Product Overview
The Kongsberg RCU500 is a marine-grade real-time single-board computer designed as a core remote controller unit for Kongsberg maritime automation platforms. Developed for demanding offshore and shipboard environments, it serves as local processing hub bridging field I/O modules and upper-level operator stations. It executes real-time control logic, collects field sensor data, and manages bidirectional communication within Dynamic Positioning (DP), vessel monitoring and safety instrumented systems. Software compatible with RCU400H and SBC500, it enables convenient upgrade and retrofitting of legacy Kongsberg automation racks.
Core Hardware & Functional Characteristics
Equipped with a 400 MHz PowerPC 8245 processor, 32 MB SDRAM and 16 MB Flash memory, the RCU500 delivers stable deterministic computing to run AIM and DP control applications.
- Integrated 4 digital input channels and 4 digital output channels for direct discrete signal processing
- Rich communication portfolio: dual 100 Mbps Ethernet, dual CAN bus, dual Profibus, SPBus interface for connection with RIO400 remote I/O units; multiple RS232/RS422/RS485 serial ports including isolated variants
- Supports redundant controller architecture and hot-swap replacement in redundant configurations, minimising system downtime during maintenance
- Built-in self-test (BIST), watchdog circuit, over-temperature and fan fault alarms for continuous hardware health supervision
- DIN rail mounting with pluggable terminals; front-panel LED indicators for straightforward on-site diagnosis
- Designed to comply with IEC 60945, IEC 61131-2, IEC 61508 and major marine classification society standards, supporting safety applications up to SIL 3
Typical Application Scenarios
The RCU500 is widely deployed onboard offshore support vessels, drilling rigs, shuttle tankers and merchant ships. It acts as fundamental control hardware within Kongsberg K-Chief, AIM Safe and Dynamic Positioning systems.
- Dynamic positioning system local control and signal processing
- Vessel alarm, monitoring and machinery control systems
- Offshore wellhead control, fire & gas monitoring and safety interlock systems
- Retrofit maintenance for existing Kongsberg automation racks and marine control panels
Sourcing & Commissioning Guidelines
- Confirm full part identifier RCU500 during procurement; different hardware revisions are not fully interchangeable without compatibility verification.
- Implement ESD protection before handling the unit to avoid circuit damage.
- After installation, verify all communication bus wiring, download project control configuration and test data exchange with RIO400 I/O modules and operator stations.
- For redundant system setups, complete hot-swap function validation before restoring vessel operation.
Common Field Faults
- Communication interruption: mismatched bus parameters, improper cable termination or damaged SPBus/Ethernet links
- Intermittent control anomalies: loose terminal connections or ageing onboard memory components
- Continuous fault alarm: excessive cabinet temperature or internal fan failure
Version 2 (Concise Category Listing Description)
Kongsberg RCU500 Remote Controller Unit
The Kongsberg RCU500 is a high-performance marine remote controller unit built on real-time single-board computer architecture. It functions as a key processing node for Kongsberg DP systems, vessel automation and safety control solutions.Featuring abundant multi-type communication interfaces, support for redundant operation and hot swapping, this controller connects RIO400 remote I/O units and executes local real-time control logic. Compliant with marine environmental and functional safety standards, it is suitable for offshore platforms and all types of seagoing vessels.Software compatibility with RCU400H and SBC500 makes it a preferred spare part for legacy system retrofits and maintenance. Full part number confirmation is required before ordering; on-site configuration and communication testing are necessary after every hardware replacement.
