PW442-10 | Yokogawa PW400 Series Power Supply Module

The Yokogawa PW442-10, also identified by the base model PW442, is an AC power supply module intended to provide electrical power for industrial control hardware. Its input is specified as 100 to 240 VAC at 50/60 Hz in the supplied description. The exact DC output ratings, current capacity, and system compatibility require confirmation against the manufacturer documentation for this model.

Hardware Specifications

DCS Power Supply and Electrical Interface

The PW442-10 is described as an AC-input power supply module. Before integration into a Yokogawa control system, verify the rated input range, output voltage rails, output current capacity, connector pinout, and applicable system hardware configuration using the official datasheet.

Do not assume that the 24 VDC and 5.1 VDC outputs listed in secondary descriptions are both available on this specific model. These ratings require confirmation from a model-specific manufacturer source.

Frequently Asked Questions

Q: What input voltage does the PW442-10 support?

A: The supplied description lists 100 to 240 VAC at 50/60 Hz. Confirm the allowable input range and wiring requirements against the manufacturer documentation before energizing the module.

Q: What are the rated DC outputs and maximum current?

A: The supplied description mentions 24 VDC and 5.1 VDC but does not establish the exact output configuration or maximum current. Check the model-specific datasheet and system power budget before connecting loads.

Q: Can the PW442-10 be replaced or installed while the system is energized?

A: Hot-swap capability is not established by the supplied information. Follow the applicable Yokogawa system maintenance procedure and isolate power when required before removing or installing the module.

Field Installation Guidelines

• Verify the complete model number and hardware revision against the equipment bill of materials.
• Confirm input voltage, frequency, protective earthing, and terminal assignments before wiring.
• Check the manufacturer's installation manual for mounting orientation, ventilation clearance, and connector requirements.
• Route AC input wiring separately from low-level analog signal and communication cables where practical.
• Maintain protective earth continuity and follow the cabinet grounding design.
• Verify the module's DC output ratings and connected load requirements before applying power.
• Do not perform energized removal or replacement unless the manufacturer explicitly permits that procedure.
• After installation, check the module status indicators and measure the specified output voltages using the approved commissioning procedure.
