Kongsberg Simrad 382-083550 Microcon Control Module

Description

Simrad 382-083550

Product Introduction

The Simrad 382-083550 appears to belong to the older Simrad Norway Microcon family of marine electronic control hardware. However, the available records do not provide enough evidence to confidently define 382-083550 itself as a separate orderable PCB. Search results consistently identify 381-083550 as a Simrad Microcon PCB, while 382-083551 is repeatedly associated with that board as a related Microcon PCB or Harting interface designation.

This distinction is important when dealing with legacy marine automation equipment. A record can contain several board numbers representing a PCB assembly, mating interface, revision, or associated component. For example, available listings describe 381-083550 Rev. D as a Microcon PCB and associate it with 382-083551. One listing specifically calls 382-083551 the Microcon Harting component, while other records simply describe the combination as a Kongsberg/Simrad PCB.

Because I could not verify an authoritative technical document that directly identifies Simrad 382-083550, I would not assign unsupported voltage, channel count, communication protocol, or environmental ratings to this number. If the physical board actually reads 382-083550, the complete PCB marking, revision, and any associated 381-083550 or 382-083551 number should be captured before procurement. This is particularly important because 382-083551 is well documented in current spare-parts records, while the exact 382-083550 designation is not.

Technical Specifications

The identification of 381-083550 as a Simrad Microcon PCB and its association with 382-083551 is supported by multiple current spare-parts records.

Main Features and Engineering Considerations

Microcon Marine Automation Hardware

The available evidence places this part-number group within the Simrad Microcon family. This is legacy marine control hardware rather than a conventional modern PLC module. The equipment is therefore likely to depend heavily on its original system architecture and associated interface boards.

Part-Number Relationship Requires Verification

The most important issue is the relationship between 382-083550, 381-083550, and 382-083551. Current records repeatedly identify 381-083550 Rev. D as the Microcon PCB and associate 382-083551 with it.

A current spare-parts listing even describes the combination as “381-083550 MICROCON HARTING 382-083551 J”, suggesting that these numbers may refer to related PCB/interface elements rather than three independent interchangeable boards.

Do Not Substitute by Number Similarity

The difference between 382-083550 and 382-083551 is only one digit, but that does not make the boards interchangeable. In legacy marine electronics, a single suffix can identify a different PCB revision, interface, connector configuration, or assembly.

Revision Matching

Available records identify 381-083550 Rev. D. If your physical unit carries a revision marking, retain it in the procurement specification. A later or earlier revision should be accepted only after confirming compatibility with the installed Microcon system.

Application Scenarios

• Simrad marine automation systems
• Microcon control equipment
• Shipboard machinery automation
• Legacy Kongsberg/Simrad control systems
• Marine equipment refurbishment
• Replacement of obsolete Microcon PCB assemblies
• Vessel automation maintenance

Engineer’s Guide: Field Pitfalls

1. Verify the physical marking first.
The exact 382-083550 identifier is not as well supported as 381-083550 and 382-083551. Photograph the PCB label and silkscreen before ordering.

2. Check whether the board actually reads 381-083550.
Multiple current records identify 381-083550 Rev. D as the Simrad Microcon PCB.

3. Check for 382-083551.
This number is repeatedly associated with the Microcon PCB and is sometimes described as the Harting/interface portion.

4. Do not assume electrical specifications.
I could not verify the supply voltage, I/O configuration, or communication protocol for the exact supplied number from reliable technical documentation.

5. Match the board revision.
Rev. D is documented for the closely associated 381-083550 board. Record the revision from the installed hardware.

6. Preserve the complete assembly relationship.
Before replacement, document the controller/rack location, mating connectors, associated PCB numbers, and wiring. This is more useful than relying on a shortened part-number description.

Frequently Asked Questions

What is Simrad 382-083550?

The exact 382-083550 designation could not be independently confirmed from sufficiently strong technical documentation. It appears to belong to the Simrad Microcon marine-control PCB family, but the closely documented board is 381-083550.

Is 382-083550 the same as 382-083551?

Do not assume that. 382-083551 is repeatedly documented as a Microcon-related PCB/interface designation, whereas the exact 382-083550 identification is not established.

What is 381-083550?

Available records identify Simrad 381-083550 as a Microcon PCB, including a Rev. D version.

Is this a PLC module?

It should not be classified as a standard PLC I/O module based on the available evidence. The documented part-number group belongs to Simrad Microcon marine electronics.

What voltage does it use?

The supply voltage could not be reliably established from the sources reviewed. It should be taken from the original system documentation or board specification rather than assumed.

Procurement Note

For 382-083550, I recommend treating the part number as unconfirmed pending physical-board verification. The strongest available evidence points toward the related Simrad 381-083550 Microcon PCB, commonly associated with 382-083551.

For an RFQ or replacement request, provide:

• Exact PCB marking
• Complete Simrad/Kongsberg part number
• Board revision
• Any 381-083550 or 382-083551 marking
• Connector/Harting identification
• Host Microcon equipment model
• Photos of both sides of the PCB

That information will prevent a 382-083551 / 381-083550 / 382-083550 identification error, which is the main procurement risk with this item.
