The innovative Aitech C431 is a VMEbus slave card that provides extensive I/O resources including analog-to-digital, digital-to-analog, and opto-isolated digital I/O capabilities for harsh environment applications.
Two ADC devices, a 16-bit and a 12-bit ADC, provide high precision analog-to-digital conversion. The 16-bit device input channels are software configurable, either to 32 single-ended input channels or 16 differential channels or a
combination of both. The 12-bit ADC controls two completely isolated differential channels.
One 16-bit DAC device provides 32 high reliability output levels.
All ADC and DAC devices are advanced high-speed devices enabling high sampling rates.
Digital I/O provides high current opto-isolated channels specifically designed for switch activation and high current switching applications. Each of these opto-isolated channels may be individually configured to operate as input or
The card integrates a sophisticated design totally separating the analog and digital domains allowing it to achieve high quality analog to digital and digital to analog conversions.
The VMEbus interface implemented in the C431 is incorporated in an FPGA logic device providing a simple and reliable interface. The VME interface provides slave functionality only and supports A32/D08/D16/D32 access modes.
The C431 is a low power card delivering high I/O capabilities with minimal power consumption.
The C431 is optionally delivered with a complete set of drivers and optional Built-In Tests (BIT) for all of its on board resources. The drivers integrated into the VME host card environment provide full control and access to all of the C431 modules.
The on-board temperature sensor enables fixing of analog and digital conversion errors.
