Selection Notes
This push-in module pairs with the same 8-channel 2 A digital output card as the screw-terminal 6ES7921-5AD00-0AA0, but conductors clamp in at 0.5-1.5 mm² without a screwdriver. The single 16-pole IDC connector and one plug-in contact keep it dedicated to that output card rather than a 32-channel I/O module. Pick it for panels standardized on push-in wiring; pick the screw version where a wider conductor range or screw-terminal consistency with the rest of the cabinet matters more.
