The A6pci1427 is a digital I/O CompactPCI board that supports HotSwap. The 64 input and 64 output channels are all photo-coupler isolated for improving noise resistance.
Interrupts
8 input channels can be used for interrupt requests to the CPU. Either the on-off or off-on transition of digital input can be set as the interrupt trigger for each channel.
Digital filter
Built-in digital filter is provided for preventing malfunctions due to chattering. The time constant of the digital filter is software programmable and can be set for every 16 channels.
