Description
Kongsberg Simrad 382-083602 Receiver Board
Product Introduction
The Kongsberg Simrad 382-083602 is an RX receiver board used in Kongsberg Maritime’s Simrad SPT and MPT underwater acoustic transponder systems. Kongsberg’s technical documentation explicitly lists part number 382-083602 as the “Rx board” in multiple transponder assemblies. It is installed together with the 382-083607 Tx board and 382-083551 microcontroller board, forming the principal electronic building blocks of the transponder.
The Kongsberg Simrad 382-083602 is not a general-purpose PLC input module or conventional marine automation I/O card. Its function is tied to the acoustic receiver section of the transponder. The same receiver-board part number appears across several SPT/MPT 31x configurations, including SPT 319, SPT 331/R, MPT 316/DT EEx, and other transponder variants. Kongsberg documentation also lists 382-083602 as the receiver board for the TTC 400 unit, where it is identified as an RX Receiver board MUTRAN.
From a maintenance perspective, this is a useful example of why the complete host-equipment model matters. The receiver PCB is shared across several Kongsberg transponder platforms, but the surrounding electronic chassis, transducer, transmitter board, battery arrangement, housing, and other system components vary by model. Kongsberg’s documentation shows the 382-083602 as a replaceable main module, generally with one receiver board installed per applicable transponder.

Main Features and Engineering Considerations
Dedicated Acoustic Receiver
The primary role of 382-083602 is reception of the acoustic signals used by the associated Kongsberg/Simrad transponder. It therefore belongs to the RF/acoustic electronics section of the equipment rather than the vessel’s conventional PLC or DCS layer.
Used Across Multiple Transponder Platforms
Kongsberg documentation shows the same receiver board in several SPT/MPT 31x-series transponder configurations. For example, the SPT 331/R parts table lists 382-083602 as the Rx board, while the SPT 319 and MPT 319 configurations use the same part number.
This cross-platform use is helpful when sourcing a spare, but it does not mean every 382-083602 board is automatically suitable for every transponder. The host assembly still needs to be confirmed.
TTC 400 Application
Kongsberg’s TTC 400 manual independently lists 382-083602 as the RX Receiver board MUTRAN. The same parts table identifies 382-219490 as the transmitter board, 382-219335 as the 16 MHz microcontroller board, and 382-098602 as the 48 VDC/1 A power supply.
This is useful when the replacement board is being sourced from a TTC 400 installation rather than an SPT/MPT transponder.
Part-Number Relationship
The associated 382-083551 is the microcontroller board, while 382-083607 is the transmitter board in the SPT/MPT 31x-series documentation. These boards should not be confused with one another during procurement.
Application Scenarios
- Kongsberg Simrad SPT 31x-series transponders
- Kongsberg Simrad MPT 31x-series transponders
- SPT 319 transponder systems
- SPT 331/R transponder systems
- MPT 316/DT EEx transponders
- Kongsberg TTC 400 equipment
- Underwater acoustic positioning systems
- Marine transponder maintenance and refurbishment
Engineer’s Guide: Field Pitfalls
1. Do not classify it as a PLC I/O board.
Kongsberg identifies 382-083602 specifically as an Rx receiver board.
2. Identify the host equipment before replacement.
The board is used across multiple transponder configurations, but the surrounding chassis and transducer arrangement differ.
3. Check the transmitter board separately.
In SPT/MPT 31x systems, 382-083607 is documented as the TX board, while 382-083602 is the RX board.
4. Check the microcontroller board.
The associated 382-083551 is the microcontroller board. Do not substitute it based on physical similarity.
5. Do not assign a generic supply voltage to the bare receiver PCB.
The system manuals identify the board’s function but do not provide enough information in the reviewed sections to establish its standalone supply requirements.
6. Check the transponder housing and sealing condition.
The environmental protection of the complete underwater transponder comes from the complete mechanical assembly. A replacement PCB by itself does not establish an IP or pressure rating.
7. Perform functional acoustic testing after replacement.
A receiver-board replacement should be followed by the appropriate transponder test procedure rather than only checking that the board powers up.
Frequently Asked Questions
What is Kongsberg Simrad 382-083602?
It is an RX receiver board used in Kongsberg/Simrad marine acoustic transponder systems. Kongsberg’s own documentation identifies it directly as the Rx board.
What systems use 382-083602?
It is documented in multiple SPT and MPT 31x-series transponders, and Kongsberg also lists it as the RX Receiver board MUTRAN in the TTC 400.
Is 382-083602 the transmitter board?
No. In the SPT/MPT 31x documentation, 382-083607 is the TX board and 382-083602 is the RX board.
Is 382-083602 the same as 382-083551?
No. Kongsberg identifies 382-083551 as the microcontroller board and 382-083602 as the receiver board.
Is 382-083602 used in TTC 400?
Yes. Kongsberg’s TTC 400 manual lists 382-083602 — RX Receiver board MUTRAN as one of the main modules.
Procurement Note
For Kongsberg Simrad 382-083602, the identification is considerably stronger than for many legacy PCB numbers because Kongsberg’s own manuals explicitly list the part number and function. The correct technical description is RX Receiver Board.
For purchasing, retain the complete 382-083602 number and identify the host equipment—such as the SPT/MPT transponder model or TTC 400. Also record the PCB revision, because the documentation establishes the function and part number but does not establish that every historical hardware revision is interchangeable.
Do not copy generic voltage, channel-count, IP-rating, or environmental specifications from unrelated Kongsberg boards. For this component, the receiver-board function and exact host-system compatibility are the specifications that matter most.
