Application-Specific FAQ
Q: Can the AAR145-S03 S1 be used with CENTUM CS 3000 as well as CENTUM VP?
A: Yes. The AAR145 series is compatible with both CENTUM CS 3000 and CENTUM VP platforms. Confirm the specific I/O bus revision with your YOKOGAWA system integrator.
Q: What is the difference between the S03 and other suffix variants (e.g., S04, S06)?
A: The suffix denotes the number of input channels and/or input type configuration. S03 typically indicates a specific channel count optimized for RTD/POT inputs. Refer to YOKOGAWA GS document for the full suffix matrix.
Q: Is this module suitable for 2-wire RTD connections?
A: The AAR145 supports 3-wire and 4-wire RTD configurations for optimal accuracy. 2-wire connections are possible but will introduce lead resistance error; consult your process engineer for acceptability.
Q: Can I replace this module online without shutting down the controller?
A: CENTUM VP supports online module replacement (hot-swap) for I/O modules. Confirm this capability is enabled in your system configuration before performing live replacement.
Q: Do you provide a warranty on this module?
A: We offer a 90-day functional warranty on all modules sold through Konmask.com. Extended warranty and on-site support arrangements are available — contact us for details.
