This unit
The Curtiss-Wright/Pentland Systems MPV924 is a 6U VMEbus digital input/output board delivering 96 TTL-compatible channels for industrial control, data acquisition, and automation systems. Each channel is individually programmable as input or output, with group configuration via DATA DIRECTION REGISTER. The board sources VMEbus interrupts across seven software-selectable levels and monitors 16 I/O lines with custom-programmable change-of-state detection. Six 34-way latching IDC connectors provide field access, compatible with Burr-Brown termination panels for screw-terminal wiring.
