Press Release Summary:
Respectively featuring 48 and 24 channel high-current TTL DIO lines, PCIe-DIO-48S and PCIe-DIO-24S offer change of state detection and interrupt capabilities. Products are compatible with industry standard 8255 PPI and offer two 50-pin male headers with 24 digital lines each. User interrupt pin is featured on each DIO connector, and all 48 DIO lines are buffered with 32 mA source/64 mA sink current capabilities. All 4- and 8-bit ports are independently selectable for inputs or outputs.
