PLC 1772-M16 PLC-2 Core Memory Module

1772-M16 is a PLC-2 core memory module reference used as processor program-memory hardware. The complete label and installed processor documentation determine the applicable configuration and compatibility.

No. The suffix is part of the catalog identity, but an exact current public datasheet was not located. Confirm capacity and organization from the module label, core-memory assembly markings and the installed processor record before ordering.

Compatibility requires the exact PLC-2 processor model and revision, chassis arrangement, core-memory assembly, documented capacity and existing program configuration. A matching connector or appearance alone is insufficient.

1772-M16 and 1772-M8 are separate catalog references. Do not infer interchangeability from the shared product family; compare the complete labels, documented memory configuration, processor support and physical assembly.

Create and verify an approved program backup, record the active memory configuration, module position and processor revision, and follow the site power-down procedure. Replacement should proceed only after restoration requirements are understood.

A common mistake is selecting a module only by the M16 marking. The product entity, program-memory function, installed core-memory configuration and processor compatibility must all be confirmed before insertion or commissioning.

Send the full 1772-M16 nameplate, front and connector photographs, processor model and revision, chassis position, documented memory configuration, quantity and destination. This supports accurate identification and ordering.
