Features:

  • Identifies the replacement assembly by Honeywell part number 51402797-200.
  • Retains the supplied mounting bracket as part of the service configuration.
  • Requires host-node and connector verification before installation.
The ordering identity covers the board assembly and bracket configuration associated with part number 51402797-200.

Within a legacy Honeywell control installation, the assembly supports maintenance of an existing node rather than a change to the system architecture.

Record the removed board position, bracket orientation and connected harnesses before exchange so the replacement can be matched without disturbing adjacent hardware.

Availability is subject to Apter Power inventory and sourcing confirmation.
Verified resources for Honeywell 51402797-200: Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Supports like-for-like maintenance of documented Honeywell TPS control hardware.
  • Helps restore a service position when an installed board and bracket require replacement.
  • Provides a traceable spare for lifecycle planning in legacy process-control cabinets.
  • Preserve the existing LCN connector arrangement and cable routing recorded before removal.
  • Confirm every backplane and external connector against the installed node documentation.
  • Recheck shield and grounding continuity after the replacement board is seated.
  • Match the complete Honeywell part number before treating the assembly as interchangeable.
  • Compare bracket geometry, connector keying and host-slot position with the removed unit.
  • Validate the node hardware revision and maintenance records before commissioning.
  • Operate the assembly only within the enclosure limits specified for the host control cabinet.
  • Protect exposed circuitry from electrostatic discharge, moisture and conductive contamination.
  • Allow safe de-energization and controlled handling during removal and installation.
Description
The Honeywell 51402797-200 is an LCNP (Local Control Network Processor Card) built with a Motorola MC68040 CPU running at 33 MHz and equipped with 32 MB DRAM. It is designed as a plug-in processor board operating on a 24 VDC power supply, ensuring compatibility with Honeywell TDC 3000 and TPS systems.

This module is primarily used to establish communication between PC or GUS operator workstations and the Local Control Network (LCN). Within distributed control environments, the Honeywell 51402797-200 supports data exchange and system interaction between operator interfaces and process control networks.

The Honeywell 51402797-200 is supplied in a form factor designed for mounting with a bracket or card guide, allowing stable installation within system hardware racks. It is engineered to operate under industrial temperature conditions ranging from -10°C to +55°C, with storage capability from -40°C to +70°C.

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.
Why must the bracket remain part of Honeywell 51402797-200 identification?
The current service configuration is recorded as a board assembly with bracket, so mechanical fit must be checked with the electronics.
Which label comparison is required for Honeywell 51402797-200?
Match the complete part number on the board and confirm that the bracket belongs to the same removed assembly.
How should connector orientation be documented for Honeywell 51402797-200?
Photograph the installed connectors and cable approach before removal, then mark each harness by its original position.
What node record helps validate Honeywell 51402797-200 installation?
Use the cabinet location, host node designation and maintenance history as the baseline for the replacement.
Can a bare board automatically replace Honeywell 51402797-200 with its bracket?
Not without verification. Mechanical mounting, grounding, connector access and the exact ordering identity must still be compared.
What should be sent when requesting Honeywell 51402797-200 availability?
Provide the full part number, bracket photographs, host-system details, quantity and required delivery location.
