PW482-E0 S2

The Yokogawa PW482-E0 S2 is an AC input power supply module designed for Yokogawa control system hardware. The PW482 model is specified for a 220-240 V AC input supply and uses a dedicated module interface rather than serving as a general-purpose power supply. Its application and installation depend on the compatible control unit or node configuration.

Power Supply Function and System Integration

The PW482 supplies power to the internal circuitry of compatible Yokogawa equipment. It is intended for installation in a Field Control Unit (FCU), FIO Node Unit or Optical ESB Bus Repeater Unit. Its dedicated connector provides the electrical interface to the host unit.

The module is not intended for use as a standalone DC power supply. Yokogawa does not specify generic output voltage and current ratings for the PW48 series because its power distribution function is designed specifically for the associated system hardware.

Ordering Code Identification

The supplied model designation contains the following identifiable ordering information:

• PW482: 220-240 V AC input power supply module.
• -E: Standard type with explosion protection.
• 0: Basic type.
• S2: Retained as part of the supplied model designation.

The -E and 0 suffix descriptions follow Yokogawa's published ordering information. Explosion protection selection should be checked against the applicable installation requirements and Yokogawa document TI 33Q01J30-01E.

Installation and Redundancy

Yokogawa specifies the PW48 series for the following equipment:

• FCU: AFV30D, AFV30S, A2FV50D, A2FV50S, A2FV70D and A2FV70S.
• FIO Node Unit: ANB10D, ANB10S, ANB11D and ANB11S.
• Optical ESB Bus Repeater Unit: ANT10U.
• Base Plate: A2BE1D and A2BE2D.

The module occupies slots P1 or P2. A single-module configuration uses slot P1. Dual-redundant power supply requires two identical modules with the same model code.

Frequently Asked Questions

Q: What input voltage does the PW482-E0 S2 require?

A: It requires a 220-240 V AC input supply at 50/60 Hz. It should not be confused with the PW481 (100-120 V AC) or PW484 (24 V DC).

Q: Can the PW482-E0 S2 operate as a standalone DC power supply?

A: No. It is a dedicated power supply module for compatible Yokogawa control units and node equipment. Its output specifications are not defined for general-purpose power supply applications.

Q: Can two PW482 modules be used for power redundancy?

A: Yes. Yokogawa supports dual-redundant configurations using two identical modules with the same model code, installed in the designated P1 and P2 slots.
