Yokogawa PW484-10 24 VDC Power Supply Module

The Yokogawa PW484-10, also cataloged under the PW484 base model, is a 24 VDC power supply module designed to provide electrical power to compatible Yokogawa control system hardware. It supports installation in designated power supply slots and can be used in dual-redundant configurations where the host unit supports this arrangement. The supplied information identifies the PW484-50 as an updated model.

Hardware Specifications

DC Power Input and Redundancy Configuration

The PW484-10 receives a nominal 24 VDC input and supplies power to compatible control system hardware through its designated connector. The stated input tolerance is +/- 10%. The supplied specifications list a maximum current of 5.5 A; this value should be checked against the official model-specific documentation before using it for power budget calculations.

For redundant installations, verify the host unit's supported power supply arrangement, slot assignments, and load requirements. Do not assume hot-swap capability or a specific switchover time without the applicable hardware manual.

Frequently Asked Questions (FAQ)

Q: Can the PW484-10 operate in a redundant power supply configuration?

A: The supplied information identifies dual-redundant operation using the P1 and P2 slots. Confirm the host unit's hardware configuration and compatibility before installation.

Q: Is the PW484-10 interchangeable with the PW484-50?

A: The supplied description identifies the PW484-50 as the updated model. Confirm electrical specifications, mechanical compatibility, and host system support before replacing the PW484-10.

Q: What input voltage does the PW484-10 require?

A: The supplied specifications state 24 VDC +/- 10%. Verify the permitted input range and current requirements against the official Yokogawa documentation.

Field Installation Guidelines

• Confirm the complete model number and connector configuration before installation.
• Verify that the host unit supports the PW484-10 and the intended power supply arrangement.
• Check the DC supply polarity and voltage before connecting the module.
• Inspect the connector and rack slot for damage, contamination, or loose contacts.
• For redundant configurations, verify both power supply paths and their specified load capacity.
• Follow the host system's approved power isolation procedure before removing or installing the module. Do not assume the module supports hot swapping.
• Route power wiring separately from noise-sensitive analog signal wiring where practical.
• Consult the applicable Yokogawa hardware manual for grounding, environmental limits, and commissioning procedures.
