Application-Specific FAQ
Q: What is the difference between AAM11-S2 and AAM11-S1?
A: The AAM11-S2 provides 16 analog input channels per module, while the AAM11-S1 provides 8 channels. Both accept 4–20 mA current and 1–5 V voltage signals and are interchangeable within the same FCS slot.
Q: Is this module compatible with CENTUM CS 3000?
A: The AAM11 series is designed for CENTUM VP. For CS 3000 compatibility, please contact us — we can advise on equivalent or cross-compatible modules.
Q: Can this module be used in a SIL 2 safety loop?
A: The AAM11 is a standard process I/O module. For SIL-rated safety instrumented systems, Yokogawa’s ProSafe-RS platform should be specified. Contact us for guidance.
Q: Do you provide a warranty?
A: Yes. All units carry a minimum 90-day functional warranty. Extended warranty options are available — please inquire at time of order.
Q: Can I get a datasheet or Yokogawa documentation?
A: Yes. Email us with your model number and we will provide the relevant Yokogawa technical manual or GS sheet.
