Keithley introduced the KPCI-PIO32IOA and KPCI-PDISO8A isolated digital I/O data acquisition cards for the PCI bus. These cards provide high-level digital sensing and switching (up to 60 V and 350 mA). With 32 and 16 channels respectively, the KPCI-PIO32IOA and KPCI-PDISO8A can handle a variety of 12 V, 24 V, and 48 V loads common to relays, motors, alarms, lamps, machine vision, and robotic systems. In addition, the KPCI-PIO32IOA and KPCI-PDISO8A use the same software and addressing as Keithley's comparable ISA-bus boards, providing a smooth software transition for users who must upgrade to PCI architecture.
The KPCI-PIO32IOA and KPCI-PDISO8A are optically isolated and offer high voltage transient protection that protects the computer from external noise spikes. Both cards are capable of direct, non-polarized switching and sensing in the range of 0-60 V DC or 0-30 V ACrms and can handle loads up to 350 mA.
