Power Supply Function

The PW701 provides the electrical supply required by the FCS hardware. Its role is to support the operation of installed control system components through the station's internal power distribution arrangement.

When identifying a replacement, the input voltage and the original FCS configuration should be checked against the installed module. A matching model number alone does not establish compatibility with every Yokogawa control station.

Frequently Asked Questions

Q: What is the main function of the Yokogawa PW701?
