BBG-RSSS Serial to Synchro Converter

Applications

• Radar Systems (antenna azimuth)
• Navigation Systems (gyrocompass, speedlog, course, pitch, and roll)
• Industrial Processes (position, velocity)
• Meteorology Instruments (wind speed and direction)
• Many Others

The RSSS is factory configurable to customer requirements for easy field installation. Models available include 6.81V resolver, 11.8V and 90V synchro at both 60 and 400 Hertz. The RSSS provides two dual redundant channels of serial to high power synchro conversion. Each channel has its own power supply and is fault protected against over current and over temperature faults. In addition, the RSSS provides remote control of outputs, local and remote BIT status and internal kick circuitry for added control and protection. An onboard microcontroller configures the card from power up or reset and provides all signals and control to read the serial input information and output the synchro/resolver information.

Health monitoring of each 1X/36X channel for overcurrent, over-temperature and loss of reference is provided via a contact closure status signal. Serial data formats, power outputs, synchro and resolver voltages and frequencies are factory configured to user requirements. The BBG-RSSS-90-400-1 operates on 115 Volt, 60 Hz AC power to convert serial inputs into high power synchro outputs. The RSSS accepts serial data in RS-232, RS-422, RS-423, RS-485, or MIL-STD-188C protocols. Serial baud rates are switch selectable at: 2400, 4800, 9600, 19,200, and 38,400 bits per second. Default serial input is 4800, 8 bits, no parity, and one stop bit (4800, 8, N, 1).
