Table 20 - Field Loop Power Heat Dissipation
The field loop power heat dissipation is generated from the input voltages and
cu the output currents:
1
The maximum field loop power heat dissipation for analogue outputs should
be calculated at an output current corresponding to the smaller of the
Maximum Channel Output Current OR Field Voltage/(2 x Load Resistance)
Backplane Electrical Ratings
To comply with UL/CSA standards use the following voltage and current
ratings for the Processor and I/O Backplanes when designing your power
distribution:

IMPORTANT
These are the maximum allowed electrical ratings given by UL
for the backplane load installed with the relevant TAs and
modules. They are not operating values so don't use them to
calculate the controller power consumption or heat
dissipation values. Refer to the separate topics on estimating
Heat Dissipation and Power Consumption.
