Features:

  • Pairs the K4LCN-4 board designation with Honeywell part 51402755-100.
  • Provides the processor and Local Control Network foundation in History Module hardware.
  • Works with a separate generation-matched mezzanine memory board.
The combined K4LCN-4 and 51402755-100 identity defines the later K4LCN processor board execution.

It provides the LCN processing interface for the supported History Module hardware.

Match the mezzanine memory, node address, chassis revision and complete board labels before service.

Legacy K4LCN supply is verified against processor, memory and History Module configuration.

  • Maintain LCN processing within a Honeywell History Module node.
  • Support the documented processor-to-mezzanine memory relationship.
  • Restore a node after confirming address, chassis and board revision records.
  • The processor uses a separately identified mezzanine memory assembly.
  • Honeywell documents 51201795-400 as the 4 MW memory companion in this service context.
  • Memory seating and identity must be preserved during a board exchange.
  • The board provides the processor relationship to the Local Control Network node.
  • Node address and chassis configuration determine its installed role.
  • The processor board is not a stand-alone controller outside the History Module assembly.
  • 51402755-100 identifies the later K4LCN processor-board part number.
  • Earlier 51401946-100 hardware must not be assumed equivalent.
  • Primary and secondary revision labels must be recorded before an update or replacement.
Description
K4LCN-4 51402755-100 is listed by Honeywell as a K4LCN circuit board in the History Module service assembly. The board provides the processor and Local Control Network-facing foundation used by the module's storage and node-management functions.

The K4LCN board is paired with a separate mezzanine memory board. Honeywell lists 51201795-400 as the 4-megaword memory board for the 51402755-100 generation, so the supplied label K4LCN-4 should be checked against both the motherboard and installed memory assembly.

The service procedure includes LCN node-address selection on the K4LCN board. The selected address identifies the History Module on the Local Control Network and must agree with the system configuration before the node is returned to service.

Technical notes
K4LCN-4 51402755-100 requires the correct mezzanine memory and node configuration; the earlier 51401946-100 board must not be treated as identical.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What hardware role does Honeywell K4LCN-4 51402755-100 perform?
It is the K4LCN processor board used in documented History Module hardware on the Local Control Network.
Which memory assembly is associated with Honeywell K4LCN-4 51402755-100?
Honeywell service information identifies the separate 51201795-400 4 MW mezzanine memory in this hardware context.
Why should Honeywell K4LCN-4 51402755-100 not be confused with 51401946-100?
The latter is an earlier K4LCN board identity; revision and node compatibility must be established rather than inferred.
What node settings matter when servicing Honeywell K4LCN-4 51402755-100?
The History Module chassis, node address, memory companion and LCN configuration should be recorded before removal.
Can the processor board be tested independently of the Honeywell History Module?
Its intended function depends on the supported chassis, memory and LCN node environment, so stand-alone substitution is not appropriate.
Which photographs are useful for a Honeywell K4LCN-4 51402755-100 RFQ?
Provide clear processor and mezzanine labels, chassis identification, node information, quantity, condition requirement and destination.
