Table 8 - 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)
