Calculating Heat Dissipation for the SLC 500
D–5
Use this worksheet to calculate the heat dissipation for your fixed controller.
Procedure Heat Dissipation
1. Calculate
the
heat dissipation
for your fixed controller
.
Write in the watts (calculated watts or maximum watts, see page D-1)
dissipated by the controller, I/O and specialty modules, and peripheral
device attached to the controller
. Add these values together
.
