YOKOGAWA PW501 Power module
The Yokogawa PW501 is a specialized Power Supply Module typically integrated into the FA-M3 (Factory Automation Micro-3) range of programmable logic controllers (PLCs).
Known for its “Range-free” multi-voltage capabilities, it serves as the literal powerhouse for the CPU and I/O modules within the rack.
1. Introduction
The PW501 is designed to provide stable DC power to the internal logic of the FA-M3 system.
Its standout feature is its ability to handle a wide range of input voltages (AC 100-240V) without manual switching, making it a “world-ready” component for global manufacturing lines.
It also includes built-in protection and status signaling to ensure system integrity.
