Introduction
The DIO-32B digital I/O interface provides 16 optically isolated inputs and 16 reed
relay outputs. The inputs (rated for 3-13V) protect the PC and other sensitive
equipment from spikes and ground loop current that can be generated in industrial
environments, while 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 close when energized.
The DIO-32B 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 DIO-32B 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.
