Description
Kongsberg Simrad 382-102974J SSIB Sensor & Solenoid Interface Board
Product Introduction
The Kongsberg Simrad 382-102974J is a specialized Sensor & Solenoid Interface Board (SSIB) associated with Kongsberg Simrad marine automation equipment. Available part records identify the board as 382-102974, with 382-102974J and 382102974J appearing as alternate representations of the same identification. The board is associated with an ACS Automatic Control System, placing it in the vessel automation and control interface layer rather than in a general-purpose PLC product family.
The functional designation SSIB indicates that the board provides an interface between the ACS control system and field devices involving sensors and solenoids. This makes the board relevant to marine machinery automation where discrete field devices and monitored sensor signals must be connected to the vessel’s control architecture. The available technical record specifically describes the 382-102974 as a Sensor & Solenoid Interface Board and associates its installation with a designated ACS controller rack.
For procurement, the Kongsberg Simrad 382-102974J should be treated as a configuration-specific marine automation PCB. Available physical-part records show SSIB Rev. D, which means revision matching is important when replacing an installed card. One listing also places 382-102974 alongside 382-102973, although the exact relationship between those two board numbers is not sufficiently documented to call them interchangeable.
The available sources do not provide enough reliable information to state exact supply voltage, input/output channel count, signal ranges, isolation, or network protocol. Those parameters should therefore be confirmed from the original board markings, ACS system documentation, wiring drawings, and Kongsberg configuration records before replacement.

Main Features and Engineering Considerations
Sensor and Solenoid Interface
The defining characteristic of the 382-102974J is its SSIB designation. It is intended to interface field-level sensor and solenoid functions with the ACS control system. This makes it a system-specific interface card rather than a generic digital I/O module.
ACS System Integration
The board is associated with Automatic Control System (ACS) architecture used in marine automation. The correct replacement therefore depends on the host ACS hardware, cabinet arrangement, wiring, and software configuration. A card with a similar connector arrangement is not automatically an acceptable substitute.
Revision Control
Available physical listings identify a Rev. D version of the 382-102974 board. When purchasing a spare, record the complete board marking, revision, serial number, and any additional assembly number printed on the PCB.
Field Wiring Is Critical
Because this is a sensor and solenoid interface board, incorrect field wiring can have consequences beyond simple communication failure. Before removing the original board, document connector positions, terminal assignments, field-device references, and any jumpers or configuration components.
Do Not Confuse Related Part Numbers
382-102973 and 382-102974 frequently appear together in listings, but the available evidence does not establish that they are electrically interchangeable. Treat them as separate purchasing identifiers until the Kongsberg system documentation confirms otherwise.
Application Scenarios
- Kongsberg Simrad marine automation systems
- ACS Automatic Control Systems
- Vessel machinery control
- Marine sensor interfaces
- Solenoid valve control interfaces
- Shipboard automation cabinets
- Legacy Kongsberg/Simrad control-system maintenance
- Replacement of installed SSIB boards
Engineer’s Guide: Field Pitfalls
1. Match the complete part number.
Use 382-102974J, 382-102974, and 382102974J as search identifiers when sourcing, but compare the actual PCB marking before accepting a replacement.
2. Check the board revision.
A physical listing identifies a Rev. D version. Do not assume that a different revision has identical hardware behavior without checking the ACS documentation.
3. Verify the host ACS rack.
The board is system-specific. Confirm the rack position, backplane, connector arrangement, and associated controller before installation.
4. Preserve field wiring records.
Photograph every connector and record sensor/solenoid circuit identification before removing the original card.
5. Do not assume 24 VDC.
Although 24 VDC is common in marine automation, I could not verify the operating voltage for this exact board from sufficiently reliable documentation. Use the original system drawings or board documentation.
6. Do not treat 382-102973 as an automatic replacement.
The two numbers are associated in available listings, but their precise relationship is not sufficiently documented to establish interchangeability.
7. Test field circuits after replacement.
Check sensor feedback and solenoid operation individually before returning the vessel’s automatic control functions to normal service.
Frequently Asked Questions
What is Kongsberg Simrad 382-102974J?
It is a Sensor & Solenoid Interface Board (SSIB) associated with Kongsberg Simrad ACS Automatic Control Systems.
What does SSIB mean?
SSIB is used for Sensor & Solenoid Interface Board, describing the board’s field-device interface role.
Is 382-102974J a PLC CPU?
No. Available documentation identifies it as an interface board rather than a general-purpose PLC processor.
Is 382-102974J a Kongsberg marine automation component?
Yes. The available records identify the brand as Kongsberg Simrad and associate the board with ACS marine automation systems.
Is 382-102974 the same as 382-102974J?
Available records explicitly list 382-102974, 382102974, and 382-102974J as references for the same SSIB board family. The complete physical marking and revision should still be checked before procurement.
Can 382-102973 replace 382-102974J?
Not on the evidence currently available. The two numbers appear together in listings, but that does not establish electrical or functional interchangeability.
Procurement Note
For Kongsberg Simrad 382-102974J, procurement should focus on exact board identification and revision matching. Record the complete 382-102974J marking, any SSIB designation, PCB revision, serial number, and the host ACS equipment model.
I would not populate an ERP or product database with assumed voltage, channel count, signal ranges, or communication protocol for this board. Those specifications were not sufficiently documented in the sources available for verification. For a production vessel, the safest replacement check is the original board → ACS rack position → connector/wiring drawing → revision → replacement board test sequence.
