The 3ADT218521S0122: Acoustic noise sits at 66–70 dB(A), which is a standard industrial level — not silent, but not a siren. If the panel is near a quiet zone (office, lab), budget for an enclosure or remote mounting. The IP00 rating on the auxiliary terminals means the power terminals are unprotected against dust or touch — the converter must live inside a panel with a door or cover. The 5–95 % non-condensing humidity range is broad enough for most indoor industrial environments. Analog I/O: three inputs and two outputs are on board. That covers a speed reference and a couple of feedback signals without an add-on module.
