Product catalog summary
Overview: The MD72RDI is a NMEA-based panoramic rudder angle indicator designed for marine use, featuring a 250 mm diameter display with three faces. It provides clear rudder angle readings from 45° Port to 45° Starboard in 5° increments. The device is housed in a robust aluminium alloy enclosure with dimmer control for illumination, making it suitable for limited space installations on a vessel's bridge.
Applications: The MD72RDI is intended for external use on seagoing vessels, displaying rudder sensor angle data compatible with the NMEA 0183 protocol. It can be used in dual rudder position setups.
Accessories: Includes the MD72VB VESA 100 Deckhead Mounting Kit, with an optional bulkhead mounting kit available.
Related Products: Compatible with the MD61 Rudder Angle Transmitter and MD94DDU Data Distribution Unit, among other Marine Data rudder angle indicators.
Features: The device includes a large format 3-face analogue display, automatic baud rate detection, local and remote dimming control, and automatic warnings for lost data. It accepts digital NMEA 0183 data and can automatically detect previously lost heading data.
Operational Specifications: The MD72RDI offers ±0.5° accuracy and a 40°sec-1 follow-up rate. It features white backlighting and orange pointers, with error indication through pointer parking and flashing illumination. The MTBF is 30,000 hours.
Environmental Specifications: The device has an IP54 rating, operates between -15°C to +55°C, and is RoHS compliant. It has a magnetic permeability of Category ‘A’ and a compass safe distance of 100 cm.
Approvals: Conforms with IEC and IMO standards, with type approval pending.
Physical Specifications: Weighing 2.0 kg, the dimensions are H 64 mm, W 270 mm, D 333 mm. It supports VESA 100 mounting and includes a 15-pin D-sub plug connection.
Electrical Specifications: The power supply is 24 V dc, with data input via RS422 and NMEA 0183 at various baud rates. It includes a 2.5 m multi-core data cable.
