The table for ABB AI931N separates verified family data from the configuration checks that still require a nameplate or ABB order record. Do not use a family rating as an unconditional guarantee for the installed unit.
Interface checklist
Before ordering AI931N, compare the installed terminal or connector arrangement, power source, mounting envelope and ancillary hardware with the current drawing.
Document the serial number and revision of AI931N where available. If a supplier proposes a substitute, obtain engineering acceptance for every changed interface.
Purchase decision
Specify ABB AI931N against a particular asset tag and duty. This unit is used to receive current-loop transmitter signals; record the intended circuit, process or equipment location before requesting a quote.
For AI931N, confirm passive loop power arrangement, HART access and S900 station fit. A matching short family name is not sufficient evidence of electrical, mechanical or software interchangeability.
Receipt inspection
On arrival, compare the supplied AI931N label and order code with the approved purchase description. Inspect packaging, terminals, seals and visible damage.
Do not install AI931N when the shipped suffix, control voltage, release or approval differs from the approved build; resolve that discrepancy before commissioning.
Site preparation
Plan the AI931N replacement under the facility isolation and permit rules. Preserve photographs, configuration files, settings and a diagnostic baseline before disturbing wiring.
Check enclosure temperature, grounding, segregation and protection coordination for AI931N. Record any accessory that is supplied separately rather than assuming it is in the device box.
Lifecycle handover
Keep ABB AI931N linked to its exact spares description, drawings and current manual revision. This helps the next maintenance team identify the same configuration rather than a superficially similar item.
Review the first operating period of AI931N for alarms, heating, drift or switching anomalies and update the asset record if the installed build differs from the original request.
Commissioning evidence
For AI931N, compare loop current and HART status channel by channel. Carry out only the tests approved for this device and the connected installation.
Save the as-left settings, measured results, witness and work-order reference for AI931N. Any temporary bypass or inhibited alarm must be removed before normal operation.

Information to send with an enquiry
Quote ABB AI931N exactly and include the asset tag, electrical or process duty, required accessories and delivery documentation.
For AI931N, request written confirmation of any deviation from the fitted unit before accepting an alternative.
