FAQ
Q1: What is the Yokogawa PW402 used for?
It is a power supply module for Yokogawa CENTUM VP / CS 3000 DCS systems, providing regulated DC power to the CPU, communication bus, and I/O modules within the Field Control Station .
Q2: What are the exact output specifications?
This is the most critical point of confusion. The most frequently cited specification for the CENTUM PW402 is +5.1V DC at 20A (102W) . However, other sources claim 24V DC output or dual 5V/24V outputs . You must obtain the official Yokogawa datasheet for the exact order number (including any suffix) to confirm the output voltage and current.
Q3: Does the PW402 support redundancy?
Yes, it is designed to be installed in pairs for dual-redundant configuration, ensuring continuous operation if one module fails .
Q4: What is the input voltage?
Sources cite 100–120 VAC or 200–240 VAC (selectable), or a wide range of 100–240 VAC .
Q5: What is the difference between PW402 and PW401?
One source describes the PW402 as a "next-generation redundant power supply" with enhanced precision (±0.3V vs. ±0.5V) and higher surge immunity compared to the PW401 . However, this source's specifications (24V, 20A, 4kV surge) conflict with other sources describing the PW402 as a 5.1V CENTUM power supply. Verify the exact model relationship with Yokogawa.
Q6: What is the difference between PW402 and PW402 S2?
The S2 suffix indicates a style revision. One source describes the PW402 S2 as a +5.1V, 20A, 102W module . Confirm the exact compatibility of the S2 variant with your system revision.
Q7: Is this a current or legacy product?
The PW402 is associated with CENTUM VP / CS 3000 systems, which are mature platforms. Confirm current product status and availability with Yokogawa or an authorized distributor.
Q8: Where can I get technical documentation?
Official Yokogawa documentation is essential. The third-party search results are unreliable and contradictory. Contact Yokogawa or an authorized distributor directly for the datasheet matching your exact order number.
