Keithley PIO-32OUT 32-Channel Relay Output Board

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. ## Technical Specifications • 32 isolated relay output channels • Reed relay contacts (Form A) • Maximum switching power: 10 W per channel • Maximum current: 0.75 A per channel • Voltage rating: 30 V RMS, 42.4 V peak, or 60 V DC maximum • ISA bus interface • Requires one expansion slot • On-board ribbon header connections ## Key Features • Channel-to-channel isolation for independent switching control • Reed relay construction for reliable switching of resistive loads • TTL-compatible input signal interface with inverted logic • Supports wide voltage range beyond standard digital logic levels • Compatible with Installation Categories I and II per IEC 60664 ## Software & Integration Supplied with DriverLINX configuration software enabling custom application development in Visual C/C++, Visual Basic, or Delphi.
