- Honeywell May 2025 bulletin names exact CC-SCMB05.
- Honeywell January 2025 bulletin says PCNT05 needs it.
- Older CC-SCMB02 is expressly incompatible with PCNT05.
Honeywell's May 2025 System Hints lists a new enhanced memory backup module, CC-SCMB05, among the features of its CC-PCNT05 C300 controller. A separate January 2025 bulletin says PCNT05 needs this module and states that older CC-SCMB02 is not compatible. Together these direct manufacturer references establish the module's identity and a specific compatibility boundary. They are short system bulletins, not a complete CC-SCMB05 component datasheet. Controller-level temperature, processing, network and I/O figures elsewhere in the bulletins must not be transferred to the backup module.
For procurement, identify the installed controller version, current module label, Experion release, redundancy arrangement and applicable site migration plan. Ask the supplier to confirm the physical CC-SCMB05 and any included retention hardware against the quotation. Do not substitute CC-SCMB02 merely because it looks similar or served an earlier C300 execution. Before service, record the original configuration and follow the Honeywell procedure for safe controller maintenance. After installation, verify module recognition, alarms and the site's approved backup and recovery checks without creating an unplanned process interruption.
The CC-SCMB05 Honeywell C300 PCNT05 Enhanced Memory Backup Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell CC-SCMB05 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
The May 2025 Honeywell bulletin calls CC-SCMB05 the new enhanced memory backup module for CC-PCNT05. This is an exact-model manufacturer statement. It identifies the role but does not quantify internal storage, electrical consumption or retention time. Check the complete supplied label and controller execution before ordering.
Honeywell's January 2025 System Hints says PCNT05 needs CC-SCMB05 and expressly states that older CC-SCMB02 is not compatible with PCNT05. Do not infer the reverse compatibility of CC-SCMB05 with older controllers. Confirm the installed C300 model, release and the approved upgrade or replacement procedure.
The linked official Honeywell bulletins establish the module's exact identity and the PCNT05 compatibility boundary. They do not publish exact backup duration, operating current, pack dimensions, gross weight or country of origin for the supplied spare. Such values require a component specification or actual-item evidence; none is invented here.
