Honeywell's September 2021 HPM service spare-parts table lists 51401635-150 as the obsolete High-Performance Comm/Control communications/control card in the HPMM card set. Confirm the complete installed execution, receiving card file, related I/O Link card and site migration plan before replacement.
The Honeywell R690 HPM High-Performance Process Manager Service guide identifies 51401635-150 in its conformally coated ORU spare-parts table. The exact row calls it a High-Performance Comm/Control communications/control card and marks that execution obsolete. The same service excerpt explains that the HPMM card set comprises a Comm/Control card, a High-Performance I/O Link card and a UCN Interface module in a card file. These are documented relationships, not a claim that the entire set is included in an order for this single card.
Before buying or servicing an obsolete HPMM spare, compare the full physical marking, hardware and firmware revisions, receiving card file, companion I/O Link and UCN modules, and original plant configuration. The service excerpt also lists a later communication/control part, but this page alone is not a universal interchangeability authorization. Use the site's Honeywell migration or replacement instructions. Record the original card, installed position and diagnostics before isolation. After a verified exchange, follow approved restart procedures and test all affected control and communication functions. Confirm weight and dimensions from final packing.
Honeywell's HPM service parts table gives the exact part number and identifies its role as a communications/control card. The row is within the conformally coated HPM ORU list and marks this execution obsolete. Verify the supplied full label and hardware revision; a family label alone is not a complete order match.
The guide describes HPMM card files and a card set that includes the communications/control card, I/O Link card and UCN Interface module. These components have different roles and are not bundled automatically. Check the physical file, installed companions, connectors and site configuration before selecting a replacement.
The reviewed Honeywell excerpt proves exact-model identity and historical obsolete status. It does not give a complete modern substitution matrix, package weight, packed dimensions or final supplied condition. A later-listed part number should not be treated as universally interchangeable without Honeywell and site-specific revision and migration evidence.
Confirm 51401635-150 on the actual card and compare revision, receiving HPMM file and installed companion modules with the approved service record. Honeywell's R690 parts table supports the High-Performance Comm/Control designation and obsolete lifecycle status. It does not by itself authorize a replacement with any other suffix. Preserve original firmware, network and I/O Link configuration records before service.
Document the installed slot, connector seating, adjacent I/O Link and UCN Interface modules, current alarms and baseline operation. Follow approved isolation, ESD handling and Honeywell HPM service procedure. Fit only a fully qualified card or an explicitly approved migration assembly. After restart, verify HPM diagnostics, communications, regulatory and logic control paths affected by the work, and retain acceptance evidence.
