CARDASSIAN REPLICATOR
This is the working Cardassian Replicator used in Ops on DS9, it lights up when plugged into a wall outlet. This replicator was used throughout all seven seasons of DS9.
The two screencaps above are from the episode "Civil Defense", where an old Cardassian Security program causes the replicator to replicate a device that shoots at any non-Cardassians in Ops.
