Process I/O Board
Handles the dedicated input and output signals required by a specific robot process package such as welding or dispensing.
Process I/O boards are configured for a specific application package rather than general purpose signals. A welding cell, for example, uses a process I/O board to handle wire feed speed commands, arc-on feedback, and gas solenoid control between the robot and the welding power source.
These boards often use a defined pinout matched to the process package software running in the controller, so replacing one with a generic I/O board does not work without reconfiguring both hardware and software.
Because process signals are timing-sensitive, a failing process I/O board tends to show up as inconsistent process quality before it shows up as an outright fault.
