Yokogawa SPW482-11 Power Supply Module

The Yokogawa SPW482-11, also cataloged as the PW482-11 Power Supply Module, operates as a dedicated hardware component for 100-240 VAC to DC voltage conversion and regulated power distribution within CENTUM VP and ProSafe-RS control chassis networks.

Suffix Breakdown & Model Matrix

Base Model (SPW482 / PW482): Yokogawa System Power Supply Module designed to supply Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units.
Voltage Suffix (-11): Identifies the specific wide-range AC input specification variant operating at nominal 100-240 VAC (rated 220-240 VAC +/-10%, 50/60 Hz).
Replacement Notice: Legacy hardware designation (replaced by SPW482-53 in updated lifecycle iterations).

Galvanic Isolation & Fieldbus Loop Power Dynamics

The SPW482-11 incorporates galvanic isolation between the primary AC line input and secondary DC supply outputs to prevent common-mode voltage spikes from impacting sensitive internal system buses. By providing dual-rail power outputs (5.1 VDC for internal logic logic solver cards and 24 VDC for field instrumentation loops), the module maintains isolation integrity for connected 4-20 mA HART loops and fieldbus communication interfaces across the FCU node architecture.

Frequently Asked Questions

Q: Which dedicated chassis slots accept the SPW482-11 power supply module?

A: Mount the SPW482-11 exclusively into designated power supply slots P1 or P2 within Yokogawa FCU or FIO node chassis frames to interface with the proprietary system backplane connector.

Q: How does the SPW482-11 maintain system operation during power module replacement?

A: When installed in a dual-redundant configuration (occupying both P1 and P2 slots), one active SPW482-11 module supports the complete DC load, allowing live replacement of a faulty adjacent unit without interrupting system operations.

Q: What cooling considerations apply during physical installation?

A: Secure the module with adequate vertical clearance above and below the card cage to maintain natural convection airflow and prevent thermal derating of internal power conversion components.

Field Installation Guidelines

Power Disconnection: Isolate external main AC feeder circuit breakers prior to connecting input power wiring to the chassis terminal block, except when performing a hot-swap operation in a confirmed dual-redundant power setup.
Slot Alignment: Slide the module horizontally or vertically along chassis card guides into slot P1 or P2 until the rear proprietary system connector engages completely with the backplane.
Fastener Engagement: Tighten the top and bottom retaining thumbscrews manually or with a standard screwdriver to ensure solid chassis grounding and structural lock under industrial vibration.
Line Cable Routing: Route AC input lines through dedicated wire channels away from low-voltage DC signals and optical ESB bus cables to minimize electromagnetic coupling.
