Yokogawa PW402 Power Supply Module
A Yokogawa CENTUM power supply module whose exact electrical execution is controlled by the installed label and host-system record.
Product Identification
Yokogawa PW402 is a CENTUM control-system power supply module. The exact host position and electrical execution must be taken from the installed assembly label and its system documentation.
Because power modules sit inside a larger supply and redundancy design, selection is made against the complete chassis, companion supply, input source and load record rather than the model string in isolation.
A concise service file should retain the label, rack location, connector arrangement and approved isolation/return-to-service procedure.
Engineering Data
Functions
System power role
Supports the documented power architecture of its assigned CENTUM hardware position.
Chassis integration
Operates as part of the host assembly rather than as an independent field power supply.
Service identity
Uses the exact module and rack record to control like-for-like maintenance.
About IndustryParts
https://www.industryparts.com/Exact-model handling for PW402
IndustryParts keeps the complete PW402 identity, requested quantity and installed-system evidence together so the proposed supply can be checked against the actual application before dispatch.
Applications
Installed-system spare
Maintains a documented PW402 position in an existing CENTUM control installation.
Planned maintenance
Supports controlled replacement where source, companion hardware and load state are already recorded.
Cabinet restoration
Returns the host power arrangement to its approved physical and electrical configuration.
Lifecycle
Document
Retain module and chassis labels, slot, source, companion supply and connector photographs.
Control
Use the site isolation and stored-energy procedure before releasing the power module.
Verify
Confirm host startup, supply health indications, redundancy behavior where configured and stable system operation.
FAQ
What information is required to quote PW402 accurately?
Provide the complete module and host-chassis labels, rack position, connector photographs, companion supply identity and requested quantity.
Can electrical ratings be selected from the PW402 name alone?
No. Use the installed label and Yokogawa host-system documentation to confirm source and system compatibility.
What should be recorded before removing PW402?
Capture system state, active supply path, alarms, rack position, cable/connector orientation and the approved isolation plan.
How should a redundant installation containing PW402 be serviced?
Follow the system procedure for the documented pair and prove the remaining path can carry the required load before disturbing either module.
What indicates a completed PW402 replacement?
Record secure installation, normal power indications, cleared alarms, expected redundancy state and stable controller operation after the approved observation period.
