Description
Product Overview
Part Number: PW482-10 Manufacturer: Yokogawa (Yokogawa Electric, Japan) Product Series: CENTUM VP DCS, FCU / FIO Node Power Supply Module Type: AC Input DCS Power Supply Module PW482-10 is a 220~240VAC input power supply module for Yokogawa CENTUM VP. It can be installed in AFV Field Control Unit (FCU) or ANB10/ANB11 FIO node cabinet. It converts AC mains into stable regulated internal power for CPU, ESB bus coupler, backplane and all FIO I/O modules. The -10 suffix indicates it adopts ISA G3 environmental specification, suitable for industrial sites with vibration, dust and corrosive gas. Two PW482-10 modules can be configured for dual-redundant power to eliminate single-point power failure. Widely applied in petrochemical, power, oil & gas and chemical process plants. Supports hot-swap replacement while DCS online.

Engineer Notes
- PW482-10 is 220~240VAC input version, equipped with ISA G3 environmental option. Compare with PW482-50 which is standard general-purpose version without G3.
- Dual redundant configuration: install two PW482-10 in same FCU or FIO node. Automatic seamless switchover when one power module fails, no impact on control and I/O acquisition.
- Supports hot swap. Faulty PW482-10 can be pulled out and replaced while the DCS node remains online.
- Front panel LED indicators show power status, fault alarm and redundancy health for quick on-site diagnosis during commissioning and routine maintenance.
- G3 environmental rating makes it fit for harsh industrial cabinet environments with vibration, airborne contaminants and condensation risk.
- Recommended service life for PW482 series power modules is 8 years; periodic preventive replacement is required for long-term plant operation.
- Only used for CENTUM VP FIO/N-IO system; not compatible with legacy CS3000 DCS hardware.
Pre-Shipment Test Protocol
- Power-on test and power status LED verification
- Full load output stability test
- Redundancy switchover simulation test
- Overload and short-circuit protection functional test
- Internal circuit continuity & insulation inspection
- Visual inspection of housing, connectors, label and marking
- Anti-static & shockproof packaging inspection
Buyer FAQ
Q: Is PW482-10 new original? A: We supply brand new original Yokogawa units, 12-month warranty, factory test certificate available on request.
Q: What does suffix -10 mean? A: The first digit “1” = ISA G3 harsh environment option; “0” = basic non-ex-proof version. PW482-10 supports higher vibration and contaminant resistance than PW482-50.
Q: What is the difference between PW482-10 and PW482-50? A: PW482-10: 220-240VAC, ISA G3 environmental grade for harsh cabinet conditions. PW482-50: standard general indoor version without G3 option. Same electrical power rating.
Q: Does PW482-10 support redundant power supply? A: Yes. Two PW482-10 modules can be installed in the same FCU or FIO node to realize dual redundant power supply.
