FANUC Series 30i, 31i and 32i control units
The 30i family — 30i, 31i and 32i in Model A and Model B forms — is the higher-end control line in this catalogue. Replacement units are identified by A02B number and model, and this page groups the line's ordering points.
Series 30i, 31i and 32i Model A and B
The seller publishes the line as three series sharing one page of the family tree: Series 30i, 31i and 32i, each in Model A and Model B. The three series are close relatives, not synonyms — a 31i unit is not a 30i unit — and the model letter travels with the series in the unit's identity. Replacement ordering runs on the A02B number from the fitted unit, with the series and model confirming the match; the A02B series page collects the control numbers the catalogue names across all generations.
Because these controls sit on higher-value machines, their inquiries more often concern the satellites than the control unit itself: a board, a display, an I/O unit. Those families are generation-sensitive, which is why the generation question comes first on this page.

Confirming the generation on the machine
The 30i family and the 0i family are confused often enough that the blog carries a dedicated guide: 0i versus 30i generations shows where each marks its series on the unit. For a machine with a swapped or upgraded control, the fitted unit's label decides. Quote the label's series and A02B number together; where they appear to disagree, say so rather than resolving it silently, because the desk would rather reconcile the two than ship against the wrong one.
Repair routes for 30i-family units
Control units and their boards from this line are repair candidates, and the test bench diagnosis is the usual first step for an intermittent control fault, where a blind unit swap is the expensive guess. A buyer weighing a shelf unit against a bench repair for the same control can ask for both answers in one message, with the symptom and the machine's working state described as found.
