PCI Express Single Lane 40 Line Digital I/O (3x 71055 PIO), 9 interrupts

Product Datasheet


The PCIe-836C is a PCI Express Digital I/O board based on the industry standard 82C55 PPI Chip. It has 24 channels of digital I/O programmable as inputs or outputs in 3 banks of 8. In addition to this, the PCIe-836C has 1x 16bit high current port, 1x optically isolated line and 8x interrupt sources. These can be extremely useful in instrumentation and control applications.

Compliant with the latest PCIe Express Bus standard, it is suitable for use with most modern PCs. Users will also be happy to know that it is completely pin-compatible with our previous generation of PCI and ISA-bus products. These boards all use the industry-standard DB37 connector.

Communication and control is done via PCI Express and the user access to the DIO and DO channels are done via DB37male and IDC26M/DB25M connectors respectively.
