Product catalog summary
Specifications:
The document outlines the specifications for an analog heading display device that processes NMEA input data from a magnetic compass. The device features a 160 mm diameter analog display with a 1° card division. It supports digital data input according to IEC 61162-1 (NMEA 183A) and operates at a data transmission rate of 10 to 30 times per second. The device requires a main and emergency power supply of 24 VDC with automatic change-over and consumes 20 VA without illumination.

Procedures:
The device is designed for flush mounting and includes mounting clamps and terminal blocks for connection. It is equipped with an automatic check of input signals and a power failure alarm for main/emergency supply voltage. The device is certified according to EU MED and IEC 60945 standards.

Norms and Standards:
The device complies with IEC 61162-1 and NMEA 183A standards for digital data input. It is type approved for use with REFLECTA magnetic compass binnacles according to IMO A.382(X) and IMO A.694(17) standards.

Recommendations:
The document suggests using the device with a magnetic compass and a corresponding NMEA converter unit. It also mentions a variant, analog:trueNEMAcourse, for displaying true heading from sources like gyro or GPS compasses.

Additional Features:
The device includes a dimmable illumination feature and offers a remote light dimmer option with a 15 m cable and plug. It is designed for installation with screws and brackets from behind and has a weight of 2 kg. The front of the device is rated IP44, while the back is rated IP22.
