AP236: 16-bit DAC, 8 channels, isolated analog voltage output module description

The AP236 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 16-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 AP236 supports 6 independent software selectable output ranges plus capabilities to monitor the status of each output.

Designed for COTS applications these modules output 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.

AcroPack modules are RoHS compliant and ideal for military, defense, automation, aerospace, scientific, and development labs industries.

The AcroPack®  product line updates our popular Industry Pack I/O modules with a PCIe interface format. This COTS tech-refresh offers a compact size, low-cost I/O, the same functionality and memory map of the existing IP modules in a rugged form factor. Combine different AcroPack modules on one carrier for a simplified modular approach to system assembly.

The AP236 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.
