DDC SB-3622712-365 Digital-To-Synchro PCI Bus Six Channel Converter Card

The DDC SB-3622712-365 is a six-channel Digital-to-Synchro converter card for PCI bus systems that transforms digital input signals into synchro outputs with independent channel operation. Each channel incorporates a dedicated DDC D/S converter, enabling precise motion control and position feedback in industrial automation and aerospace applications. The card supports programmable output amplitudes, resolution settings from 10 to 16-bit, and software-controlled bandwidth configuration. An on-board reference oscillator option eliminates external signal generation and supports configurable reference voltages of 2, 26, or 115 Vrms across the 360 Hz to 10 kHz frequency range with 1.5VA drive capability. All six channels can operate independently with dynamic rotation simulation in both single-speed and two-speed modes. Transformer isolation is available as an optional feature for output channels. The card integrates with Windows and Linux environments via provided SDK and drivers, supports dataSIMS software control, and includes built-in self-test capabilities for detecting Loss-of-Signal, Loss-of-Tracking, and Loss-of-Reference fault conditions.
