Product short description:
- 12-bit DAC
- 8 channels voltage output
- Isolated analog voltage output
- Extended temperature range
- PCIe bus interface
The AP226 outputs analog voltage signals to drive up to 8 devices. When used with a carrier that holds four AcroPack modules, up to 32 voltage outputs can be obtained from a single card cage slot.
AP226: 8 Isolated Voltage Outputs, 12-bit DAC Module Description
The AP226 outputs analog voltage signals to drive up to 8 devices. When used with a carrier that holds four AcroPack modules, up to 32 voltage outputs can be obtained from a single card cage slot.
Each output channel has its own 12-bit D/A converter (DAC). Individual DACs are faster, and they eliminate glitches typically caused by the re-acquisition process of sample and holds found on multiplexed output boards.
Individual channels also have double-buffered data latches. You can select to update each output when it is written to, or to update all outputs simultaneously. Simultaneous outputs better simulate linear movements in motion processes.
The AP226 supports 6 independent software selectable output ranges plus capabilities to monitor the status of each output.
Designed for COTS applications these analog output modules deliver high-density, high-reliability, and high-performance at a low cost.
AcroPack modules are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.
The AP226 modules are 70mm long, 19.05mm longer than the full-length mini PCIe card. The board’s width is the same as mPCIe board and use the same mPCIe standard board hold down standoff and screw keep out areas.
A down-facing 100 pin Samtec connector will mate with the carrier card. Fifty of these signals are available as field I/O signals.
