FAQ & Purchasing Guide

• Question: Can I mix RTD and POT sensors on the same AAR145-S00 module?
• Answer: Yes, the AAR145-S00 allows for individual configuration of CH1 through CH16. You can tailor each channel to either mode via software.
• Question: What is the maximum allowable wiring resistance for accurate measurement?
• Answer: The AAR145 supports up to 150 Ω per wire. Balanced 3-wire lead resistances are required to maintain ±150 mΩ accuracy.
• Question: How does the channel isolation benefit my Centum VP system?
• Answer: With 200V AC isolation between channels, it protects your I/O subsystem from cross-talk and damage if a sensor develops a high-voltage fault.
• Question: Is the AAR145-S00 hot-swappable?
• Answer: While the hardware supports it, check your Centum VP node documentation for safe online replacement procedures to avoid process trips.
• Question: Why choose the -S00 suffix over other versions?
• Answer: The -S00 is the standard, non-explosion-proof basic type. It is the most cost-effective version for general-purpose control rooms.
