or safety circuit to signal if the power supply has dropped or malfunctioned.

Hot-Swap Protection: While modules should generally be replaced with power off, its construction is highly robust against the mechanical stresses of industrial maintenance.

4. Application Cases

The F3PU06-0N is an essential component in any system using the FA-M3 PLC, commonly seen in:

Machine Tool Control: Providing stable logic power for high-speed CNC or machine-tending robots.

Semiconductor Fabrication: Used in small-scale wafer processing equipment where clean, reliable DC power is critical for sensor accuracy.

Utility Monitoring: Powering controllers that manage building HVAC or water treatment filtration systems.

Packaging Lines: Supporting the fast logic processing required for synchronized capping and labeling machines.

5. Other Models in the Same Series

Yokogawa offers several power supply variants depending on the size of the rack and the input power available:

F3PU10-0S: The current replacement/standard for AC power on small racks.

F3PU16-0N: DC-input version (24V DC) for mobile or battery-backed systems.

F3PU20-0S: Higher capacity (4.3A output) for 9-to-16-slot base modules.

F3PU30-0S: Ultra-high capacity (6.0A output) for racks heavily populated with power-hungry analog or communication modules.

F3PU36-0S: High-capacity 24V DC input module.

Maintenance Note: This model is part of Yokogawa's "End-of-Sale" transition.

 While many units are still in service, the F3PU10-0S is the recommended modern successor if you are designing a new system or performing a full controller upgrade.
