Selection Guide
Use the following criteria to select the correct power supply module for your YOKOGAWA DCS system:
- Step 1 – Identify your DCS platform: CENTUM VP, CS 3000, or CS 1000
- Step 2 – Calculate total power load: Sum the power consumption of all I/O modules and field devices in the cabinet
- Step 3 – Select output rating: Choose PW102 for standard load; PW481/PW482 for high-load or redundant configurations
- Step 4 – Verify input voltage: Confirm site AC supply voltage (100–240 V AC universal or dedicated 110/220 V)
- Step 5 – Check redundancy requirement: For SIL or high-availability systems, pair with a redundant PSU module
- Step 6 – Confirm part revision: Provide existing module revision code to Konmask.com for exact-match sourcing

Replacement & Compatibility FAQ
Q: Can the PW102 be used as a direct replacement for the PW101?
A: The PW101 and PW102 share similar form factors but may differ in output current rating. Verify the power budget of your cabinet before substitution.
Q: Is the PW102 compatible with CENTUM VP R6?
A: Compatibility depends on the hardware revision of the PW102. Contact Konmask.com with your system version for confirmation.
Q: Can I use a third-party 24 V DC PSU instead of the PW102?
A: Technically possible if voltage, current, and connector specifications match, but this may void YOKOGAWA system warranty. Consult your system integrator.
Q: What is the lead time for the YOKOGAWA PW102?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 2–6 weeks depending on sourcing channel.
Q: Do you provide a warranty on the PW102?
A: Yes. Konmask.com provides a 90-day functional warranty on all power supply modules unless otherwise stated.
