The Keithley PIO-32OUT is a 32-channel relay output board for IBM PC and compatible computers, providing switched control of external devices through individual reed relay channels. Each channel delivers up to 10 W switching capacity with 0.75 A maximum current and handles voltages to 30 V RMS, 42.4 V peak, or 60 V DC. The board installs in a standard ISA expansion slot and operates via DriverLINX software, supporting Windows 95/98/NT on Pentium-class processors. Channel-to-channel isolation and Form A reed relay contacts enable flexible integration into industrial control, automated testing, and data acquisition systems.
