YOKOGAWA PW481, PW482, PW484 series power modules

Basic Information

Positioning: This document is the General Specification Manual (GS 33J60E70-01EN) for Yokogawa Electric's PW481, PW482, and PW484 series power modules. It was released in January 2021 and is the first edition. Its core purpose is to provide technical guidance such as module hardware parameters, installation specifications, and ordering information.

Product positioning: This series of modules is an exclusive power module and cannot be used as a universal power supply. It is only compatible with the control units and relay units specified by Yokogawa.

Details of Core Technical Parameters

The core parameter differences of the three modules are concentrated in the input power specifications, while the other key physical and interface parameters are consistent, as shown in the table below:

Parameter item PW481 PW482 PW484

Input power supply voltage 100~120 V AC ± 10% 220~240 V AC ± 10% 24 V DC ± 10%

Input power frequency 50/60 Hz ± 3 Hz 50/60 Hz ± 3 Hz None (DC input)

Maximum power consumption 200 VA 230 VA 5.5 A

Weight approximately 1 kg, approximately 1 kg, approximately 1 kg

Input/output interface exclusive connector exclusive connector exclusive connector

Output parameter description without clear labeling (exclusive adaptation, dependent on target device) without clear labeling (exclusive adaptation, dependent on target device) without clear labeling (exclusive adaptation, dependent on target device)

Core features: AC input, non universal power AC input, non universal power DC input, non universal power supply

Installation specifications and compatible equipment

Adaptation installation unit

FCU (Field Control Unit): AFV30D, AFV30S, A2FV50D, A2FV50S, A2FV70D, A2FV70S

FIO Node Unit: ANB10D, ANB10S, ANB11D, ANB11S

Optical ESB Bus Repeater Unit: ANT10U

Installation restrictions (key requirements)

Slot requirements: must be installed in slots P1-P2;

Single module configuration: can only be installed in slot P1;

Dual redundancy configuration: Two identical modules (including suffix codes) need to be installed.

Model coding rules (suffix code description)

The suffix code rules for the three modules are completely consistent, used to distinguish between explosion-proof levels and special function options, as shown in the following table:

The suffix code function description applies to all models

-5 standard type, without explosion-proof protection

-E standard type, with explosion-proof protection

0 basic type (without additional functional options) is

1 with ISA Standard G3 option, suitable for temperature range -20 ℃~70 ℃

Ordering and Applicable Standards

Ordering requirements: When ordering, it is necessary to clearly specify the "module model+suffix code", for example, "PW481-E-1" represents a power module with 100-120V AC input, explosion-proof protection, support for ISA G3 standard and wide temperature range.

Explosion proof selection: If it needs to be used in explosion-proof scenarios, it is necessary to refer to the related document "TI 33Q01J30-01E" to confirm the compliance of the selection.

Applicable standards: The module as a whole follows the relevant standards in the Integrated Production Control System CENTUM VP System Overview (document number: GS 33J01A10-01EN).

External dimensions and tolerances

Core dimensions (unit: mm): 146.5 × 49.7 × 190 (key external dimensions), total length 199.5mm, substrate adaptation width 149mm;

Tolerance standard:

0.5mm~120mm size segment: tolerance ± 0.8mm, combination tolerance ± 1.5mm;

Exceeding 120mm size segment: Follow the JEM 1459 standard.
