The Abaco Systems / VMIC VMIVME-1150-323 is a 64-channel optically isolated digital input board for VMEbus systems. It acquires logic-level signals across a wide voltage range with 1,000 V sustained and 7,500 V pulsed isolation, making it suitable for industrial control, data acquisition, and signal monitoring in harsh electrical environments. The board supports 8-bit or 16-bit data transfers with individually addressable ports, configurable input polarity, and jumper-selectable filtering for noise rejection.
