Acromag Combines A/D, D/A, Digital I/O And Counter/Timer Channels On Their Newest AcroPack Rugged Mini PCIe I/O Module

The new AP730 provides a mix of analog and digital input and output channels on a single mPCIe-based module for high-density, high-reliability data acquisition and control applications.

Acromag adds another military-grade measurement and control module to their AcroPack series of ruggedized mini PCIe I/O modules. The new AP730 multi-function I/O module performs analog input, analog output, discrete I/O and counter/timer functions. A variety of carrier cards can host up to four modules and are available in PCIe, VPX, XMC, CompactPCI-Serial, and mini-ITX embedded computing platforms. These boards are designed for commercial off-the shelf (COTS) applications in defense, aerospace, and industrial systems to provide a high-density mix of I/O signal interfaces in compact computing environments. With the AP730’s single-module combination of analog and digital I/O functions, system integrators can use remaining carrier mezzanine slots for serial, Ethernet, avionics, and CAN interfaces, or FPGA signal processing with other AcroPack modules.

Each AP730 module features a high-density mix of 28 I/O channels and 32-bit counter/timers in a 30 x 70mm card. Eight differential analog inputs (0-10V, ±10V ranges) feed a 16-bit A/D converter capable of sampling at nearly 800KHz. Four analog output channels have individual 16-bit D/A converters with a 7.5µS settling time. Programmable I/O ranges, sequencing, interrupts, memory allocation, and other controls are supported, as well as external triggering. The bidirectional digital I/O is configured as two 8-channel groups with TTL-compatible thresholds and programmable change-of-state or level interrupts. Counter/timers perform quadrature, frequency, and period measurement functions plus pulse width modulation and waveform generation operations. DMA transfer support efficiently moves data between module memory and the PCIe bus to unburden the system CPU and increase performance.

“Increasing demand for more efficient size, weight, and power (SWaP) computing is driving the need for high-density, multi-function I/O modules like the AP730,” stated Robert Greenfield, Acromag’s Business Development Manager. “The compact yet rugged AcroPack mezzanine is ideal for interfacing a mix of signals in the tightest footprint on PCIe servers, VPX chassis or small form factor computers.”

AcroPack mezzanine modules improve on the mini PCI Express architecture by adding a down-facing 100-pin connector that securely routes the I/O through a carrier card without any loose internal cabling. Carrier cards for rack-mount, field-deployable, industrial chassis, desktop, and small mezzanine computing platforms let you combine up to four I/O function modules on a single computer board. More than 25 models are available for data acquisition, signal processing, test & measurement, command/control, and network communication applications. Software tools support embedded applications running on Linux, Windows, or VxWorks operating systems.
