Product details

Analog I/O and environmental limits

The 3ADT218521S0142: Three analog inputs and two analog outputs are onboard for speed/torque reference and feedback loops — no option card needed for basic process control. Sound level is listed at 66–70 dB(A); plan for ear protection within a 1 m radius in a quiet control room.

Protection and terminal ratings

Degree of protection per IEC 60529, IEC 60947-1, and EN 60529: the auxiliary terminals are rated IP00 — meaning they are not touch-safe and must be enclosed in a panel or cabinet with at least IP2X on the outer door. The main power stage enclosure rating is not separately stated; assume the same IP00 unless the cabinet integration adds the barrier.

Frequently asked questions

What is the frame size of 3ADT218521S0142?

Frame size H4 — a floor-mount or heavy-panel frame, not a DIN-rail unit. At 38 kg it needs structural support.

What are the analog I/O counts on this DC converter?

Three analog inputs and two analog outputs are standard onboard, sufficient for speed reference and feedback without an expansion module.
