Product Brief Description

The Rolls-Royce Weidmuller RRAIO16 is a rugged 16-channel mixed analog input and output module developed for the Rolls-Royce Helicon X3 marine vessel control and alarm monitoring system. Co-designed by Rolls-Royce Marine and Weidmüller, this marine-grade I/O card serves as a field interface to collect analog sensor signals and output control commands. It is built to withstand heavy vibration, humidity and wide temperature fluctuations on ships and offshore assets.

Product Functions

• 16 configurable analog channels for 4-20mA current signal acquisition and control output
• Supports frequency / pulse input for engine tachometers and flow transmitters on selected channels
• Converts field analog signals into digital data and communicates with the Helicon X3 main control unit
• Onboard hardware diagnostics for wire break, short circuit, overrange and module health fault detection
• Galvanic isolation between field side and control bus to suppress marine electrical interference
• Integrated alarm signal processing for machinery monitoring and vessel safety management

Application Scenarios

• Marine vessel propulsion control and main engine monitoring system
• Offshore platform machinery alarm and condition monitoring
• Shipboard auxiliary systems: cooling, lubrication, fuel and tank level measurement
• Marine power generation and generator set parameter monitoring
• Cargo ship, tanker and FPSO centralised alarm monitoring system (AMS)
