Digital I/O Module
For detailed information on this component refer to page 10A-18.
Important: The digital I/O module uses the cabinet’s back panel as a heat
sink for dissipating excess heat during operation. It is important that the
unit be mounted on a smooth, metal, back panel to provide good thermal
conductivity.
