Frequently asked questions – expert advice

Can AI931N power 2‑wire transmitters?
No, AI931N has passive inputs. It does not supply loop power. Use an external power supply or choose AI930N with active inputs.
What HART data can I get?
You get up to 4 cyclic HART variables per channel (PV, SV, TV, QV) plus all standard HART commands via acyclic communication. Great for predictive maintenance.
Which base plate works with AI931N?
Any S900 base plate with Profibus DP backplane. Use TB820 for redundant communication or TB840 for standard. The module fits all.
Is hot swap really safe for electronics?
Yes, the S900 system has integrated disconnectors. You can remove or insert AI931N while the system is running without damage or data loss.
