Application-Specific FAQ
Q: Is the AAR181-S53 S2 compatible with CENTUM CS 3000 as well as CENTUM VP?
A: Yes. The AAR181 series was originally developed for CENTUM CS 3000 and is forward-compatible with CENTUM VP I/O subsystems. Confirm your FCS firmware version with our team for full compatibility assurance.
Q: Can this module be used in a Safety Instrumented System (SIS)?
A: The AAR181-S53 S2 is a standard DCS I/O module. For SIL-rated SIS applications, YOKOGAWA’s ProSafe-RS platform with dedicated safety I/O modules is the appropriate solution. We can source ProSafe-RS components as well.
Q: What is the difference between the S53 and other AAR181 suffix variants?
A: Suffix codes on YOKOGAWA modules typically denote hardware revision, channel configuration, or regional certification variants. Contact us with your existing system’s I/O drawing to confirm the correct suffix for your application.
Q: Do you provide YOKOGAWA factory calibration certificates?
A: Factory calibration certificates are available for new-in-box units. For surplus or refurbished stock, third-party calibration reports can be arranged upon request.
Q: What is the lead time for this module?
