This unit
The Keithley KPCI-PIO24 is a 32-bit PCI-bus digital I/O module that provides 24 TTL-level parallel I/O lines for industrial automation, data acquisition, and process control applications. The module organizes its I/O capability into three independent 8-bit ports (PA, PB, and PC), each independently configurable as input or output under software control. Port PC can be further subdivided into two 4-bit half ports for enhanced application flexibility. Built around the AMCC S5933 PCI bus controller, the KPCI-PIO24 supports plug-and-play operation and leverages the PCI bus 32-bit architecture for reliable integration into host systems.
