PW442-10

The Yokogawa PW442-10 is a power supply module associated with Yokogawa's Wide Area Communication Router (WAC Router) hardware. It provides the power input function for the router assembly, which connects separate Vnet/IP domains through a wide area network (WAN). The PW442 power supply configuration uses a 220-240 V AC input at 50/60 Hz.

Function and System Role

The PW442 is identified in Yokogawa's AW810D Wide Area Communication Router documentation as one of three power supply module options:

• PW441: 100-120 V AC input.
• PW442: 220-240 V AC input.
• PW444: 24 V DC input.

These variants provide different incoming power requirements for the router hardware. The PW442 is therefore the AC input option for installations supplied from a 220-240 V AC source.

Power Supply Configuration

The AW810D hardware configuration uses two power supply modules for dual-redundant operation. The manufacturer also specifies two VI461 communication modules in this configuration. This redundancy arrangement applies to the complete router assembly, rather than establishing an independent redundancy capability for the PW442-10 module.

Frequently Asked Questions

Q: What is the difference between PW441, PW442 and PW444?

A: The primary difference is the input power source. PW441 uses 100-120 V AC, PW442 uses 220-240 V AC, and PW444 uses 24 V DC. The correct selection depends on the available power supply configuration.

Q: Is the PW442-10 used in a redundant power configuration?

A: Yes, the Yokogawa AW810D documentation specifies two power supply modules for its dual-redundant hardware configuration. The complete equipment configuration must follow the manufacturer's requirements.

Q: Does the PW442-10 supply power to the Vnet/IP communication network directly?

A: Its role is power supply within the router hardware. Vnet/IP communication is handled by the router's communication modules and associated network interfaces, not by the power supply module itself.
