The Siemens 39VIMCCN is identified by Siemens in the APACS+ product context. Siemens identifies 39VIMCCN as an APACS+ Voltage Input Module; exact input ranges and channel count are not stated in the lifecycle appendix. The additional 16171-126/3 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.

In the installed system, it supports acquisition of voltage-based process signals for the configured APACS+ controller application and handles voltage inputs whose source, range, common, and isolation requirements must come from the exact Siemens module manual. Match /3 to the documented input range, source reference, and isolation arrangement before loop connection.
Important Notice: Use the complete 39VIMCCN 16171-126/3 code and verify the physical nameplate and current Siemens documentation before installation or replacement.
Apter Power 39VIMCCN 16171-126/3 Manuals and Guides
Important Notice: These are two separate Apter Power documents prepared from the manufacturer-published Siemens information named in each document. Confirm the physical nameplate, current Siemens documents, and host-system requirements before installation or replacement.
Voltage-input assembly /3
Match /3 to the documented input range, source reference, and isolation arrangement before loop connection.
Legacy DCS maintenance
Preserve both 39VIMCCN and 16171-126/3 in the service record.
Migration preparation
Capture configuration, drawings, and test evidence before redesigning the APACS+ function.
Read and follow the exact Siemens documentation and host-equipment instructions before use. Verify 39VIMCCN 16171-126/3 from the physical nameplate.
