» Functional Description
The P8R8DIO is an 8-channel isolated digital input and 8 channel relay output interface board designed for control and sensing applications.
This board is easily installed in any PC/AT/XT or compatible computer.
The P8R8DIO can be used in various applications including load switching, external switching, contact closure and others.
The P16R16DIO has one 37-pin D-Sub female and one 40-pin header. It can replace two P8R8DIO.
