      Yokogawa DCS & Safety System Spares

      Keep your Yokogawa enquiry tied to the installed system. Send the full model, suffix and style code for control modules, I/O, power supplies or communication units. We supply new, unused parts, with availability and packaging confirmed for each quotation.
      BUILT AROUND YOUR INSTALLED SYSTEM

      Start with the Yokogawa label, then the system

      CENTUM VP is a distributed control system; ProSafe-RS is a safety instrumented system. Identify the platform on site, then record the complete module code and its terminal or cable arrangement. For older CENTUM equipment, include the system generation so your enquiry stays specific. The header and overview are studio illustrations based on product photos; request photos of the offered item.

          COMMON PARTS QUESTIONS

          Answers before you order

          Review the questions below for guidance on product identification, condition, warranty and delivery. Contact our team for details specific to your equipment or order.
          Ask our team a question
          • 01

            What should I send for a Yokogawa spare-parts quotation?

            Send the complete model and suffix code, any option codes, the style or revision printed on the label, and the quantity. Add a clear label photo and identify the installed system. If the code is incomplete, mark the uncertain characters rather than choosing a similar-looking module.
          • 02

            Can a similar CENTUM or ProSafe module replace the one installed?

            Do not treat appearance or a matching base model as confirmation of suitability. CENTUM VP and ProSafe-RS serve different system roles, and the selected item must match the applicable hardware and connection requirements. Have your responsible engineer check the exact code against the relevant Yokogawa documentation before ordering.
          • 03

            What condition and supporting information should I confirm?

            Apter Power is an independent supplier, not an authorized Yokogawa distributor. Our supply policy is new, unused parts. Ask the quotation to identify the offered item, packaging and any available inspection records, together with the warranty terms. Confirm any required document or test scope before purchase.
          • 04

            How should I plan an urgent Yokogawa delivery?

            Provide the destination and the date the item is needed on site. Ask for current availability, the proposed dispatch date and the transport option for that exact reference. Agree these details before payment; a catalogue listing alone does not confirm immediate stock or a same-day shipment.
