Description
Product Overview
The Kongsberg RDIO401S 603432 is a remote digital input/output module used in marine automation and control equipment. Kongsberg’s system approval documentation lists the module within the hardware inventory for K-Chief 700 and K-Safe installations, which support functions such as machinery monitoring, power management, alarm management, and safety-related control. The RDIO401S provides a distributed I/O point within the larger control architecture, allowing field signals to be handled through the configured automation system rather than treating each signal as an independent controller function. The precise role assigned to an individual module depends on the host-system design and its approved configuration.
When sourcing the Kongsberg RDIO401S 603432, verify the full part number, hardware description number 301087, and installed revision. Available units are listed with revisions including B1, 2.1.1, and 2.2.0; these identifiers should be compared with the existing module and system documentation before replacement. Supplier information describes the RDIO401S as a remote digital I/O and relay module, while one listing reports a 24 VDC supply. Confirm the required supply, terminal assignments, I/O configuration, and relay characteristics against the relevant technical documentation instead of applying generic values to every revision.
The Kongsberg RDIO401S 603432 is relevant to maintenance planning for compatible K-Chief 700 and K-Safe installations. Before installation, inspect the connectors, terminals, board condition, and revision markings. Establish whether the replacement requires system configuration changes, parameter restoration, or controller-side reconfiguration. After fitting the module, follow the vessel’s approved maintenance procedure and verify the expected digital inputs, outputs, diagnostics, and alarm behavior. Record the installed revision and test results in the maintenance log. This is particularly important when replacing a module in an operating vessel, where incorrect I/O mapping or an unverified output circuit could affect machinery control or alarm functions.
Product Introduction
A failed remote I/O module can interrupt field signal monitoring or control even when the central controller remains operational. The Kongsberg RDIO401S 603432 is documented in K-Chief 700 and K-Safe hardware inventories, making exact revision and system checks essential when selecting a replacement.
Confirm the supply requirements, I/O assignments, and installed hardware revision before commissioning. A matching part number alone does not verify the complete configuration.

Frequently Asked Questions
What is the Kongsberg 603432 used for?
It is a remote digital input/output module listed in Kongsberg marine automation hardware documentation. It is associated with K-Chief 700 and K-Safe installations, where remote I/O supports configured monitoring and control functions.
Can I hot-swap the ?
Do not assume hot-swap support. Check the applicable Kongsberg maintenance procedure and system design. Isolate power and follow the vessel’s approved safety procedures unless the documentation explicitly permits live replacement.
Does the support firmware v3.1?
Support for firmware v3.1 has not been confirmed. Check the installed hardware revision, controller software version, and system release documentation before updating or replacing the module.
Are revisions B1, 2.1.1, and 2.2.0 interchangeable?
Interchangeability is not established by the revision labels alone. Compare the hardware description number, electrical specifications, terminal assignments, and system compatibility requirements. Obtain documented approval before installing a different revision in a safety-related or operationally critical system.
Is the suitable for K-Chief 700 and K-Safe?
The is listed in the hardware inventory for both systems. However, actual suitability depends on the installed system generation, controller configuration, software version, and approved equipment design. Verify those details before procurement.
How can I verify the condition and authenticity of a replacement?
Request clear photographs showing the label, part number 603432, hardware revision, serial number, and connectors. Ask for traceability records where available and a written statement of condition. Functional test results are useful, but their scope should be documented rather than assumed.
Will the replacement retain the original I/O configuration?
Configuration retention is not confirmed for this model. Determine whether I/O mapping and parameters reside in the remote module, the host controller, or the wider system configuration. Back up available settings and validate every affected input and output during commissioning.
Procurement recommendation: Specify Kongsberg , part number 603432, hardware description number 301087. Match the hardware revision and confirm the applicable K-Chief 700 or K-Safe configuration before approving the replacement.
