The Lyngso Marine DNM 401 Dual System Bus Module (P/N 962.002.600) is a communication and control interface module developed by STN Atlas Elektronik GmbH, designed for use within integrated marine control systems. As a dual system bus module, it provides redundant data communication pathways between control nodes, ensuring system integrity and continuity in the event of a single bus failure. This type of module is fundamental to the reliability of shipboard automation and monitoring networks, where uninterrupted signal exchange between subsystems is operationally critical.
Key Features
✓ Dual system bus architecture provides inherent redundancy, maintaining communication continuity if one bus path is interrupted — a key requirement in safety-critical marine control environments.
✓ Manufactured by STN Atlas Elektronik GmbH under the Lyngso Marine platform; specific electrical ratings, dimensions, and certifications are subject to confirmation against vessel documentation.
✓ Compatible with Lyngso Marine DNM 401 series control system configurations; integration with other panels, controllers, or network nodes depends on system architecture and should be verified prior to installation.
✓ Intended for installation within control system cabinets or equipment enclosures in protected onboard spaces; mounting and environmental requirements are typical of marine-grade automation hardware.
✓ Serves as a direct replacement module within existing DNM 401 system installations, supporting scheduled maintenance, fault rectification, and system upgrade programmes without full panel replacement.
Marine Applications
✓ Integrated bridge and machinery automation systems aboard merchant vessels, where reliable inter-module communication is essential for continuous monitoring and control.
✓ Offshore support vessels and platform supply vessels utilising Lyngso Marine or STN Atlas Elektronik control platforms for dynamic positioning and machinery management.
✓ Naval and specialist vessels equipped with DNM 401 series automation networks requiring dual-redundant bus communication between distributed control modules.
✓ Cargo vessels, tankers, and bulk carriers where centralised automation systems depend on uninterrupted data exchange between control nodes across multiple decks and machinery spaces.
✓ Retrofit and upgrade projects on vessels with legacy Lyngso Marine control infrastructure, where like-for-like module replacement is required to maintain system compatibility.
