The Tracer-E is a PC/104 digital I/O board that provides 48-lines of 8255 compatible general purpose digital I/O and three 16-bit 8254 compatible counter/timers.  All digital outputs including the counter/timer outputs are high-current.  It is designed for use in systems where high reliability is of utmost importance while operating in harsh environments.

High-current digital outputs can sink 65mA and source 15mA over the entire range of operating temperature.  This is true even while operating at high temperatures.  Wide operating temperature range of -40^oC to +85^oC is standard. No up rating, no hassles.

LED Status indicator.  Useful in determining general status and in system debugging.  A wide variety of signals can be routed to the LED via software selection.  The LED can be configured to observe up to 16 different board signals, see page 22 of the manual.  Great for development and field service, Life gets easier.

8255 Software compatible interface structure provides two 8255 compatible I/O ports that provide 48-lines of general purpose I/O.

Direct interfacing to OPTO-22’s isolated I/O racks.  Digital I/O connectors are organized to allow direct connection to OPTO-22’s isolated I/O racks including the G4 series, the PB16-H, PB16-J, PB16-K, PB16-L, PB8H and the PB24HQ.
