Abaco Systems / SBS / Greenspring IP-UNIDIG-BUF 24 Differential I/O IndustryPack Module

The Abaco Systems IP-UNIDIG-BUF is a single-wide Type I IndustryPack module delivering 24 individually programmable digital I/O channels. Each line configures dynamically as input or output, enabling flexible integration into industrial control and simulation systems. Double-buffered input and output capability allows simultaneous latching of multiple I/O signals via cascadable external clock triggers, supporting both rising and falling edge detection. Master/Slave synchronization mode enables coordination across multiple modules.
