Description
Product Overview
The Kongsberg RMP400 603129 is a remote multi-purpose I/O unit designed for marine automation systems. It provides an interface between field-level signals and a vessel’s wider control architecture, supporting distributed monitoring and control functions. In a typical marine installation, remote I/O equipment helps bring signals from machinery, sensors, and control devices into the automation system without requiring every field connection to terminate directly at the main controller. The exact input/output functions available depend on the installed hardware revision and system configuration.
The Kongsberg RMP400 603129 is associated with Kongsberg maritime automation and vessel-control applications, including machinery monitoring and dynamic positioning installations where the system design specifies this unit. Available technical listings identify an isolated RS-485/RBUS communication interface and a nominal 24 VDC supply, with a reported supply range of approximately 18–31.2 VDC. These values should be treated as reference data until confirmed against the original documentation for the installed revision. Do not infer a complete channel count or assume every RMP400 version has identical input and output characteristics.
When replacing a Kongsberg RMP400 603129, match more than the base model number. Units have been listed with different revision identifiers, including 2.1.x, 2.2.0, 2.3.0, and D1. The revision and serial-number markings should be recorded before ordering because compatibility depends on the host system, interface configuration, and application requirements. Confirm the connector layout, power requirements, communication wiring, and configured I/O functions against the vessel’s drawings and maintenance records. For marine automation, a physical match alone is not sufficient evidence that a replacement can be commissioned safely.
Product Introduction
Marine control-system maintenance often requires replacing a remote I/O unit without changing established field wiring or vessel-control logic. The Kongsberg RMP400 603129 serves as a distributed I/O interface for compatible marine automation installations, with an isolated RS-485/RBUS interface identified in available product references.
Before replacement, compare the revision marking, serial number, supply requirements, and configured I/O functions. These checks help reduce commissioning delays and prevent an apparently matching unit from being installed in an incompatible system.

Frequently Asked Questions
What is the Kongsberg 603129 used for?
It is a remote multi-purpose I/O unit used in compatible Kongsberg marine automation systems. Its role is to interface field signals with the wider control system; the precise signal functions depend on the hardware revision and system configuration.
Does the support RS-485 communication?
Available product references identify an isolated RS-485/RBUS interface. Confirm the bus wiring, protocol configuration, and electrical requirements in the technical documentation for the installed revision before connecting the unit.
Can I replace a revision 2.1.1 unit with a revision D1?
Do not assume direct interchangeability. The has been listed with several revision identifiers, including 2.1.1 and D1. Compare the complete part number, revision, serial information, connector layout, and system compatibility requirements before approving a replacement.
Can I hot-swap the while the vessel automation system is running?
Do not assume live replacement is supported. Removing a remote I/O unit may interrupt field data or affect dependent control functions. Follow the vessel’s approved maintenance procedures, assess operational consequences, and isolate the equipment as required by the system documentation.
Does the support firmware v3.1?
The model number alone does not establish firmware compatibility. Verify the actual hardware revision, installed firmware if applicable, and host-system software requirements using the relevant Kongsberg documentation. Do not apply a firmware package intended for a different revision without confirmation.
How can I verify that a replacement is suitable?
Record the complete model and part number, revision, serial number, connector arrangement, supply requirements, and I/O configuration of the installed unit. Compare those details with the replacement and the vessel’s wiring diagrams. Request a functional test report where available.
Is the available new, refurbished, or surplus, and what warranty applies?
Availability depends on the individual unit. Ask the supplier to identify its condition as unused stock, used, or refurbished; state what testing has been completed; and provide written warranty terms. For legacy marine equipment, condition and revision documentation are important parts of the procurement decision.
Procurement note: Specify Kongsberg , part number 603129, along with the installed revision and serial information whenever possible. Confirm the electrical ratings and I/O assignments from the correct technical manual before installation or commissioning.
