The Kongsberg RCU500 is a high-performance, versatile Remote Controller Unit designed to serve as the local processing intelligence within the Kongsberg K-Chief and AutoChief automation systems. This unit is engineered to manage localized control loops, logic execution, and data concentration, reducing the processing load on the central system while increasing overall system redundancy. Built to marine-grade standards, the RCU500 ensures reliable operation for critical shipboard functions in high-vibration and high-temperature environments.
Product Overview and Technical Specifications
The RCU500 acts as a bridge between the field I/O modules and the dual-redundant Ethernet process bus. It features robust processing power and dedicated memory to handle complex automation tasks independently of the main workstations.

Application Fields
The Kongsberg RCU500 is a fundamental building block for modern vessel management:
- Engine Room Automation: Localized control of cooling systems, fuel oil pumps, and auxiliary machinery.
- Power Management Systems (PMS): Managing load sharing, generator start/stop sequences, and breaker control.
- Thruster Control: Providing dedicated processing for dynamic positioning and steering logic.
- Cargo Control Systems: Coordinating valve manifolds and pump sequences for tankers and bulk carriers.
Product Usage Instructions
The RCU500 should be mounted on a DIN rail within a ventilated control cabinet. To ensure high availability, both 24V DC power inputs should be connected to independent power sources. Communication with the system network is established via the dual Ethernet ports; ensure these are connected to separate network switches for full redundancy. Configuration and logic programming are performed using the Kongsberg engineering toolset. During maintenance, the unit’s status can be verified via the front-facing diagnostic LEDs. Always ensure that the grounding strap is properly connected to the cabinet chassis to protect against electrostatic discharge and electromagnetic interference.
Q&A: Frequently Asked Questions
Q: Does the RCU500 support redundant configurations? A: Yes, two RCU500 units can be configured in a redundant pair (duty/standby) to ensure that control remains uninterrupted even if one unit fails.
Q: Can I connect I/O modules directly to the RCU500? A: The RCU500 typically manages I/O modules via a digital bus (such as CANbus or Ethernet). The specific I/O modules (like the RAi or RDi series) are connected as slaves to the RCU500 controller.
Q: How is the firmware updated on this unit? A: Firmware updates are deployed over the system network using authorized Kongsberg service software. It is recommended to perform these updates only during scheduled maintenance periods.
