Description

The AP323 16-bit A/D AcroPack model monitors 20 differential or 40 single-ended input channels. When used with a carrier that holds four AP modules, up to 160 inputs can be obtained from a single card cage slot.

Software or an external hardware input can trigger A/D conversions for synchronization to external events.

On-board, precision voltage references enable accurate software calibration of the module without external instruments.

Designed for COTS applications AP323 analog input 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 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 in a rugged form factor. Combine different AcroPack modules on one carrier for a simplified modular approach to system assembly.

AP323 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 mates with the carrier card. Fifty of these signals are available as field I/O signals.
