Honeywell CC-SCMB05 C300 / PCNT05 Memory Backup Module

A dedicated memory-backup assembly for the Honeywell PCNT05 controller platform, supporting controller data retention during power-loss recovery.

Engineered for
controller continuity

CC-SCMB05 is positioned within the PCNT05 memory-backup architecture, providing the backup function required for power-loss recovery.

When memory
continuity matters

In a process-control environment, an unexpected controller power interruption can turn a short electrical event into a longer recovery task.

The key engineering checkpoint is whether the installed controller is the PCNT05 platform. Honeywell states that PCNT05 requires the CC-SCMB05 memory backup module.

For a spare-part purchase, confirm the complete part number, required quantity, destination and required date before quotation.

We combine multilingual communication, structured order tracking and international parts handling to make difficult automation-part sourcing easier to manage.

Because PCNT05 uses the newer CC-SCMB05 memory-backup arrangement. Honeywell states that CC-SCMB05 is required for PCNT05 and that the older CC-SCMB02 is not compatible with PCNT05.

No for PCNT05 applications. The two assemblies should not be treated as interchangeable; Honeywell specifically states that CC-SCMB02 is not compatible with PCNT05.

First establish whether the controller is the PCNT05 generation and confirm the associated IOTA and system configuration. The memory-backup requirement should be checked against the actual controller generation rather than assumed from the C300 family name alone.

The assembly is part of the controller's power-loss recovery arrangement. If a plant waits until a controller fault or modernization shutdown occurs, the absence of the required spare can extend the maintenance window.

Provide the complete CC-SCMB05 part number, required quantity, destination, required date and the machine/system in which the assembly will be installed. These details help reduce the risk of quoting the wrong controller generation or an unsuitable substitute.
