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.

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.
