SYSTEM INTEGRATION
Match PW401 S2 to the installed CENTUM XL power modules
Yokogawa PW401 S2 is a power supply module for the CENTUM XL power modules. Its exact article suffix determines the supported interface, signal or communication function and the approved companion equipment.
Engineering should compare typical input power (400 VA), output voltage (5.1 V DC) and maximum output current (20 A) with the installed system design. Confirm connector keying, addressing and configuration-tool support before connection.
Use the manufacturer documentation for the complete wiring and configuration sequence. Validate communication, signal conversion or control response with the connected equipment, then archive measured results and the final configuration with the asset record.
Features:
- Exact identity: PW401 S2
- Product class: power supply module
- Family: CENTUM XL power modules
The Yokogawa PW401 S2 requires documented system integration before energising the equipment.
REPLACEMENT CONTROL
Verify the complete PW401 S2 identity before exchange
Replace PW401 S2 only after matching the complete article code, power supply module, installed CENTUM XL power modules role and documented hardware or firmware revision. Similar housings and related family numbers do not establish functional interchangeability.
Photograph the nameplate, keyed connectors, terminal numbering, cable routing, shields, earth points and adjacent modules. Export the applicable controller, HMI, drive or network configuration and record addresses, parameters and diagnostic messages before removal.
After fitting the verified article, restore the controlled configuration and check every affected signal or communication path. Review status indications and diagnostic buffers, run the documented functional test at a safe operating point and retain the final acceptance record.
Features:
- Exact identity: PW401 S2
- Product class: power supply module
- Family check: CENTUM XL power modules
The Yokogawa PW401 S2 requires documented replacement verification before energising the equipment.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about PW401 S2
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What makes PW401 S2 fit the commissioning retrofit task?
For PW401 S2 during retrofit planning, a commissioning engineer should match input voltage (100 to 120 V AC) and input frequency (50 or 60 Hz) to the installed CENTUM XL power modules design. A mismatch can prevent correct integration even when the hardware appears similar. -
Receiving PW401 S2 for commissioning retrofit: check 50 or 60 Hz input frequency?
For retrofit planning, identify PW401 S2 by the combined specification: input frequency is 50 or 60 Hz, while maximum input current is 4 A. A commissioning engineer should confirm both values rather than relying on the family name or enclosure. -
Commissioning retrofit: does PW401 S2 match 4 A?
Before wiring or mounting PW401 S2, a commissioning engineer should verify the installation supports maximum input current of 4 A and preserves the documented typical input power of 400 VA. Record this check in the retrofit planning work pack. -
Confirming PW401 S2 typical input power during commissioning retrofit?
During retrofit planning, a commissioning engineer should commission PW401 S2 under a controlled load or signal and confirm typical input power reaches 400 VA. Cross-check output voltage against 5.1 V DC, then save the measured result for engineering acceptance. -
PW401 S2 output voltage: 5.1 V DC or another value — commissioning retrofit?
During retrofit planning, a commissioning engineer should isolate the circuit, compare the actual output voltage with the PW401 S2 specification of 5.1 V DC, and inspect the related maximum output current requirement (20 A). This separates a module fault from a supply, wiring, or configuration issue. -
PW401 S2 selection check for commissioning retrofit: maximum output current?
For retrofit planning, the PW401 S2 service record should state maximum output current as 20 A and retain maximum output power at 102 W. These values give a commissioning engineer a repeatable baseline for later replacement and fault diagnosis. -
Distributor commissioning retrofit evidence for PW401 S2: maximum output power?
For a commissioning engineer's retrofit planning request, the quotation should identify the complete PW401 S2 code and confirm maximum output power (102 W) together with operating temperature (0 to 50 °C). The distributor should flag any revision or substitute that changes either requirement. -
PW401 S2 operating temperature for MRO commissioning retrofit?
For a commissioning engineer's retrofit planning requirement, check the delivered PW401 S2 label and order code, then verify operating temperature is 0 to 50 °C and input voltage is 100 to 120 V AC. Photograph the label and connectors before acceptance so purchasing and maintenance share the same identity record.
