Description Reviews

Yokogawa PW301 Power Supply Module

Configured for 100-120 VAC to DC voltage conversion and backplane power distribution in CENTUM CS/VP systems, the Yokogawa PW301/100, also cataloged as the PW301 Power Supply Module, provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

Base Model (PW301): Standard Yokogawa System Power Supply Module designed to supply regulated DC power to Field Control Units (FCUs) and system communication buses.
Voltage Suffix (/100): Designates the 100-120 VAC input line voltage configuration operating at 50/60 Hz with a 6.0 A maximum input current rating.

Galvanic Isolation & Fieldbus Loop Power Dynamics

The PW301/100 module features complete galvanic isolation between the primary AC input and secondary DC output channels to prevent external line noise from corrupting internal bus signals. By delivering separate, regulated 5.1 VDC and 24 VDC rails, the unit insulates internal logic components while providing continuous power for 4-20 mA HART loops and fieldbus communication interfaces connected across the Field Control Unit chassis.

Frequently Asked Questions

Q: Does the PW301/100 support hot-swapping during active system operations?

A: Yes, hot-swapping is supported when the chassis is configured in a dual-redundant power setup and the secondary PW301/100 module carries the full system load.

Q: What primary mounting methods are supported for the module frame?

A: The module installs directly into dedicated power supply slots within the standard CENTUM CS/VP rack chassis using guide rails and secure faceplate mounting screws.

Q: How does the unit protect downstream logic cards from power surges?

A: Integrated overvoltage and fused overcurrent protection circuits automatically trip and clamp output lines to restrict fault current propagation into sensitive backplane logic.

Field Installation Guidelines

Line Voltage Disconnection: De-energize primary 100-120 VAC power feeds before wiring input terminals unless replacing a faulty unit under a verified online dual-redundant setup.
Slot Alignment: Slide the module straight into the designated power supply slot along card cage guide channels until the rear multi-pin system connector seats fully against the backplane.
Screw Attachment: Torque the top and bottom retaining thumbscrews to secure the assembly against vibration and establish continuous frame grounding to the chassis frame.
Conductor Separation: Route AC line voltage power cables away from low-voltage DC signals and fieldbus cables to prevent electromagnetic noise induction into analog control loops.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
