Product details

Acoustic and environmental fit

The 3ADT218521S0221: Sound level is listed at 66-70 dB(A). That is conversational noise — not silent, but not screaming. If this goes into a control room or a quiet production area, plan for ear protection signage or a separate drive cabinet. The operating humidity range of 5 to 95 % RH covers most indoor industrial environments without a de-rating curve to chase.

IP rating and enclosure requirement

Auxiliary terminals are rated IP00 per IEC 60529 and IEC 60947-1. They require a locked, ventilated enclosure for touch and debris protection.

Frequently asked questions

What is the frame size of this DCS880 converter?

Frame size H4. That determines the mounting footprint, gland plate layout, and enclosure volume needed for the 38 kg unit.

What is the sound level of this drive?

66-70 dB(A). Plan for ear protection or a separate drive cabinet if the drive is installed in a quiet area.

What IP rating do the auxiliary terminals have?

IP00 per IEC 60529 and IEC 60947-1. The terminals are not touch-safe; they must be housed inside a locked, ventilated enclosure.

How many analog inputs and outputs does it have?

Three analog inputs and two analog outputs are onboard, enough for a basic speed or torque control loop without an extra I/O module.
