This unit
The Keithley PIO-32I/O is a 32-channel relay I/O board that delivers optically isolated digital inputs and outputs for industrial automation, process control, and data logging applications. It integrates 16 solid-state MOSFET output channels and 16 solid-state input channels, each with 60V channel-to-channel isolation. The board interfaces directly with IBM PC-compatible systems via standard expansion slot connectivity and includes comprehensive DriverLINX software with test panels, ExceLINX, and DLL/ActiveX drivers for rapid integration into measurement and control systems.
