The Delta DVP24XN01T is a DC Input L TYPE extension unit in the DVP Series, adding 24 I/O points to a DVP main processing unit. It is a current-lifecycle part, so it remains a standard BOM line for new panels and line expansions.
What the DC Input L TYPE means for fit
The 'L TYPE' designation on the DC input tells you this module uses a low-speed, sink/source DC input circuit — typical for pushbuttons, limit switches, and proximity sensors running at lower update rates. It is not a high-speed counter or encoder input; if your application needs fast pulse capture, you want a different input type (H TYPE) in the same family.
As an extension unit, the DVP24XN01T connects to the DVP main unit via the expansion bus cable and mounts on the same DIN rail. The 24 I/O points share the backplane power budget — verify the main unit's total expansion current limit before adding multiple extension modules.
