PLC 1772-M8 PLC-2 Core Memory Module

1772-M8 identifies a PLC-2 core memory module reference. Its function is to provide program-memory hardware for a compatible processor; the exact module label, processor revision and documented memory configuration must agree before use.

Confirm the complete 1772-M8 label and the installed core-memory assembly markings, then compare them with the processor record. No exact current public datasheet was located, so an unverified capacity value should not be inferred from the catalog number alone.

1772-M8 belongs to the PLC-2 processor platform. Compatibility is limited by the exact processor model and revision, chassis arrangement, core-memory assembly and documented program configuration.

No. 1772-M8 should be treated as a core memory module reference, not as a CMOS RAM memory module. The catalog number, physical assembly and processor documentation must be matched rather than assuming interchangeability with a different memory technology.

Isolate power according to the site procedure, preserve an approved program backup, record the processor and chassis details, photograph the existing module and confirm the replacement label and core-memory configuration before installation.

A direct migration should not be assumed. A substitute must support the installed processor revision, memory architecture, required program configuration, physical fit and approved backup or restoration procedure.

Provide the complete 1772-M8 label, processor model and revision, chassis position, core-memory assembly photographs, required quantity and the documented memory configuration. These details allow the physical product, function and compatibility limits to be checked together.
