Description
The Yokogawa F3PU10-0N is an AC input power supply module designed for the Yokogawa FA-M3 (Free and Multi-Abled) and FA-M3V programmable logic controller series. It mounts directly into the dedicated power slot of an FA-M3 base unit, converting line-voltage AC power into a regulated 5 V DC logic rail to drive the CPU, backplane communications, and attached I/O modules.

Engineering Context and Field Integration
When installing the F3PU10-0N within Yokogawa FA-M3 controller racks, system integrators must account for physical layout constraints and electrical protection requirements:
- Slot Allocation: This module is strictly designed for the leftmost dedicated power slot of compatible FA-M3 base units (such as the F3BU06-0N). It cannot be placed into standard I/O slots.
- Diagnostics & FAIL Output: The front panel features a status LED indicating a normal “Power OK” state. The unit also incorporates a hardware FAIL output contact that opens if the regulated 5 V DC rail drops below operational thresholds, providing a discrete signal for external emergency shutdown loops.
- Thermal Management: Maintain a minimum clearance of 50 mm above and below the base rack assembly. Natural convection cooling relies on unobstructed airflow across the module’s enclosure heatsink vents.
Frequently Asked Questions
Can the F3PU10-0N be hot-swapped during active system operation?
No. Hot-swapping the F3PU10-0N is strictly prohibited. Disconnecting or inserting the power supply module while AC mains voltage is applied will cause an ungraceful system crash, instantly dropping the backplane 5 V DC bus and halting CPU execution. Always isolate upstream power before servicing.
How does the module handle short circuits on the backplane?
The unit features built-in overcurrent and short-circuit protection. If a fault pulls down the 5 V DC rail, the internal protection circuit trips to prevent component damage. Once the external fault is cleared, the power supply recovers automatically without requiring physical fuse replacements.
Is this module compatible with DC-powered control panels?
No. The F3PU10-0N requires an AC input source (100 to 240 V AC). For 24 V DC-powered
