Product Overview

The PW301/100 TO is a high-reliability AC/DC power supply module designed for Yokogawa CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). It provides stabilized 24 V DC power to Field Control Stations (FCS) and associated hardware, ensuring continuous and reliable operation in industrial environments.

Engineered for maximum availability, the PW301/100 TO supports dual-redundant configurations, allowing parallel operation with an identical module to maintain uninterrupted process control. Its hot-swappable design and integrated protection circuits make it ideal for 24/7 operation with minimal maintenance downtime.

Technical Specifications

Core Functional Features

• Hot-Swap Capability: Replace the module while the system remains powered, ensuring uninterrupted process control

• Fault Monitoring: Front-panel indicators and diagnostic contacts alert the DCS maintenance station of input or internal failures

• Circuit Protection: Integrated high-speed fuses protect both the module and downstream logic cards from overcurrent or short-circuit events

• Variant-Specific Design: The "/100 TO" suffix indicates a specific hardware version optimized for 100 V AC inputs and customized terminal orientation for high-density cabinet integration

FAQ

What does the "/100 TO" designation mean?
It specifies the 100 V input rating and a particular terminal orientation (TO) for convenient wiring in dense control cabinets.

Is the PW301/100 TO compatible with both CENTUM VP and CS 3000?
Yes. The module can be used across multiple generations of CENTUM hardware, provided the power supply nest/backplane supports the PW301 form factor.
