Product short description:
  • 16-bit DAC
  • 16 channel voltage output
  • Wide temperature range
  • PCIe bus interface

The AP231 outputs analog voltage signals to drive up to 16 devices. When used with a carrier that holds two AcroPack® modules, up to 32 voltage outputs can be obtained from a single card cage slot.

AP231: 16 Voltage Outputs, 16-bit DAC Module Description

The AP231 outputs analog voltage signals to drive up to 16 devices. When used with a carrier that holds two 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.

The AP231 supports 6 independent software selectable output ranges plus capabilities to monitor the status of each output.

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.

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 AP231 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 uses the same mPCIe standard board hold down stand-off 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.

The AcroPack® product line updates our popular Industry Pack I/O modules with a PCIe interface format. This COTS tech-refresh design 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.
