Overview

The smallest, lightest, and lowest power consumption Altitude Digitizer on the market.

The SSD120-35C-RS232 is a solid-state Altitude Encoder that is designed to provide a rugged and reliable altitude digitizer for applications where size, weight and economy are critical. Incorporating one ICAO gray code port, as well as two RS232 serial altitude data outputs, this encoder is a simple and robust addition to any avionics installation requiring accurate pressure altitude information for multiple aircraft systems.

The two asynchronous RS232 outputs provide altitude data on the serial data protocol which is commonly used to provide pressure altitude data to ADS-B, GPS, Auto-Pilots, Transponders and other navigation devices. Six (6) serial data protocols are available. The data protocol is selected through internal shunts or via software set-up. Resolution of the serial altitude data may be set to 100 feet or 10 feet through internal shunts.

Operating Pressure Altitude Range: -1000 to +35,000 feet
