AP342E-LF AcroPack providesfast, high resolution, simultaneous A/D conversion of up to six channels. Simultaneous channel conversion and on-board memory enable megahertz throughput rates. Programmable interrupts simplify data acquisition by providing greater control.

These modules have twelve differential analog inputs which are sampled as two six-channel banks. Six A/D converters (ADCs) permit simultaneous conversion of up to six channels in a bank.

A FIFO buffer holds the first bank’s data while the second bank is converted. Conversion of each bank requires only 8µS, and all 12 channels can be sampled in just 16µs.

Flexible configuration options give you extensive control over the conversion process. The channels or bank to be converted, timing, scan mode, and other parameters are user-programmable. Interrupt support adds further control to flag a FIFO that is full or filled to a user-defined threshold level.

Designed for COTS applications these analog input modules deliver high-density, high-reliability, and high-performance at a low cost. 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.

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

The AP342E-LF 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 they 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.

  • Description

    An application programming interface with function routines for AcroPack modules/carriers. Customizable for other operating systems.

    Function Libraries for VxWorks

    Acromag’s software development tools greatly simplify the interface between AcroPack I/O boards and your application program. Libraries provide easy-to-use C function routines that quickly integrate with your application. The C functions are ready for use “as-is,” but they are also easily customized for your unique application.

    DLL Driver for Windows

    This package provides DLL driver level support for Acromag’s line of AcroPack products.

    AcroPack Windows Driver Software consists of low – level drivers and Windows Dynamic Link Libraries (DLLs) that facilitate the development of Windows applications accessing Acromag AcroPack I/O modules.

    The software includes kernel drivers and DLLs for both 32 and 64-bit versions of Windows. Applications developed to run on 32-bit versions of Windows use the 32-bit kernel drivers and 32-bit DLLs. Applications developed to run on 64-bit versions of Windows use the 64-bit kernel drivers and either the 32-bit or 64-bit DLLs. Except where noted otherwise, the usage of the 32-bit and 64-bit DLLs is identical.
