Key Technical Specifications

Technical note: Yokogawa specifies the PW482 for designated system assemblies and does not define it as a generic power supply with universal standalone output ratings. The host unit, exact suffix code, and installation documentation must be checked before selecting a replacement.

Product Introduction (Anti-Template)

When a distributed control system loses its power module, the consequences can extend beyond the supply component itself to the controller, I/O network, or field equipment it supports. The Yokogawa PW482-50 S2 is a dedicated AC input power supply module designed for compatible Yokogawa control-system assemblies. It accepts a nominal 220–240 V AC input and is used in designated field control units, FIO node units, and optical ESB bus repeater units.

The PW482 can form part of a dual-redundant power arrangement when two identical compatible modules are installed in the designated positions. It should not be selected solely by matching the input voltage: confirm the host unit, slot arrangement, complete model code, and suffix requirements. Honestly, verifying the host assembly first is more reliable than trying to match an assumed standalone DC output rating.

QC, Procurement & Logistics SOP

1. Inbound Verification
   Inspect the Yokogawa nameplate and verify PW482-50 S2. Check the complete model designation, suffix markings, connectors, housing, and visible signs of damage. Compare the module with the unit being replaced and confirm the intended host assembly.
2. Live Rig Testing
   Where compatible Yokogawa equipment and approved procedures are available, check startup behavior, power-supply status, and the operation of the associated control unit. A standalone power-on check does not establish compatibility with every FCU, FIO node, or repeater configuration.
3. QA & Anti-Static Packaging
   Handle the module with suitable ESD precautions. Protect its dedicated connector and enclosure from electrostatic discharge, dust, moisture, and impact during storage and transportation.
4. Global Logistics & Export Compliance
   Confirm the destination, shipping method, documentation requirements, and applicable customs classification before dispatch. Pack the module securely for international air or sea freight and provide tracking information after shipment.

Technical Pitfalls & Integration Warnings

1. Host Unit Compatibility

The is designed for specific Yokogawa assemblies, including designated FCUs, FIO Node Units, and optical ESB bus repeater units. Do not assume that it fits every Yokogawa rack or controller. Confirm the host-unit model and applicable installation manual before ordering.

2. Input Voltage Mismatch

The is specified for 220–240 V AC input, with a ±10% tolerance. Do not substitute the PW481 or PW484 based on physical similarity: these models have different input power requirements. Applying an incompatible supply can prevent operation or damage the equipment.

3. Redundancy and Slot Configuration

For a dual-redundant configuration, Yokogawa specifies two identical power supply modules with matching model codes. Installation positions depend on the host unit; P1 is used for a single-module arrangement where specified, while P1 and P2 are used for dual redundancy. Verify the actual chassis layout before installation.

4. Revision Identification and ESD Handling

Do not assume that suffixes or revision markings are interchangeable. Confirm the complete model code and applicable environmental requirements before replacing the module. During unboxing, use ESD-safe handling and avoid touching exposed connector contacts.

Frequently Asked Questions (FAQ)

Q1: What is the Yokogawa -50 S2 used for?

It is an AC input power supply module for designated Yokogawa control-system assemblies. Its documented applications include compatible field control units, FIO Node Units, and optical ESB bus repeater units.

Q2: What is the input voltage of the ?

The accepts 220–240 V AC ±10% at 50/60 Hz ±3 Hz. Verify the supply requirements and wiring instructions for the actual host unit before installation.

Q3: Can the be used as a standalone 24 V DC power supply?

It should not be treated as a general-purpose standalone power supply. Yokogawa specifies it as a dedicated module for compatible system assemblies and does not provide universal standalone output ratings for this purpose.

Q4: Does the support redundant operation?

Yes. Two identical compatible power supply modules can be installed in the designated positions to configure dual-redundant power. The host-unit documentation determines the correct installation arrangement.

Q5: Can the be replaced while the system is running?

Do not assume live replacement is permitted in every installation. Check the host-unit maintenance procedure, redundancy status, and consequences of removing the module. Follow the site’s approved procedure before disconnecting or replacing the power supply.

Q6: What information should I provide when requesting a quotation?

Provide the complete model number, a clear nameplate photo, required quantity, destination country, and host-unit model if available. These details help confirm the correct module and reduce the risk of ordering an incompatible version.

Q7: What is the international delivery lead time?

Lead time depends on confirmed stock, condition, inspection requirements, and destination. Contact us to confirm availability and the estimated dispatch date before placing an order.
