The 8011 digital I/O PCI interface provides 8 optically isolated inputs and 8 Form C relay outputs. The inputs protect the PC and other sensitive equipment from spikes and ground loop current that can be generated in industrial environments, while the outputs provide higher current capabilities (up to 2A) and are optimized for 24V operation. Form C relays can be wired for either normally open or normally closed operation. Sealevel's SeaI/O Classic software drivers and utilities make installation and operation easy using Windows 98, ME, NT, 2000, XP and Vista operating systems.
