Technical Parameters and Characteristics
The module operates on 24 VDC nominal power supply, with acceptable input voltage range of 18 VDC to 30 VDC and typical power consumption of 12 W. It is equipped with multiple digital input and digital output channels for discrete signal acquisition and relay drive, alongside analog input and analog output ports to receive and transmit 4-20 mA process signals. Integrated RS485 and Ethernet communication interfaces support proprietary Rolls-Royce marine bus protocols and standard industrial protocols to communicate with HMI panels, remote I/O modules and main propulsion controllers. Front panel LED indicators clearly display power status, communication activity and fault alarms for convenient on-site inspection and troubleshooting. Its operating temperature ranges from -20 °C to +60 °C, storage temperature spans -40 °C to +85 °C, and it can withstand non-condensing relative humidity up to 95%. The metal housing provides effective electromagnetic shielding against electrical interference on ships and offers protection level IP20 for cabinet mounting. It has passed vibration and shock testing complying with marine standards, and is approved by major marine classification societies. Internal self-diagnostic functions continuously monitor circuit health, power supply and communication status, and trigger fault alarms when abnormal conditions occur. The module supports hot replacement under appropriate system safety procedures to reduce vessel downtime during maintenance. It meets EMC requirements for marine vessels and complies with relevant marine electrical equipment standards.
