Abstract
An apparatus includes a remote terminal unit (RTU) having a housing, where at least a portion of the housing includes a shell of thermally-conductive material. The RTU also includes at least one circuit board assembly having at least one processing device configured to communicate with one or more industrial control and automation field devices via one or more input/output (I/O) channels. The at least one circuit board assembly is positioned within the shell. The RTU further includes a heat sink configured to remove thermal energy from the at least one processing device. In addition, the RTU includes a thermal pad configured to receive the thermal energy from the heat sink and to provide the thermal energy to the shell.
