REL-32.PCI User Manual 
Introduction 
The REL-32.PCI provides 32 reed relays that can switch power, data or other 
electronic signals for control applications. The outputs provide high quality, long 
life, low current (10 Watt maximum), dry contact switch closures. Reed relays are 
well suited for low current applications. The relays are normally open, and will close 
when energized. The REL-32.PCI is PCI 2.1 bus compliant. 
The REL-32.PCI is designed to be used with a variety of Operating Systems 
including Windows 98/NT/ME/2000/XP, Linux and DOS. The SeaI/O API 
(Application Programmer Interface) included on CD with the REL-32.PCI provides 
a variety of useful high-level function calls implemented as a Windows dynamic 
link library (DLL) and as a Linux kernel module and library. In addition to the API, 
SeaI/O includes sample code and utilities to simplify software development.
