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 rugged mini PCIe I/O modules. The new AP730 multi-function I/O module performs analog input, analog output, discrete I/O as well as counter/timer functions. A variety of carrier cards can host up to four modules; available in PCIe, VPX, XMC, CompactPCI-Serial, and mini-ITX embedded computing platforms. Designed for commercial off-the shelf (COTS) applications in defense, aerospace, and industrial systems, the boards thus provide a high-density mix of I/O signal interfaces in compact computing environments. Because a single AP730 module has a 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 rugged mini PCIe I/O 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, in addition to external triggering. The bi-directional 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 as well as pulse width modulation and waveform generation operations. DMA transfer support efficiently moves data between module memory and the PCIe bus; consequently unburdening the system CPU and increasing 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. Therefore, 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.”Robert Greenfield, Acromag’s Business Development Manager
AcroPack mezzanine modules improve on the mini PCI Express by adding a down-facing 100-pin connector that securely routes the I/O through a carrier card to its integrated external connectors; therefore eliminating internal cables and metalwork modifications. 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 one computer board. More than 25 models are available for data acquisition, signal processing, test & measurement, command/control, and network communication applications. Furthermore, software tools support embedded applications running on Linux®, Windows®, or VxWorks® operating systems.
