AcPC330: Analog Input CompactPCI Board

• 16D/32SE input channels
• ±5V, ±10V, 0-5V, and 0-10V input ranges
• 16-bit A/D converter, 8µS conversion time (125KHz)

AcPC330 boards provide fast, high resolution A/D conversion.

The AcPC330 has many features to improve your overall system throughput rate. You can scan all channels or define a subset for more frequent sampling. Burst mode scans selected channels at the maximum conversion rate. Uniform mode performs conversions at user-defined intervals. Both modes can scan continuously, or execute a single cycle upon receiving a trigger.

“Mail box” memory allows the CPU to read the latest data in 32 storage buffer registers without interrupting the A/D converter.

Features & Benefits
“Mail box” memory eliminates scanning interruptions for optimum throughput.
Data register indicates new and missed (overwritten) data values in the mail box.
Programmable interrupts simplify data acquisition by providing greater control.
