Product Description
The CP451-51 S2 is a high-efficiency central processing unit designed by Yokogawa for dedicated control tasks within the CENTUM VP distributed control system. Serving as a compact yet powerful logic solver, it manages data acquisition and real-time execution for specialized Field Control Units.
The “51” variant includes enhanced environmental protection, while the S2 hardware revision ensures modern component reliability and improved heat dissipation. Manufactured in Japan to industrial standards, the CP451-51 S2 provides a deterministic platform for critical process loops where space-saving and long-term durability are primary requirements.

Frequently Asked Questions
Q: What differentiates the CP451-51 S2 from the standard CP451-50 model?
A: The CP451-51 S2 includes ISA G3 conformal coating for corrosive gas resistance and features the S2 hardware update for improved internal efficiency and heat dissipation.
Q: Is this module hot-swappable?
A: Yes. When used in a supported redundant configuration within the Yokogawa backplane, it can be replaced without shutting down the entire station.
Q: Does it support Vnet/IP communication?
A: This module is primarily for localized bus communication. Integration into a Vnet/IP network requires a higher-level station controller or a specific communication bridge.
