Overview Manuals Specifications Application Firmware & Updates Configuration & Programming

Features:

  • PW482-51 S2 provides 230VA 220-240V AC power with dedicated connector for Yokogawa CENTUM VP systems.
  • Dual-redundant configuration support with two identical modules ensures continuous operation for critical control applications.
  • ISA Standard G3 option delivers corrosion resistance and -20°C to 70°C operation for harsh industrial environments.
The PW482-51 S2 is specifically engineered as a dedicated power supply module for Yokogawa's CENTUM VP distributed control system components. Unlike generic power supplies that can be used across various equipment, the PW482-51 S2 is exclusively designed for Field Control Units (FCU models AFV30D, AFV50D, AFV70D), FIO Node Units (ANB10D, ANB11D), and Optical ESB Bus Repeater Units (ANT10U). This specialization ensures that the output voltage and current characteristics are precisely matched to the power requirements of these Yokogawa components, providing reliable and stable operation.

The PW482-51 S2 supports dual-redundant power configurations, a critical feature for continuous process control applications where power supply failure cannot be tolerated. By installing two identical PW482-51 S2 modules in slots P1 and P2 of the base plate, the system can tolerate a single power supply failure without interrupting operation. If the primary module fails, the secondary module automatically continues to supply power to the FCU, FIO Node, or ESB Repeater unit. In single configuration, the PW482-51 S2 must be installed in slot P1. For redundant operation, both modules must have identical model codes to ensure proper load sharing and failover characteristics.

The PW482-51 S2 with suffix code 1 includes the ISA Standard G3 option, providing enhanced protection against corrosive atmospheres. The G3 classification per ISA S71.04 indicates the module is designed for harsh environments where airborne contaminants such as sulfur dioxide, hydrogen sulfide, chlorine, and other corrosive gases may be present. This makes the PW482-51 S2 suitable for installation in chemical plants, refineries, wastewater treatment facilities, and offshore platforms where standard electronics would rapidly deteriorate. The G3 option also extends the operating temperature range to -20°C to 70°C, allowing the PW482-51 S2 to function in unheated control rooms, outdoor enclosures, and extreme climate locations.

The PW482-51 S2 YOKOGAWA Input Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Mission-Critical Power Generation: Main boiler controls, steam/gas turbine interlocks, and nuclear auxiliary balance of plant (BOP) machinery.
  • No Firmware Required: Because it contains no microcode or digital operating system, it has no firmware to manage or update. There is no software tool, utility, or flashing procedure associated with this unit.
  • The S2 Style Code: The trailing S2 represents a manufacturing Style Code (Style 2). This indicates second-generation layout adjustments completed at Yokogawa’s factories (such as upgraded thermal layout or longer-lived heavy capacitors). The Style 2 module remains completely plug-compatible and backward-compatible with legacy Style 1 units.
  • Dedicated Slotting: Within a Field Control Unit (FCU) or an FIO Node Unit rack, power supply slots are hard-coded on the extreme left. They are designated as slots P1 and P2.
  • Single Layout: If redundancy is not required by site design, a solitary PW482 must be positioned exclusively in the P1 slot.
  • Dual-Redundant Layout: For mission-critical tasks, matching PW482 modules are installed into both P1 and P2 slots. Internal load-sharing circuitry balances current distribution evenly (roughly 50/50) under standard conditions.
Description
The PW482-51 S2 is a 220-240V AC input power supply module designed for Yokogawa CENTUM VP Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units. The PW482-51 S2 features an exclusive input/output connector and is designed to be installed in slots P1-P2 of compatible base plates including AFV30D, AFV50D, AFV70D, ANB10D, ANB11D, and ANT10U.

The PW482-51 S2 supports dual-redundant power configurations by installing two identical modules in slots P1 and P2. In a single configuration, the module must be installed in slot P1. The PW482-51 S2 suffix codes indicate: -5 for standard type with no explosion protection, and 1 for ISA Standard G3 option with extended temperature range of -20°C to 70°C. 

The PW482-51 S2 is a dedicated power supply module for Yokogawa's distributed control system and cannot be used as a generic power supply. The PW482-51 S2 provides exclusive power output to FCU, FIO Node, and Optical ESB Bus Repeater units only. 

For explosion protection requirements, the PW482-51 S2 standard type (-5) has no explosion protection. Users requiring explosion protection should select the -E suffix version. The PW482-51 S2 dimensions follow Yokogawa's standard form factor for CENTUM VP series components.
