          PRODUCT DESCRIPTION

          CP461-51 S2 Field Control Processor Module

          Yokogawa CP461-51 S2 is a CENTUM field control processor module built around a VR5532 processor running at 350 MHz with 128 MB of main memory. It is used in the documented field control unit arrangements, including A2FV50 installations accepting CP461 hardware style S2 or later.

          The processor uses the S9548FA backup battery. The documented battery-backed memory retention is up to 72 hours, with a minimum 48-hour recharge period. A duplex arrangement uses two identical CP461 modules; host-unit power consumption and I/O capacity are separate from the processor specifications.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate CP461-51 S2 within CENTUM VP CP461

          Match CP461-51 S2 to the installed CENTUM field control unit and its configured processor arrangement. The A2FV50 specification accepts CP461 S2 or later, and redundant operation requires two identical processor modules rather than a mixed CP461/CP471 pair.
          Retain the host project, processor pairing and bus-interface arrangement. The A2FV50 host supports the listed communication and N-IO/FIO couplers, but their node limits and input power are host specifications, not independent processor-board electrical ratings.
          Treat any CP461-to-CP471 migration as a separate approved service task. The manufacturer requires an authorized service engineer for that change and specifies EC401 S3 or later for the CP471 combination; replacing a like-for-like spare must not silently initiate that migration.

          Features:

          • A2FV50 applicable style: S2 or later
          • Duplex processor quantity: 2 identical CP461 modules
          • CENTUM VP CP461
          Use CP461-51 S2 only within the documented CENTUM VP CP461 arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace CP461-51 S2 within CENTUM VP CP461

          Record the full CP461-51 S2 label, host model, processor partner and current project before exchanging the module. Preserve the installed hardware style and applicable software configuration rather than selecting a spare only by the CP461 family name.
          Follow the field control unit maintenance procedure for the configured single or redundant arrangement. Protect the processor contacts and retain all project and backup information required to restore the installed control function.
          After replacement, verify the controller state, project consistency and the intended redundant processor condition. A CP471 offered in place of CP461 requires the separate manufacturer migration review and must not be treated as an automatic equivalent spare.

          Features:

          • CP461-51 S2 complete suffix
          • CP471 migration EC401 requirement: EC401 style S3 or later
          • CPU style and paired processor arrangement matched
          Use CP461-51 S2 only within the documented CENTUM VP CP461 arrangement and applicable installation instructions.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about CP461-51 S2

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Is style S2 of CP461-51 S2 listed for A2FV50?

            Yes. The A2FV50S/A2FV50D specification explicitly lists CP461 style S2 or later, which covers the style of CP461-51 S2.

          • Can CP461-51 S2 and CP471 form a mixed redundant pair?

            The documented host arrangement requires two identical modules with the same model code; do not treat a mixed CP461-51 S2/CP471 pair as the specified redundant configuration.

          • Does the A2FV50 input VA rating belong to CP461-51 S2?

            No. Input power in the A2FV50 specification is a host-unit figure, so it must not be copied as a standalone CP461-51 S2 processor rating.

          • Who may migrate CP461-51 S2 to CP471?

            The A2FV50 documentation requires CP461-to-CP471 replacement to be performed by an authorized Yokogawa service engineer, rather than by the user as a routine spare exchange.

          • Which EC401 style is stated for migrating beyond CP461-51 S2?

            The documented CP471 combination requires EC401 style S3 or later when reviewing a migration from CP461-51 S2.

          • What configuration must be retained before removing CP461-51 S2?

            Retain the complete CP461-51 S2 identification, host configuration, matched processor information and project backup required by the field control unit maintenance procedure.

          • What should a distributor preserve in a CP461-51 S2 offer?

            Offer CP461-51 S2 in full, including style S2, and distinguish a like-for-like spare from a CP471 migration. State the supplied scope and delivery separately.

          • Should a customer order one or two CP461-51 S2 modules?

            The required quantity depends on whether the customer needs one CP461-51 S2 replacement or a matched redundant pair. Confirm the installed processor arrangement before quoting the quantity.
