Keithley Instruments PIO-32I/O Overview
Keithley's PIO-32I/O board provides 32 channels of isolated digital I/O on a single board that plugs directly into any available I/O slot of any ISA-bus compatible computer. The PIO32I/O provides 16 channels of optically isolated digital input and 16 channels of electromechanical relay output. All inputs and outputs are isolated to eliminate ground loops, which can cause measurement errors. Onboard safety shields protect the user from inadvertently touching conductors that can have potentially hazardous voltages.
