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.
Features and Benefits
High-Current Outputs can sink 32 milliamps per channel. This is true even while operating at high temperatures.
Low Voltage: Safe interfacing to 3.3 volt low voltage logic.
Environmental: Wide operating temperature range of -40oC to +85oC
LED status: an LED displays valid card read/write transactions useful for both product development and field status.
Single +5V operation: approximately 500 milliwatts (inputs/outputs unloaded)
Out-gassing and fire avoidance: we do not use any tantalum or electrolytic capacitors in any products.
Reliability: MTBF of 724,559 hours per MIL-HDBK-217F ground benign at 25oC.
Compatibility: Looking for a second source or drop-in? Contact us and we can help.
Production: Designed and Assembled in Wisconsin, USA, utilizing an ISO 9001 manufacturing facility.
Individual Customer Assistance: We will do whatever we can to assist you in designing in our products.
Looking for lower voltage outputs such as 1.8 volts or 2.5 volts or anything in between? With a simple modification of our Tracer we can support any output voltages from 1.8 volts to 5 volts. Contact us for details.
