The 9954260 is a group input module and may not be avalible anymore. In mt TKE parts book I show the regular imput module as 9955549 and the output as 9954818. I was told told that IDEC does not procude parts for this PLC anmore but last I checked TKE still does have stock on the 2 non group modules I mentioned above as I ordered one of each a week ago.
