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.
For each unit 32 channels are driven to a 44-pin D-Sub connector. Each channel can be either input or output.
The binary inputs/outputs can be universally used in industrial systems. They are optically isolated from the system, which is essential for advanced automotive and industrial applications.
