Product Overview

The Kongsberg RCU602 is a Remote Controller Unit used within Kongsberg marine automation systems, including the K-Chief platform. Kongsberg’s own certification documentation identifies RCU602 as a Remote Controller Unit and lists it as part of the hardware used in K-Chief marine automation systems.

The RCU602 is intended for distributed control applications onboard vessels, where remote control hardware works as part of the wider automation architecture. K-Chief supports functions including alarm and monitoring, power management, machinery control, cargo and ballast control, vessel-mode management, HVAC-related control, and other vessel automation functions.

For maintenance and spare-parts procurement, the RCU602 is best identified by the model number together with the physical hardware markings and the installed K-Chief system configuration.

Technical Specifications

Kongsberg’s official K-Chief documentation specifically includes RCU602 in the approved hardware list. A current Kongsberg certificate also identifies RCU602 as a Remote Controller Unit and provides an IP2X classification for the module in that certification.

Main Application

The RCU602 is used as part of a distributed marine automation architecture rather than as a standalone generic PLC.

Typical system-level applications include:

• Machinery automation
• Engine-room monitoring and control
• Alarm and monitoring systems
• Power management
• Vessel machinery control
• Cargo and ballast-related automation
• HVAC and auxiliary equipment control
• Distributed remote control applications

K-Chief is an integrated marine automation platform. Kongsberg describes the system as supporting alarm and monitoring, power management, machinery, cargo, ballast, vessel mode, heating, ventilation and air-conditioning control, as well as other vessel automation functions.

System Integration

The RCU602 normally operates as one element within the K-Chief control architecture. It should therefore be evaluated together with the vessel’s existing controller configuration, I/O units, communication network, software version, and application database.

Kongsberg’s certified K-Chief hardware list includes RCU602 alongside other remote I/O and controller components such as RCU502i, RCU601, RMP420, RMP420S, RDIO420S and other distributed modules.

This is important when replacing an installed unit. A physically similar controller is not necessarily a direct replacement unless the system configuration and hardware revision are compatible.

Installation and Replacement Guide

Before replacing an RCU602, record the existing unit’s identification information and installation position.

Recommended procedure:

1. Shut down or isolate the relevant automation equipment according to the vessel’s maintenance procedure.
2. Record the model and hardware identification from the original RCU.
3. Photograph the existing wiring and connector arrangement.
4. Confirm the replacement model and hardware revision.
5. Check connectors for corrosion, loose contacts, or mechanical damage.
6. Use suitable ESD precautions when handling the controller.
7. Install the replacement unit in the original position.
8. Restore the connections according to the vessel documentation.
9. Power up the system according to the approved commissioning procedure.
10. Check controller status, alarms, communication, and associated I/O functions.

Marine equipment should not be commissioned solely from an online product description. The vessel’s K-Chief configuration and approved service documentation should take priority.

Inspection and Maintenance

For a replacement or spare RCU602, a basic incoming inspection should include:

Visual inspection

Check the enclosure, connectors, terminals, mounting points, labels, and PCB area for corrosion, contamination, cracks, or signs of overheating.

Identification verification

Confirm the RCU602 model marking and compare the hardware identification with the controller being replaced.

Connector inspection

Marine environments can expose equipment to humidity, salt contamination, and vibration. Connector condition should therefore be checked carefully before installation.

Functional verification

Where a suitable test environment is available, verify controller startup, system communication, diagnostics, and associated control functions before returning the equipment to service.

Compatibility Note

Kongsberg’s official documents show that RCU602 belongs to the K-Chief hardware family. Kongsberg also continues to provide lifecycle support and upgrade solutions for its K-Chief marine automation systems.

Do not assume that RCU602 can be replaced by RCU601, RCU502i, or another Kongsberg controller simply because the products are all described as remote controller units. These are related products, not automatically interchangeable replacements.

For a direct replacement, verify:

• Controller model
• Hardware revision
• Part number
• K-Chief system generation
• Software/application configuration
• Communication architecture
• Vessel-specific configuration

Condition Information

The referenced eBay listing identifies this unit as Seller Refurbished and notes the condition as “Good condition.”

For a refurbished marine automation controller, buyers should confirm the actual unit photographs, identification label, testing status, included accessories, and warranty terms before purchase.

Ordering Information

For quotation or compatibility checking, provide the complete identification:
