MD36/5D DUAL CHANNEL SYNCHRO TO NMEA INTERFACE

DESCRIPTION

The MD36/5D is a solid-state Dual Channel Synchro to Digital Interface. It simultaneously converts two channels of ac synchro transformer based transmissions of ships heading from legacy equipment into two channels of modern IEC61162-1 (NMEA 0183) compliant digital transmissions.
Constructed in a robust die cast aluminium enclosure and finished in RAL9005 Jet Black fine texture powder coat paint, the MD36/5D is designed to complement existing marine navigation equipment.
Bulkhead mounted as standard. Compact and rugged, the MD36/5D offers a compact Synchro to NMEA interface solution for locations where available space is limited.
The MD36/5D Synchro to NMEA Interface from Marine Data, easy to install and simple to maintain.

FEATURES

• IP Converts 2x Analogue 3-Phase Synchro to 2x Digital NMEA 0183
• Multiplexer to combine 2 channels of NMEA into 1 combined channel NMEA output
• Allows legacy equipment to connect to NMEA systems
• 115 V, 400 Hz Reference Voltage
• 90 V per phase Synchro
• Low Power Consumption
• Compact and Robust

APPLICATIONS

• Suitable for converting from a three-phase synchro transmission format to a digital NMEA 0183 (IEC61162-1) transmission format. This is especially useful for retro-fitting legacy systems with modern equipment requiring a digital transmission of ships heading
