Note 1
The maximum allowable total external circuit resistance is calculated from:
R max = 50(Vs
– 11)
Note 2
Where the supply voltage is higher than 28 volts
and
the ambient
temperature higher than 25°C, then a minimum value of loop resistance is
required:
R min = (Vs
– 28)(t – 25)
Where Vs = supply voltage (volts) and t = ambient temperature (°C)
E.g. at 36 volts supply and 85°C ambient, the value of RL must be between
480 ohms and 1200 ohms.
