output swings and all inputs are 5 volt tolerant.
TRACER-DIO-5VIO
RUGGEDIZED COTs PC/104 High Drive 48-line DIO and counter-timer module. Safe 3.3 volt
compatibility. This product is an update from our classic Tracer-E. This version provides true 5 volt
output swings and accepts 5 volt inputs as well.
NOTE: some TRACER-DIO-5VIO were shipped using the part number TRACER-E-5VFR. In order to unify all part numbers now
and into the future, part numbers were updated to be of the form TRACER-DIO-<I/O specifier>.
