Product Short Description
Product Introduction
The GE (Acromag) AVME-9668 is a 6U full-height VMEbus non-intelligent slave carrier board designed to interface Industry Pack (IP) mezzanine modules with the VMEbus, enabling flexible I/O expansion for embedded industrial systems. It supports up to four IP modules (analog I/O, digital I/O, counter/timer, serial, FPGA) with front-panel SCSI-2 connectors for field I/O signals. The board provides individually fused and filtered +5V, +12V, -12V power to each IP, supports 8MHz/32MHz IP clocks and two interrupt channels per IP, and operates as a passive VMEbus slave for IP register, I/O, and memory access. It is ideal for rugged industrial, aerospace, and defense applications requiring modular I/O customization with minimal cost and space, replacing multiple dedicated VMEbus cards with a single configurable carrier.
