The dspstak Digital I/O module provides optically isolated digital inputs and outputs to interface to external equipment. There are three standard variations of this module.

  • dspstak Digital I/O - 12 Input / 12 Output
  • dspstak Digital I/O - 8 Input / 16 Output
  • dspstak Digital I/O - 16 Input / 8 Output

Each version has 8 inputs that are active low and share a common positive return terminal.  Each version also has 8 outputs that are open collector with a common ground (emitter) return.

The remaining inputs and outputs are individually isolated. Two terminals are brought out for each input or output. Each input is essentially an LED and series resistor. The outputs are transistors with the collector and emitter exposed. This gives you more flexibility with your external interfacing requirements. 

All connections are brought out to a standard 34 pin latching header (0.100).
