The ABB 3ADT218567S0234 is a DCS880-S02-3300-07R DC converter, a 4-quadrant regenerative unit rated for 690 VAC input and 3300 A continuous output. H8 frame size means this is the large-footprint chassis variant — expect a cabinet cutout sized for the DCS880 family's high-current builds, not a panel-mount module. The 82 dB(A) sound level is audible in a control room without enclosure damping; plan for a separate drive room or acoustic hood if the installation is near operator stations.
Analog I/O and environmental limits
Three analog inputs and two analog outputs are onboard — enough for a speed reference plus a tachometer feedback and two process signals (e.g., current and torque), but not for multi-axis coordination. The unit is rated for 5 to 95% relative humidity (non-condensing) and 50 Hz line frequency. Auxiliary terminals carry IP00 protection per IEC 60529 and IEC 60947-1, meaning they are live when the main power is on — all field wiring at the aux terminal strip must be behind a locked panel door or in a separate enclosure.
