Eight-channel, isolated modules from Acromag eliminate cable for Mini PCIe

Modules from Acromag are claimed to offer cost savings. The AP226 and AP236, rugged eight-channel isolated analogue output modules are designed with a cable-free Mini PCIe interface. They have built-in isolation to prevent ground loops and noise, adds Acromag.

The AP226 and AP236 have been added to the AcroPack series. The modules provide built-in isolated voltage output signals to drive up to eight devices. Designed for COTS, the modules deliver high-density, high-reliability, and high-performance at a low cost, claims Acromag. They support six independent software-selectable output ranges with capabilities to monitor the status of each output along with the same functionality and memory map of existing Industry Pack (IP) modules.

AcroPack modules improve on the mini PCIe form factor by adding a down-facing connector that securely routes I/O signals through the host carrier card without any extra cabling. Carrier cards are available in PCIe, VPX, XMC and other formats. These carriers provide direct access to the field I/O signals through front-panel CHAMP connectors or the rear backplane. With dimensions of only 30 x 70mm per module, up to four AcroPacks can plug into a single carrier card in any I/O combination.

More than 25 AcroPack modules are now offered for a variety of analogue I/O, digital I/O, communication, and FPGA computing functions. Avionics, fieldbus, and other functions are coming soon, promises Acromag.

For easy integration of the AcroPack modules with real-time software application programs, Acromag offers C libraries for Windows, Linux and VxWorks systems. These libraries provide generic routines (source code included) to handle reads, writes, interrupts, and other functions. Demonstration programs enable the developer to quickly exercise the I/O modules before attaching the routines to the application program. This diagnostic tool can save hours of troubleshooting and debugging.

This COTS line of AcroPacks are SWaP-C optimised, RoHS-compliant and are suitable for scientific development labs, military and aerospace applications, the defence industry and automation applications.
