This unit
The Abaco Systems VMIVME-2528-000 is a 128-bit TTL Digital Input/Output board engineered for VMEbus systems requiring high-density signal interfacing. This double Eurocard (6U) module delivers 128 individually configurable I/O channels with 8-bit and 16-bit data transfer capability, supporting both control and real-time monitoring in industrial automation environments. The board features 24 mA output sink capability per channel, positive or negative true data logic options, and real-time loopback functionality for signal verification.
All outputs initialize in tristate mode via master clear, with automatic release upon the first write transfer to any port.
