The C387 is a single-width, 6U, CompactPCI module with up to 256 digital input/output channels. The C387 base board supports 128 channels of TTL I/O. Four mezzanine card sites can be populated with other forms of digital I/O including isolated input, isolated output, relay output, AC switch output or differential I/O. The mezzanine card concept allows multiple digital I/O types to be configured within a single module to match the application requirements.
Pattern Recognition and Change Of State detection are included. Both operations can be used on the base card as well as span to the mezzanine channels. Input and output strobes are provided for connection to external sources. The digital inputs and outputs are available on 3 double stacked 68 position high density connectors.
