Product Description

The PW701 is a specialized power distribution module engineered for the Yokogawa CENTUM VP control system architecture. It delivers high-current, stabilized DC power to the system backplane, meeting the demands of advanced processor modules and high-density I/O configurations. Designed with industrial-grade robustness, the PW701 provides superior voltage regulation and noise suppression, ensuring uninterrupted control logic execution and reliable field communications within cabinet environments.

Technical Specifications

Application Scenarios

The PW701 is commonly deployed in large-scale CENTUM VP installations where complex control strategies and dense I/O configurations are required. Typical applications include:

• Powering AFV30S and AFV30D Field Control Units

• Supporting racks populated with high-density analog I/O modules

• Supplying stable power to fieldbus communication cards in control-intensive systems

Its high output capability makes it especially suitable for control cabinets with elevated power demand.

Technical FAQ

Q: Can the PW701 be replaced while the system is running?
A: Yes. When the system is configured with redundant power modules, the PW701 supports hot-swap replacement, allowing maintenance without shutting down the control system or interrupting the process.

Q: Is the PW701 compatible with both AC- and DC-input FCU systems?
A: Yes. The PW701 functions as an internal power distribution module. The external input type (AC or DC) is determined by the FCU base unit or power entry configuration of the control station, not by the PW701 itself.
