製品紹介
The Yokogawa SPW482 is a high-reliability power supply module designed to provide regulated power for Field Control Stations (FCS) in Yokogawa’s CENTUM VP and CENTUM CS 3000 distributed control systems. As part / Yokogawa’s modular DCS architecture, the SPW482 plays a critical role in supplying stable DC voltage to processor modules and I/O cards housed in a system cabinet.
Built for redundancy, the SPW482 can operate in standalone or parallel-redundant mode, ensuring uninterrupted power even in the event / a module failure. Its intelligent load-sharing design helps balance power output when used with a second SPW482 in redundant configurations, minimizing system downtime and maintenance.
This module is known for its long operating life, robust performance under harsh industrial conditions, and intelligent diagnostics, making it a core power infrastructure component in mission-critical automation systems across industries.

よくある質問 (FAQ)
-
What is the primary function / the SPW482 module?
It supplies 24V DC power to Yokogawa control systems, including processors and I/O modules. -
Can the SPW482 be used in a redundant configuration?
Yes, two SPW482 modules can be paired for redundancy, ensuring continuous power even if one fails. -
Is the module hot-swappable?
No, the SPW482 should be powered down before replacement unless installed in a redundant setup. -
What happens if the power supply fails during operation?
In a redundant configuration, the second SPW482 takes over automatically without system disruption. -
Does it provide any overload protection?
Yes, it features over-current, over-voltage, short-circuit, and thermal protection mechanisms. -
Can the SPW482 handle varying AC input voltages?
Absolutely. It auto-switches between 100–120V and 200–240V AC input ranges. -
How do I know if the module is functioning properly?
LED indicators on the module show status, alarms, and communication activity in real time. -
