Digital I/O card

Built on a single-width 6U CompactPCI/PXI module, the CP387 supplies 128 TTL-level digital I/O channels, plus four expansion sites to accommodate up to 128 additional digital channels. These sites can be populated with an assortment of optional I/O mezzanine cards, including isolated input, isolated output, relay output, AC switch output, and differential I/O. Data transfers to and from the CP387 are programmable and support 16-bit and 32-bit data words. Onboard flash memory can be used to restore basic digital input and output configuration parameters on power-up. These parameters include the connection of either pull-up or pull-down resistors, the direction of digital I/O channels, and the initial power-up values of digital output channels. Price: $2130.
