686GX233 or 686GX300 Processor Thermal Management
The industrial grade processor IC of the cpuModule must receive adequate cooling to ensure proper
operation and good reliability. The case temperature of the processor must not 85°C The
processor is therefore supplied with an attached fan or heatsink with a thermal resistance of 5° C/W.
The table below shows the maximum ambient temperature allowed vs.
