The Siemens 39ACM24BEN is identified by Siemens in the APACS+ product context. Siemens identifies 39ACM24BEN as an APACS+ Advanced Controller Module with 4 MB memory. The additional 16139-215/1 marking is retained as part of this requested full identity, but its ordering or revision relationship is not established by the reviewed public Siemens documents.
