More Information

Overview Manuals WDA Context Board Identity Service Boundary Applications

Features:

  • WDI service identity: Honeywell lists the part as the Winchester Drive Interface I/O circuit board.
  • CE build: the -200 version is the CE-compliant WDI board in the WDA-type History Module parts list.
  • Assembly boundary: its documented scope is the Winchester Disk Assembly history-module configuration.
The WDI board belongs to the disk-interface portion of a WDA-type History Module rather than the LCN or smart-peripheral-controller board positions.

Honeywell lists a separate -100 WDI board without the CE designation, so the complete -200 number is part of the configuration identity.

A useful service request names the WDA-type History Module, WDI position and exact board suffix together before any storage-interface work begins.

  • Module family: the parts-list scope is the Winchester Disk Assembly type History Module.
  • Board position: WDI identifies the Winchester Drive Interface I/O circuit-board function.
  • Service level: the board is listed as a replaceable item inside the WDA assembly.
  • Scope limit: the documented identity does not extend automatically to other History Module hardware types.
  • Exact suffix: -200 identifies the CE-compliant WDI build.
  • Related entry: -100 is separately listed as the non-CE WDI board.
  • Function name: retain Winchester Drive Interface in RFQ and receiving records.
  • Position evidence: compare the installed WDI location and complete label before exchange.
  • Drive-interface work: keep WDI diagnosis separate from LCN, controller and power-supply board work.
  • Cable record: identify the original drive-interface connections before removing the board.
  • Module record: link the board asset entry to the WDA-type History Module in which it operates.
  • Functional proof: use the History Module procedure to demonstrate storage-path recovery after exchange.
  • WDA History Module: restores the WDI I/O board position in the Winchester Disk Assembly configuration.
  • Drive-interface service: supports repair work already isolated to the WDI path.
  • CE configuration: preserves the -200 compliance build listed for the module assembly.
  • Legacy storage support: maintains the original interface architecture of the documented Honeywell History Module.
Description
In a WDA-type History Module, 51304903-200 serves as the CE-compliant Winchester Drive Interface I/O circuit board. The exact -200 identity distinguishes it from the separately listed -100 non-CE board in Honeywell’s replaceable-parts tables.

Service planning for 51304903-200 begins at the History Module assembly level, where the WDI board belongs to the drive-interface path rather than the controller or LCN circuitry. That location helps maintenance teams request the correct board when a disk-interface repair has already been isolated.

Because 51304903-200 is documented as a service-level part within the Winchester Disk Assembly configuration, its value lies in restoring the original module build—not in acting as a universal storage adapter. The installed WDA variant and board position should remain the governing fit references.

Technical notes
51304903-200 is the CE-compliant WDI I/O board for Honeywell's WDA-type History Module. The parts list also names 51304903-100 as a separate non-CE WDI build, so the common base number is not enough for selection. Keep the History Module type, WDI position and complete -200 suffix together on the service request.

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.
Is 51304903-200 appropriate when a maintenance order identifies the WDI position in a WDA-type History Module?
Yes, that is the documented service context. If the installed position is labeled SPC-2, LCN or controller circuitry instead, this WDI board is not the supported selection for that position.
Should a drive-interface symptom automatically lead a technician to replace 51304903-200?
No. The board belongs to the WDI path, but the parts list does not prove that every storage-path symptom originates on this board. Isolate the WDI position before purchasing a replacement.
What should receiving staff verify on a shipment labeled 51304903-200?
The label should retain the complete -200 number and the WDI or Winchester Drive Interface description. A -100 entry is a separately listed build and should not be booked as the same configuration.
Can 51304903-200 be treated as a general-purpose storage interface?
No. Its documented scope is the WDI I/O position in a WDA-type History Module, so the host assembly and service position remain part of the purchase decision.
When should a buyer place 51304903-200 on hold for engineering review?
Place the order on hold when the installed module is not a WDA type or the required position is not WDI. The available Honeywell parts listing does not establish use outside that boundary.
