Panel cutout and sampling speed
The PXF9ACC2-FVVA1 occupies a standard 1/4 DIN cutout — 96 x 96 mm — so it drops into any existing panel punch without adapter plates. If the loop you are tuning has a dominant time constant under one second, the 50 ms sample rate will track it; for slower loops the self-tuning algorithm averages over several samples anyway.
Lifecycle and procurement posture
The lifecycle stage is listed as current — Fuji Electric still produces this order code. That means the unit carries full factory warranty and documentation support; you are not buying into a last-time-buy window. For a panel builder or MRO planner, this simplifies the spares strategy: the PXF9ACC2-FVVA1 can be specified into a new build without planning a future migration.
