VME carrier card provides I/O interface for four I/O modules VME64-compliant connectors increase the quantity of rear I/O connections beyond standard VME capabilities to take advantage of the high channel density available with IndustryPack I/O modules. Acromag's AVME9670is a nonintelligent slave board that interfaces four IndustryPack I/O modules to the VMEbus. Mixing and matching various analog, digital, serial, or other I/O modules on this full-height (6U) carrier card provides a customizable I/O board to save card cage slots. The AVME9670 uses VME64-compliant connectors to increase the quantity of rear I/O connections beyond standard VME. Although the rear connectors are VME64, the electrical interface is standard VME A24/A16. This allows nearly all CPU products to gain full access to the IP modules. Acromag,Wixom, MI; (248) 624-1541.
