Description

The KONGSBERG RMP201-8 is a high-reliability remote multiplexer unit within Kongsberg Maritime’s distributed control architecture, engineered for mission-critical marine and offshore automation systems. As a core component of the K-Chief 600 series, this ruggedized module consolidates and processes I/O signals from vessel machinery (e.g., propulsion, ballast, HVAC) with deterministic response times under 50ms. The KONGSBERG RMP201-8 operates as a decentralized node in redundant CAN bus networks, enabling real-time monitoring and control while minimizing cabling in complex vessel designs. Its DNV-GL certified design withstands extreme maritime conditions, including 15g shock loads, 97% humidity, and salt spray corrosion – ensuring continuous operation in dynamic positioning (DP) systems and unmanned machinery spaces (UMS).

Featuring 8 configurable I/O channels, the KONGSBERG RMP201-8 supports mixed analog/digital signals and integrates intrinsically safe barriers for hazardous area installations. The module’s dual-redundant power inputs (24VDC) and automatic bus failover maintain operational integrity during single-point failures. With embedded web server functionality and IEC 61131-3 compliant programming, the KONGSBERG RMP201-8 simplifies integration with Kongsberg’s K-Chief operator stations while providing cybersecurity hardening per IEC 62443 standards for offshore network protection.

Technical Specifications

Main Features and Advantages

Marine-Grade Robustness: Cast aluminum enclosure with triple-coating corrosion protection exceeds offshore environmental standards. The KONGSBERG RMP201-8 sustains performance in pitch/roll conditions up to ±25° with vibration immunity to 7g (5–150 Hz).

Intelligent Signal Processing: Auto-diagnostic routines detect open circuits, short circuits, and signal drift. Integrated galvanic isolation (500V) prevents ground loops. Hot-swappable channel modules enable field reconfiguration without network downtime.

Cybersecurity Architecture: Hardware-enforced secure boot and encrypted firmware updates prevent unauthorized access. Role-based authentication aligns with IMO MSC.428(98) cyber resilience requirements. Event logging to internal RAID storage supports forensic analysis.

Simplified Integration: Pre-configured function blocks (FBs) for pump control, valve sequencing, and PID regulation. Kongsberg’s Marine Electronics Designer (MED) software enables drag-and-drop configuration with automatic documentation generation.

Application Field

The KONGSBERG RMP201-8 dominates marine automation where reliability is non-negotiable. In LNG carriers, it controls cargo tank pressure monitoring systems with SIL 2-certified safety interlocks. Offshore supply vessels utilize its CAN bus redundancy for thruster control during dynamic positioning operations.

Cruise ships deploy the KONGSBERG RMP201-8 for integrated fire detection and HVAC management across 100+ zones. Floating production units (FPSOs) rely on its seawater cooling system automation, leveraging intrinsic safety for Zone 1 hazardous areas. Naval applications include damage control systems where deterministic response ensures watertight door sequencing during emergencies.

Installation and Maintenance

Pre-installation preparation: Verify CAN bus termination resistance (120Ω ±10%) using impedance meter. Mount the KONGSBERG RMP201-8 on vibration-damped panels (ISO 6954 compliance). Separate intrinsically safe wiring (>50mm from non-IS circuits).

Maintenance recommendations: Perform annual dielectric strength test (500V AC for 1 min). Clean electrical contacts with marine-grade corrosion inhibitor. Replace cooling fans at 60,000 operational hours. Validate SIL functions via Kongsberg’s K-Sim simulator during dry-docking.
