Digital RS422 Output Fiber Optic Gyro FOG-DG1-10
The FOG-DG1-10 is a fully digital fiber optic gyroscope featuring RS422 serial output with 200 Hz data refresh rate and 0.02 deg/h bias stability. Purpose-built for modern digital avionics architectures, this gyro eliminates the need for external ADC conversion while providing comprehensive onboard diagnostics.
Key Features
- Native Digital RS422 Output: Direct serial data stream with selectable binary or ASCII protocol formats for plug-and-play digital system integration.
- 200 Hz Data Refresh: Consistent 200 Hz output rate with embedded timestamp for precise time-critical control applications.
- Comprehensive Telemetry: Each data packet includes angular rate, internal temperature, power supply voltage, and BIT status flags.
- Built-In Test (BIT): ≥ 95% fault coverage with continuous background monitoring of light source, photodetector, coil integrity, and electronics.
- Flexible Power Input: Accepts ±5V DC dual supply or 5V DC single supply for streamlined power architecture.
- Low Power Consumption: ≤ 3.5W total, enabling integration into thermally constrained platforms.
