KONGSBERG RCU502 | Remote Controller Unit
Real-Time Process Control Computer for Marine & Offshore Dynamic Positioning & Thruster Systems
1. Product Overview
The KONGSBERG RCU502 is a rugged, high-performance Remote Controller Unit (RCU) built for real-time process control in marine and offshore installations, approved for Ex Zone 2 hazardous areas. At its core is a 400 MHz embedded PowerPC™ processor with 32 MB SDRAM and 16 MB flash, delivering fast control algorithm execution and reliable data processing for dynamic positioning (DP), thruster control, navigation sensor integration, and integrated process monitoring. It integrates dual Ethernet LAN (10/100 Mbps) for process networks, dual RedundancyNet interfaces for system redundancy, 4 digital inputs/outputs, and 12 multi-protocol serial ports (RS-232/RS-422/RS-485) supporting Modbus, NMEA 0183, and CANopen for seamless integration with sensors, actuators, and third-party marine automation systems. With a -40°C to +85°C operating range and robust construction, it excels in 24/7 critical marine applications requiring precision control and fault tolerance.
