Yokogawa SPW482-13 Power Supply Module
The Yokogawa SPW482-13 serves as the primary SPW482 Power Supply Module utilized to execute AC mains rectification and exclusive backplane power distribution across Yokogawa Field Control Unit (FCU) and FIO Node platforms.
Hardware Specifications
| Parameter | Specification |
|---|---|
| Model | SPW482-13 |
| Brand | Yokogawa |

Backplane Channel-to-Channel Isolation
Integrating within the Field Control Unit (FCU) and FIO nodes, the power module provides the fundamental voltage source required to drive standard 4-20 mA HART loop protocol interfaces across remote I/O bases. Its internal transformer components maintain strict channel-to-channel isolation on the backplane, ensuring that common-mode transients on the 220-240 VAC mains do not propagate to sensitive FOUNDATION Fieldbus or Profibus PA field instrumentation networks.
Frequently Asked Questions
Q: Can the Yokogawa SPW482-13 be deployed as a standalone or generic power supply?
A: No. The SPW482-13 utilizes an exclusive connector design and is engineered strictly to supply regulated voltage to designated Yokogawa architecture components, including the FCU, FIO Node Unit, and Optical ESB Bus Repeater.
Q: How is fail-safe hardware redundancy achieved with this power module?
A: The module supports dual-redundant load-sharing configurations. Installing two SPW482-13 units in parallel within the same FCU or FIO Node chassis ensures continuous backplane power delivery during a single-module failure.
Field Installation Guidelines
- Verify the incoming 220-240 VAC mains feed is completely de-energized and locked out before seating the module in the FCU or FIO Node Unit.
- Slide the module along the chassis guide rails until the exclusive backplane connector engages fully, avoiding excessive horizontal force.
- Tighten the front panel retaining screws to standard torque specifications to ensure grounding continuity and prevent vibration-induced disconnects.
- In dual-redundant power setups, ensure both SPW482-13 modules are fed from separate electrical distribution branch circuits to maximize availability.
- Ground the chassis backplane strictly to the main instrumentation earth bar to prevent AC leakage from affecting low-voltage I/O signals.
