BBG-SDU-GDMS1

The BBG-SDU-GDMS1 converts two NMEA serial data inputs to four synchro outputs while also providing two isolated NMEA outputs. It provides four medium-power synchro signal outputs and two isolated NMEA serial data outputs.

Users can access synchro outputs through DIN rail terminal blocks as listed in the connector list. The synchro scaling is determined by the Serial-to-Synchro converter module switch (S1) during power-up or reset.

The front panel Input Select switch lets users toggle between primary and secondary serial inputs, while indicator LEDs show the active serial data source for each channel.

The system includes two fully redundant serial output channels, with input and output serial message formats configured to customer specifications.

Each Serial and Synchro to Parallel PCB processes one synchro or serial input, converting it into a digital angle for output to a Synchro Booster Amplifier.

Jumper settings and the configuration switch at power-on or reset define the system's functionality.

During startup or reset, an onboard microcontroller reads the configuration switch, sets up the interface card, and manages all signals and controls to acquire, process, and output the data.

The SDU’s synchro output channels are protected against overcurrent and overtemperature faults, with internal kick circuitry adding extra control and protection.

Synchro data formats, power outputs, voltages, and frequencies are factory-configured to meet user specifications.
