The TRACER-DIO-3.3VIO is a safe COTS high current PC/104 digital I/O and counter/timer module. The module provides 48-lines of 8255 compatible general purpose I/O and three 16-bit 8254 compatible counter/timers all at safe 3.3 volt logic voltages to interface to low voltage logic. This product is an update from our classic Tracer-E. The TRACER-DIO-3.3VIO provides true 3.3 volt output swings and accepts full 5 volt tolerant inputs to interface safely to new low voltage logic. The TRACER-DIO-3.3VIO is 48-lines of 8255 compatible general purpose I/O and three 16-bit 8254 compatible counter/timers. Optional 2 mm connectors and cables, terminal board and cable accessories are available, contact factory.
