A302 - 128-Channel Binary I/O Card
 

6U VMEbus

This product has been discontinued.

The A302 is an input/output VMEbus target board for 128 binary process signals. The I/Os are divided into four optically isolated units. The card is used for input/output of digital signals with different voltage levels and ground references.
